FUNCTION
The desk microphones provide a desk surface self-sup-
porting stand to mount the TRANSMIT and PL
MONITOR switches and to support the electret con-
denser microphone element at mouth level. The
TMN1008B/C, and TMN1022B/C are used in Private-
Line squelch systems and provide both TRANSMIT and
MONITOR switches; the TMNI009B/C, and
TMN1021B/C are used with carrier squelch systems and
use only the TRANSMIT switch. The TMN1018B/C is
used in paging applications and includes both
TRANSMIT and MONITOR switches.

FOREWORD
1. SCOPE OF MANUAL
This manual is intended for use by experienced technicians familiar with similar types of
equipment. It contains all service information required for the equipment described and is
current as of the printing date. Changes which occur after the printing date are incorporated
by Instruction Manual Revisions (SMR). These SMR’s are added to the manuals as the
engineering changes are incorporated into the equipment.
2. MODEL AND KIT IDENTIFICATION
Motorola equipments are specifically identified by an overall model number on the
nameplate. In most cases, assemblies and kits which make up the equipment also have kit
model numbers stamped on them. When a production or engineering change is incorporated,
the applicable schematic diagrams are updated.
3. SERVICE
Motorola’s National Service Organization offers one of the finest nation-wide installa-
tion and maintenance programs available to communication equipment users. This organiza-
tion includes approximately 900 authorized Motorola Service Stations (MSS) located
throughout the United States, each manned by one or more trained, FCC licensed techni-
cians.
These MSS’s are independently owned and operated and were selected by Motorola to
service its customers. Motorola maintenance is available on either a time and material basis or
ona periodic fixed-fee type arrangement.
The administrative staff of this organization consists of national, area and district service
managers and district representatives, all of whom are Motorola employees with the objective
to improve the service to our customers.
Should you wish to purchase a service contract for your Motorola equipment, contact
your Motorola Service Representative, or write to:
National Service Manager
Motorola Communications and Electronics, Inc.

Schaumburg, Illinois 60196
4. REPLACEMENT PARTS ORDERING
Motorola maintains a number of parts offices strategically-located throughout the United
States. These facilities are staffed to process parts orders, identify part numbers, and other-
wise assist in the maintenance and repair of Motorola Communications Sector products.
Orders for all parts except crystals, active filters, channel elements, and
“‘Vibrasender’’ ® and ‘‘Vibrasponder resonant reeds should be sent to the nearest area
parts center. Orders for instruction manuals should also be sent to the area parts center.
”®
When ordering replacement parts or equipment information, the complete identification
number should be included. This applies to all components, kits, and chassis. If the compo-
nent part number is not known, the order should include the number of the chassis or kit of
which it is a part, and sufficient description of the desired component to identify it.
Orders for crystals, channel elements, active filters, and reeds should be sent directly to
the factory address listed in paragraph 5.5. Crystal and channel element orders should specify
the crystal or channel element type number, crystal and carrier frequency, and the chassis
model number in which the part is used.
Orders for active filters, PROMs, code plugs, Vibrasender and Vibrasponder resonant
reeds should specify type number and frequency, should identify the owner/operator of the
communications system in which these items are to be used; and should include any serial
numbers stamped on the components being replaced.

PREINSTALLATION INSTRUCTIONS
1. UNPACKING
When unpacking the radio from its shipping carton,
refer to the model chart at the front of this manual. If
any item is missing, contact your Motorola represen-
tative immediately.
2. LICENSING REQUIREMENTS
FCC regulations state that a station license must be
obtained for each radio installation (mobile or base) by
the owner of the equipment. The station licensee is
responsible for ensuring that the transmitter power, fre-
quency, and deviation are within the limits permitted
under the station license. Adjustments to the transmitter
section of the radio may be made only by a technician
possessing an FCC general class (or first or second class)
radiotelephone operator’s license. No license is required
to install, or operate the radio.
3. BENCH CHECK
3.1 INTRODUCTION
Each radio set is adjusted, tested, and inspected
before shipment. However, it is recommended that both
the transmitter and receiver sections of the radio be
checked for proper operation just prior to installation.
3.2 TESTING
The radio should be tested with all cables and ac-
cessories supplied with the radio connected as they will
be in the final installation. The frequency, deviation,
2
and output power of the transmitter should be checked,
as well as the sensitivity, squelch operation, and audio
quality of the receiver. Radios with PL or DPL
capabilities should be operated in the coded squelch
mode to verify proper encode/decode performance.
Refer to the specifications page at the front of this
manual to determine whether the radio is operating pro-
perly. Improper operation can generally be corrected by
touching up the receiver or transmitter alignment.
4. INSTALLATION PLANNING-MOBILE
RADIOS
4.1 GENERAL
Planning is the key to fast, easy radio installation.
Before a hole is drilled or a wire is run, inspect the vehi-
cle and determine how and where you intend to mount
the antenna, radio set, and accessories. Plan wire and
cable runs to provide maximum protection from pin-
ching, crushing, and overheating.
4.2 ANTENNA MOUNTING
The best mounting location for the antenna is in
the center of a large, flat conductive surface. In almost
all vehicles these requirements are best satisfied by
mounting the antenna at the center of the roof. Some
vehicles have a large trunk lid that will provide a good
antenna location. If the trunk lid is used, connect
grounding straps between the trunk lid and vehicle
chassis to insure that the trunk lid is at chassis ground.

