Typical Selective Radio Paging System
RADIO POCKET PAGER
These units are carried by personnel
and are a receiver-only portion of the
system. The units alert the paged
party and receive the voice message
but are incapable of transmission.
SELECTIVE ‘“‘HANDIE-TALKIE”’ RADIO
These units are carried by personnel
and are used to alert the person being
paged. After alerting the person, a
two-way conversation may be held
since the units are capable of both
transmitting and receiving. Calls
may also be originated by this unit.
BASE STATION
This station is available ina variety
of models or the existing equivalent
station may be used. It provides
the radio carrier for selective paging
signals and voice and amplifies any
received messages.

ig? 7 DESCRIP TION
The H24FFN Series (l-watt) and H34FFN Series (4-watt) Selective
Call Model Radios described in this supplement are similar to the
counterpart l-watt and 4-watt carrier squelch model radios described
in the attached instruction manual. The unique feature of these radios
is the selective calling capability, with optional ''Private-Line" tone on
transmit. Thus, each radio may be operated as a two-way communi-
cations unit, like the basic model and/or as a pager ina Motorola
selective call radio paging system.
Selective call circuitry, essentially an audio decoder, allows the
radio receiver to respond only to a particular sequence of coded tones
which are transmitted from an associated radio paging station (see
Selective Radio Paging System detail), The tone sequence may be used
for calling an individual radio or a group of radios.
The "Private-Line'! tone on transmit option adds a tone oscillator
or encoder for use with the transmitter to provide ''PL'! encoded
carrier signals. This is especially useful when transmissions are to
_ be directed to a specific location within a radio network where many
receivers monitor the same frequency. Assuming all receivers
within the network are equipped with the 'PL'' on transmit option,
only the ''PL" receiver equipped to decode a tone code identical to that
being transmitted will deliver audio at its speaker. Refer to the model
chart in the front of this supplement for a complete listing of models
available with this option.
es, OPERATION
a. Pre Ope rational Notes
The PREOPERA TIONAL NOTES in the attached instruction | manual
are fully applicable to these selective call models.
-b. Operation
NO wr
The operator must be aware that when the P-T switch is
in the P (page) position, the radio is in pager operation;
Only an alert tone can be heard and no voice messages can
be received. When the P-T switch is in the T (talk) position,
the unit functions as a normal two-way radio capable of
receiving and transmitting.

Figure 1. Controls Location Detail
(1) To Turn On - Place the P-T (page-talk) switch in the T position.
This places the unit in an operational standby condition.
(2) To Adjust Receiver Audio Volume - With a signal being received,
turn the SQUELCH control fully counterclockwise. Adjust the OF F-VOL
control until the desired volume level is obtained at the speaker.
(3) To Adjust the Squelch Control - Turn the SQUELCH control fully
counterclockwise. With no signal being received, turn the SOUELCH conta
clockwise until the noise coming from the speaker just, cuts out (squelches).
The receiver is now set to threshold squelch.
(4) To Monitor Voice - To monitor all on-frequency transmissions,
leave the P-T ‘switch yn thes T position.
(5) Pager Operation - Place the P-T switch in the P position. When
receive the voice message which follows the alert tone.
NOTE
The level of the alert tone will be decreased by removing
jumper JU401 across capacitor C422 on the selective call
printed circuit board. This will not affect the level of the
received voice message.
insure non-interference with others using the same channel. The P-T
switch must be in the T position in order to listen as well as to transmit,
Hold the radio, or remote unit, with the speaker/microphone grille
approximately one or two inches from the lips. Press the push-to-talk
switch firmly, and speak ina natural tone of voice directly into the
microphone. For best results speak slowly and distinctly. Release
the push-to-talk switch when you finish speaking.
F4), On two frequency (T2 - R2) models, F2 selects the F2 frequency
as indicated. However, on two-frequency (T2-R1) models, F2 selects
the transmit frequency or the F1 receive frequency, as applicable.
(8) To Turn Off - To turn the radio off, turn the OFF-VOL control
(9) Storage - Battery considerations must be made when con-
templating radio storage. If the radio is equipped with a mercury
battery, the battery must be removed before storing the unit for a long
period of time. If equipped with a nickel-cadmium battery, refer to the
battery storage information presented in the accompanying manual.
3, DESCRIPTION OF ITEMS
NOTE
Only those items unique to selective call models are
described in this supplement. All common items are
fully described in the attached instruction manual.
a. Chassis Frame
The carrier squelch model chassis frame is identical to its counter-
part described in the attached instruction manual, except for minor
changes required for compatibility with the added selective call circuitry.
For example, a change resulting from the addition of the selective call
circuitry is the removal of receiver coupling capacitor C58.
The ''PL'"' model chassis frame is significantly different than its
counterpart described in the attached manual, In addition to the
aforementioned chassis changes, the ''PL"' chassis is modified for
replacement of the standard ''PL'! tone encoder-decoder circuit board
with a ''PL'' tone encoder board. Also, on the one-frequency 'PL"
chassis frame, ''PL'' ON-OFF toggle switch S4 is removed.
Diagrams applicable to the transmitter and receiver as adapted for
selective call operation are included in this supplement.
b. 'Vibrasponder'"! Resonant Reed
peltintenel S a ea a
The ''Vibrasponder' resonant reed is the frequency controlling
element in-the selective call circuit as well as the "PL" circuit, In
single-code models, two 'Vibrasponder" reeds are used. This is in
addition to the TLN6709B Reed required for the ''PL'' tone encoder,
when supplied. Both TLN8904 and TLN6709 Reed types have identical
ratings; they differ only in size and weight.
ec. wseélective Call Sleeve Kit
pastes lel Mage he ade ae Ne at
The two-reed selective call kit consists of a selective call printed
circuit board, P-T switch, antenna receptacle, and associated wiring.
The printed circuit board mounts two reed sockets, each of which
accepts a plug-in ''Vibrasponder" resonant reed (separately supplied). |
The sleeve is mounted to the chassis metal frame and secured with the
cover retaining bushings.
Carrier squelch (C.S.) and 'PL" variation sleeve kits differ in
Sleeve length. Diagrams applicable to the selective call circuit are
included in this supplement.
Sage ee ee a ee
d. '"Private-Line'' Encoder ("PL'' on Transmit Models Only)
—— ee ey ee
The "PL" encoder circuit board replaces the standard "PL" circuit
board described in the attached manual and is slot-mounted imneneeeee
location, Unlike the standard "PI," circuit, this circuit has no decoder
portion and is not used with a 'PL"' ON-OFF switch. A '"Vibrasponder"!
resonant reed is separately supplied for use with this circuit. Diagrams
applicable to the 'PL" encoder are included in this Supplement,
cate a = 2 tk On ee daa tte a
e. Miscellaneous Parts Kit
aia ae a ne fA fe negre ated oe ag
Each selective call parts kit consists of an escutcheon marked for
selective call operation (and frequency selection on two-frequency model
kits), a P-T knob, and miscellaneous hardware for installation of the
selective call sleeve kit. The 'PL" variation kit differs from the carrier _
squelch version mainly in that it also includes two coils and a capacitor nee
for the installation of the 'PL" tone encoder board. ;
ie Code Identification Label
inn ee ee a ee
The code identification label specifies the individual call or group
call code of the particular 'Handie-Talkie" radio.

4. THEORY OF OPERATION
ae General
ee ess SED
The general theory of operation presented in the attached
instruction manual is also applicable to the selective call models, except
that the ''Private-Line' tone on transmit models (here ''Private-Line"
refers only to the encoding function) includes a 'PL" tone encoder which
is part of the transmitter only. Another significant difference is the
selective call circuitry in the receiver. The single-code model circuitry
consists of an emitter follower, a reed driver, two 'Vibrasponder'!
resonant reeds, two tone amplifiers, two tone detectors, an inhibit gate,
a squelch gate, an oscillator, a talk-page audio gate, and a voltage
regulator all mounted on a separate printed circuit board. The dual-code
models include two of these boards, identical except for resonant
frequencies and ''Vibrasender"! reeds.

the audio signal from the discriminator to the active filter Q7, allowing
further amplification by Q12, Q14, Q15, and Q16. The squelch circuit
Operates in the same manner as a standard receiver.
During pager operation, Squelch operation is different. The P-T
Switch is in the P position which gates ''off"' the audio signal between
the discriminator and active filter. However, the audio signal at the
discriminator is applied to the selective call decoder. If the audio
Signal consists of two tones of the proper frequency and sequence, it
will be decoded to provide two outputs; a pure dc signal,
alert tone,
and an audio

also at zero volts due to noise absence during coded tone reception.
Ql1l turns off, allowing the alert tone to be fed to first audio amplifier
Q12. This allows an amplified alerting tone to be heard at the speaker.
(4) ''Private-Line'' Tone Encoder Refer to Figure 2 or 3 and the
"Private-Line'' Encoder Schematic Diagram
A feedback loop within the ''PL" tone encoder is established when
voltage from the transmitter is applied to reed driver Q601. Q601 shocks
the ''Vibrasponder'' resonant reed into oscillation. The reed output is
applied to class A biased feedback amplifier Q602, which through C603
feeds part of its output back to Q601. The frequency of oscillation is
controlled by the resonant reed. The ''PL'' tone output is taken from the
collector of Q602 and is applied to the transmitter IDC module. The amount
of ''PL'' tone deviation is set by R608.
(5) Selective Call Decoder Refer to Figure 5 and the Selective Call
Decoder Schematic Diagram
There are twotypes of pager models available: a single-code
model and a dual-code model. The single-code model requires two
"Vibrasponder'' resonant reeds. The tone codes required to activate
these reeds are designated A for the first tone and B for the second tone.
Tone A is transmitted for one second followed within 400-milliseconds
by three seconds of Tone B. In dual-code models, the first two reeds
are normally used for individual paging and the second two (designated
C and D) are used for group paging. The paging tones must appear in the
proper sequence to provide a paging tone at the speaker (Refer to Selective
Call Decoder DC Switching Waveforms).
The ''Vibrasponder" reed is an electromechanical device whose
vibrating mass is resonant at a particular frequency. If a tone is applied
to the input coil at the reed's resonant frequency, the vibrating member
will begin oscillating (damped oscillation), mechanically coupling the
input signal to the output coil. Therefore, each reed can be considered
to be a very narrow bandpass filter which passes only the desired paging
tone to the decoder network.
Signals from the discriminator are coupled to a high input
impedance emitter follower (Q401) which acts as a buffer stage to prevent
discriminator loading. The reed driver (Q402) then amplifies the signal
to the desired voltage level across the reeds. CR401 limits the voltage
swing across the reeds to minimize voice and noise peaks at the reed's
resonant frequency. If Tone A is the signal being sent, it will be present
at the output of reed A and will be amplified by the class A biased tone
amplifier (Q403) and coupled to the tone detector consisting of Q404 and
Q405. With both tone detector transistors saturated, a dc voltage is