4.3 RADIO MOUNTING
4.3.1 General
The trunnion mount allows the radio set to be
mounted to a variety of surfaces. Be sure the mounting
surface is able to adequately support the weight of the
radio. Allow sufficient space around the radio for free
air flow for cooling. Be sure the unit is close enough to
the vehicle operator to permit easy access to operating
controls while he is driving.
4.3.2 Inverted Escutcheon Installation
A front panel escutcheon with inverted lettering
(Motorola Option B96) is available if you plan to mount
the radio above the operator’s normal line of sight. In-
stall the inverted escutcheon as follows:
Step 1. Remove the ON/OFF VOLUME §$and
SQUELCH control knobs.
Step 2. Remove the radio chassis from its housing (see
Housing Removal procedure in SERVICE section).
Step 3. Using a long screwdriver, push on the back of
the upright escutcheon until it is free of the radio hous-
ing front panel.
Step 4. Remove the tape from the back of the inverted
escutcheon. Press the inverted escutcheon onto the
radio housing front panel.
Step 5. Reinstall the radio chassis into the housing. Be
sure the chassis locking tabs properly engage the slots in
the housing. Replace the ON/OFF VOLUME and
SQUELCH control knobs.
4.4 DC POWER AND WIRING
4.4.1 This radio must be operated only in negative-
ground electrical systems. Reverse polarity will
not damage the radio, but the cable fuse will blow.
Check the vehicle ground polarity before you begin in-
stallation to prevent wasted time and.effort.
4.4.2 Connect the red power lead through F601
to the vehicle battery positive terminal. Connec-
ting the red lead to any other positive voltage point in
the vehicle is not recommended.
CAUTION
If dc power is to be controlled by the vehi-
cle ignition switch, a switching relay
(Motorola Part No. 59-813674) should be
used to switch the red power lead. The
vehicle ignition switch, then, controls dc
to the relay coil.
4.4.3 Connect the black power lead to a good
ground point on the vehicle chassis. Do not con-
nect the black lead directly to the battery negative ter-
minal.
4.4.4 The wiring provided with the radio is of
sufficient size to handle the maximum radio cur-
rent demand. If wiring must be added to that provided,
be sure the gauge of the added wire is sufficient for the
current to be carried and length of the added run.
5. INSTALLATION PLANNING—BASE
STATIONS
5.1 ANTENNA SYSTEM
Selecting the antenna system for your base radio
depends on factors beyond the scope of this manual.
Your Motorola representative can help you choose the
antenna system that will best serve your particular
needs.
5.2 RADIO LOCATION
Choose a location for your base radio as close as
possible to where the antenna cable enters the building.
Be sure 117 volt, 60 Hz power is available. Make sure
sufficient air can flow around the radio to permit ade-
quate cooling.
INSTALLATION INSTRUCTIONS
1. MOBILE RADIOS USING TLN5992A
LOCKING TRUNNION
1.1 MOUNTING CONSIDERATIONS
Before attempting to install the locking trunnion
examine the vehicle for suitable mounting locations.
The bracket requires a flat mounting surface at least 8”
x 2” with adequate clearance for inserting the radio set.
The chosen location should also be convenient to the
Gg
vehicle operator and provide access to power and anten-
na connections. Be careful to choose a location which
permits the locking trunnion to be removed from the
mounting bracket. Vehicle operation should in no case
be impaired.
1.2 INSTALLATION
(Refer to Figure 2)
Step 1. Using the mounting bracket as a template,
drill six 5/32-inch holes. If mounting on plastic surface,
use metal backing plate to strenghten installation.
Step 2. Using the six #10-16 x 3/4” screws provided,
attach the mounting bracket to the mounting surface.
Allow 3/4 inch clearance in front of the bracket so lock-
ing trunnion may be inserted.
Step 3. Attach radio to locking trunnion using the two
#10-32 x 1/2” screws provided in the radio.
Step 4. Insert the locking trunnion into the mounting
bracket by first sliding the large flanges into the slots at
the rear of the mounting bracket and then sliding the
small locking flanges into the slots at the front of the
mounting bracket.
Step 5. Lock the locking trunnion into the mounting
bracket using the key provided.
Step 6. Perform Steps 2 through 9 in paragraph 2
below.
2. MOBILE RADIOS USING OPTIONAL
TRUNNION MOUNTING BRACKET
Step 1. Mount the radio set trunnion mounting
bracket. See Figure 3.
Step 2. Mount the antenna, using the instructions pro-
vided with the antenna kit. Run the coaxial cable to the
intended radio set mounting location. If necessary, cut
off the excess cable and install the cable connector.
CAUTION
DO NOT CUT ANTENNA CABLE
unless absolutely necessary. If cable must
be shortened, higher Effective Radiated
Power will be obtained as per tabel below.
Be sure the system is licensed to operate a
higher ERP before cutting cable.
Step 3. Route power wiring, but do not make power
connections and do not tie the wires down. Be sure to
use grommets wherever the wiring must pass through a
metal panel.

Step 6. Complete the power wire installation. Be sure
to leave sufficient slack wire behind the radio set to
make the unit easy to remove and reinstall. Strap the
wire down where necessary being sure the wires do not
make contact with hot areas on the engine. Be sure the
wires cannot be snagged by the operator’s feet or during
the normal vehicle operation. Cut off the excess power
lead length and attach the terminal lugs supplied.
Step 7. If a microphone hang-up box or external
speaker is used, secure wiring to those items as needed.
Allow sufficient slack in wiring for future maintenance.
Step 8. Connect the power leads. Be sure the connec-
tion points are clean and free of paint, dirt, and corro-
sion.
Step 9. Test radio and its accessories for proper
system operation. Check the antenna SWR, using an in-
line wattmeter.

SAFE HANDLING OF CMOS
INTEGRATED CIRCUIT DEVICES
Many of the integrated circuit devices used in com-
munications equipment are of the CMOS (Complemen-
tary Metal Oxide Semiconductor) type. Because of their
high open circuit impedance, CMOS ICs are vulnerable
to damage from static charges. Care must be taken in
handling, shipping, and servicing them and the
assemblies in which they are used.
Even though protection devices are provided in
CMOS IC inputs, the protection is effective only against
overvoltage in the hundreds of volts range such as are
encountered in an operating system. In a system, circuit
elements distribute static charges and load the CMOS
circuits, decreasing the chance of damage. However,
CMOS circuits can be damaged by improper handling
of the modules even in a system.
To avoid damage to circuits, observe the following
handling, shipping, and servicing precautions.
1. Prior to and while servicing a circuit module,
particularly after moving within the service area,
momentarily touch both hands to a bare metal earth
grounded surface. This will discharge any static charge
which may have accumulated on the person doing the
servicing.
NOTE
Wearing Conductive Wrist Strap
(Motorola No. RSX-4015A) will minimize
static buildup during servicing.
WARNING
When wearing Conductive Wrist Strap,
be careful near sources of high voltage.
The good ground provided by the wrist
strap will also increase the danger of
lethal shock from accidentially touching
high voltage sources.

2. Whenever possible, avoid touching any elec-
trically conductive parts of the circuit module with your
hands.
3. Normally, circuit modules can be inserted or
removed with power applied to the unit. However,
check the INSTALLATION and MAINTENANCE sec-
tions of the manual as well as the module schematic
diagram to insure there are no objections to this prac-
tice:
4. When servicing a circuit module, avoid
carpeted areas, dry environments, and certain types of
clothing (silk, nylon, etc.) because they contribute to
static buildup.
5. All electrically powered test equipment should
be grounded. Apply the ground lead from the test
equipment to the circuit module before connecting the
test probe. Similarly, disconnect the test probe prior to
removing the ground lead.
6. Ifacircuit module is removed from the system,
it is desirable to lay it on a conductive surface (such as a
sheet of aluminum foil) which is connected to ground
through 100k of resistance.
WARNING
If the aluminum foil is connected directly
to ground, be cautious of possible elec-
trical shock from contacting the foil at the
same time as other electrical circuits.
7. When soldering, be sure the soldering iron is
grounded.
8. Prior to connecting jumpers, replacing circuit
components, or touching CMOS pins (if this becomes
necessary in the replacement of an integrated circuit
device), be sure to discharge any static buildup as
described in procedure 1. Since voltage differences can
exist across the human body, it is recommended that on-
ly one hand be used if it is necessary to touch pins on the
CMOS device and associated board wiring.
68P81106E84-C
12/10/82- PHI
9. When replacing a CMOS integrated circuit
device, leave the device in its metal rail container or con-
ductive foam until it is to be inserted into the printed cir-
cuit module.
10. All low impedance test equipment (such as
pulse generators, etc.) should be connected to CMOS
device inputs after power is applied to the CMOS cir-
cuitry. Similarly, such low impedance equipment should
be disconnected before power is turned off.
11. Replacement modules shipped separately from
the factory will be packaged in a conductive material.
Any modules being transported from one area to
another should be wrapped in a simlar material
(aluminum foil may be used). NEVER USE NON-
CONDUCTIVE MATERIAL for packaging these
modules.

PREALIGNMENT NOTES
1. In some cases, peak readings may occur at two points in the tuning range of a coil. Always choose point where
slug is nearest top of coil form (away from circuit board).
2. Unnecessary tuning adjustments should be avoided. Usually, only a ‘‘touch-up”’ transmitter alignment is needed.
Complete transmitter alignment is needed in the following cases:
a. After changing transmitter operating frequency.
b. After replacing a component in a frequency-sensitive network.
3. Before beginning a complete alignment, preset tuning adjustments as follows:
Set L120 seven turns from top of form.
Set C613 one turn counterclockwise from full right.
Set C615 fully counterclockwise (full out).
Set L110 (and L111 in 2-frequency models) seven turns from circuit board.

NOTE
Low or no meter 3 reading will be obtained if L110 and L111 are not properly preset.

If a TEK-5 Metering Panel or a S1056-59 Portable Test Set is available, connect the metering panel or test set to
J601 using the appropriate metering adapter cable. The metering adapter cables and directions for their use are
shown in the Test Equipment section. Metering may be accomplished with a 20,000
ohm-per- volt voltmeter if a test set or metering panel is not available. Refer to the metering tables on this page.
Connect an rf wattmeter, terminated in a resonant antenna or 50-ohm resistive dummy load, to radio set antenna
connector J602.
Connect a dc power supply to the power leads of the test cable. Set the power supply output to 13.6 volts.

PREALIGNMENT NOTES
In some cases, peak readings may occur at two points in the tuning range of a coil. Always choose point where
slug is nearest top of coil form (away from circuit board).
Unnecessary tuning adjustments should be avoided. Usually, only a ‘‘touch-up’’ transmitter alignment is
needed. Complete transmitter alignment is needed in the following cases:
a. After changing transmitter operating frequency.
b. After replacing a component in a frequency-sensitive network.
Before beginning a complete alignment, preset tuning adjustments as follows:
Set L120 seven turns into coil from top of form.
Set C613 one turn counterclockwise from full tight.
Set C615 fully counterclockwise tight (full out).
Set L110, L111, L905, and L906 seven turns from circuit board.
eee
CAUTION
Low or no meter 3 reading will be obtained if L110, L111, L905, and L906 are not proper-
ly preset.
eee
aoop
e. Starting with slugs of L225, 226, and 227 flush with tension nut, set slugs six turns above nut.
f. Set L112, L113, L114, L115, and L118 according to the prealignment tuning chart shown in Figure 1.
g. Set power set control R804 fully counterclockwise (as viewed from solder side of board).
CAUTION
While tuning the transmitter, M7 must not exceed 17.5 uA. Adjust
power set control R804 clockwise (as viewed from solder side of
board) as necessary to maintain M7 below 17.5 uA.
4. Keytransmitter for each step in alignment procedure and de-key after alignment step is completed.

OSCILLATOR FREQUENCY ADJUSTMENT
Oscillators should be set on frequency AFTER transmitter has been aligned and BEFORE modulation deviation is set.
On radios with transmitter frequency stability of 2 ppm, refer to instruction section 68P81035E04 before performing
the following procedures (1 and 2 freq. models only).
NOTE
The transmit frequency of this radio should only be adjusted when the ambient
temperature is 82° F (28° C). Because of temperature and voltage variations between fac-
tory and field locations, the frequency measured may not correspond to the assigned fre-
quency. If the measured frequency is between the limits shown in Figure 4, make no at-
tempt to correct the frequency.
If the measured frequency does not fall within the limits shown in Figure 4, it is recom-
mended that the radio be returned to a room temperature environment (approximately
82° F, 28° C) and the frequency reset using the procedure described below.

4 Disconnect the audio signal generator from J601.
5 Key the transmitter and adjust code level set control R342 for a DPL code deviation reading of
900 Hz.
6 Reconnect the audio signal generator to J601-5 and -6. Repeat Steps 1 and 2. Be sure overall
deviation does not exceed +4.75 kHz, including DPL code.

NOTE
To obtain accurate measurement of transmitter deviation in radios equipped with Digital Private-Line binary- coded
squelch, the frequency response of the deviation measuring equipment must be less than 1 Hz. If a deviation meter
with this low frequency response characteristic is not available, the transmitter deviation can be checked by making
the transmitter send continuous Turn-Off code during the measurement. Since the Turn-Off code waveform is
sinusoidal, standard test equipment will then provide an accurate deviation measurement. To make the transmitter
send continuous Turn-Off code, short together the base and emitter plating of PTT Inverter Q309 and key the
transmitter.

PREALIGNMENT NOTES
On Digital Private-Line squelch and Private-Line squelch radio sets, disable the DPL or PL decoder by removing
the microphone from the hangup box.
In some cases, peak meter readings may occur at two points in the tuning range of a coil. Always choose point
where the slug is nearest the top of the coil form (away from the circuit board).
Unnecessary tuning adjustments should be avoided. Usually, the receiver will require only a ‘‘touch-up’’
alignment. Complete receiver alignment is necessary in the following cases:
a. After changing the receiver operating frequency.
b. After replacing a component in a frequency-sensitive network.
Before beginning a complete receiver alignment, preset tuning adjustments as follows:
Set L221, 222, 223, 224 nine turns CCW from fully in position.
Set L213, 214, 215, 216, 217, 218, 219, 220 seven turns CCW from fully in position.
Set L12, 13, 18, 20, 21, 23, 901, 902 flush with the circuit board.
Set L15 and L908 flush with top of coil form.
ao oe
Receiver frequency calculations:
fose = f= 10.7MHz
9
finj = 9fosce = fe - 10.7 MHz;
Where f, = carrier frequency, fose = oscillator crystal frequency, and finj = mixer injection frequency.
Select the highest operating frequency to tune the radio.
If a TEK-5 Metering Panel or a S1056-59 Portable Test Set is available, connect the metering panel or test set toJ601
using the appropriate metering adapter cable. The metering adapter cables and directions for their use are shown in
metering adapter cables diagram in Test Equipment section. Metering may be accomplished with a 20,000 ohm-per-
volt voltmeter if a test set or metering panel is not available. Refer to the voltmeter metering table on this page.
Readings taken with VOM are not accurate if meter panel or test set is connected simultaneously.
Connect a de power supply to the power leads of the test cable. Set the power supply output to 13.8 volts.

NOTES
1. With a wire connected to a 10.7 MHz signal source output, ‘‘spray’’ the signal near Q12 (that is, place the
wire close to Q12) but do not allow the wire to make physical contact with any part of the i-f amplifier.
2. To set signal generator on frequency, either use a counter on the generator output or use the zero beat
method (Step 5). Do not use Meter 2 to set frequency.
3. Ifa peak cannot be obtained adjust L908 until Meter 3 just starts dropping. Do not leave slug at top of coil
form.
4. If either F3 or F4 is unused initially, frequency adjustments should be made on both channels when
additional crystals are added.
20 DB QUIETING SENSITIVITY MEASUREMENT
Connect an ac voltmeter across the speaker.
On PL model radio sets, disable PL by depressing the MONITOR button on the radio set front panel (if the radio
is not equipped with a monitor switch remove the microphone from the hang-up box.).
Turn the SQUELCH control fully counterclockwise.
Turn on the radio set and adjust the VOLUME control until a reading of 2 volts is obtained on the ac voltmeter.
Connect an rf signal generator to the radio set antenna connector. Set the signal generator to the carrier
frequency, and set the generator output level control to minimum. |
Slowly increase the output level of the rf signal generator until the ac voltmeter reads 0.2 volts.
Note the signal generator output signal level. This signal level is the 20 dB quieting sensitivity of the receiver, and
should be no greater than the level specified in the specifications table in the front of the manual.