applied to the base of the inhibit gate (Q410) and to the base of channel B
tone amplifier Q407 via R420. Tone B can be amplified by Q407 only after
Q405 has saturated. This operation requires that Tones A and B be sent in
the proper sequence. Q405 will remain on for approximately one and a half
seconds after Tone A ends. During this period, Tone B may be amplified
by Q407 and detected by Q408 and Q409. However, no bias can be applied
to alert tone oscillator Q412 or squelch gate Q411 because the inhibit gate
(Q410) is zero-biased. When Q405 turns off, Q410, Q411, and Q412 turn
on and remain on until Tone B ends. The squelch gate (Q411) dc signal
turns the receiver audio on through squelch switch Q11 and the signal
from alert tone oscillator Q412 is fed to first audio amplifier Q12. The
alert tone is heard at the speaker.
In dual code models, the reception and detection of tones C and D are
identical to that of tones A and B in single-code models. Two single code
boards are cannected in parallel for dual-code capability (refer to Figure 5),
Voltage regulator Q406 insures that the decoder Supply voltage will
remain constant over variations in battery terminal voltage.
When the P-T switch is in the P position, CR407 of the talk-page
audio gate network is zero-biased by the voltage applied at point L\
and no audio path exists between points and (refer to Receiver
Schematic Diagram included herein). With the P-T switch in the T

5. SELECTIVE CALL CODE SELECTION AND TONE IDENTIFICATION
The Selective Call 'Handie-Talkie'' Radio is used in a two-tone
sequential signaling system. The first tone, designated tone A, is trans-
mitted for one second, The second tone, designated tone B, is transmitted
for three seconds. Each Selective Call 'Handie-Talkie" Radio in the system
responds to a unique combination of tones. This combination of tones is
determined by ''Vibrasponder" reeds installed in the 'Handie-Talkie'"' radio
(hereafter referred to as pager).
There are 60 unique tone frequencies from which Tones A and B
may be selected. Each tone is assigned a code number. This number is
usually referred to as the "Reed Code". For general code selection
information, refer to attached Chart PEPF-769.

1. General Encoding Method
a Ea ea ard
The following information is included for reference only and may not
apply to early Motorola paging systems. Use the appropriate encoder or ~
terminal instruction manual for detailed encoding instructions.
The relationship between the "pager code'' and the ''Vibrasponder"' reeds
installed is established by the general encoding method. One or two three-
digit code numbers are stamped on the code identification label. In single
code models only one code number will appear which is usually for indivi-
dual calling. In dual code models two code numbers will appear; one for
individual calling, and the other for group calling.
The 60 paging tone frequencies are divided into six groups of ten tones
each. These groups are numbered and designated Tone Group 1, Tone
Group 2, etc.. Table 2 shows the tone codes and frequencies.
The first digit of the three-digit pager code determines the groups
from which Tone A and Tone B will be selected. The tone groups indicated
for each first digit are shownin Table 1. The next two digits of the pager
code are the specific tones selected from the groups indicated in Table l,
for Tones A and B respectively.
To determine which tone frequencies or reed codes are associated
with a given pager code, proceed as follows: look up the first digit of the
pager code in Table 1. The groups for Tones A and B will be indicated.
Refer to Table 2 and, in the group shown in the previous table for Tone A,
the frequency and reed code for Tone A will be indicated on the line cor-
responding to the second digit of the pager code. The reed code and
frequency for Tone B, will be found in the group determined for Tone B,
on the line corresponding to the third digit of the pager code.
EXAMPLE TI: Pager 625 - According to Table 1, the first digit of this
pager (6) indicates that Tone A will be selected from Tone Group 2, and
Tone B will be selected from Tone Group 1. The second digit indicates
that tone 2 of group 2 will be used for Tone A, and the third digit shows
tone 5 of group 1 for Tone B. This unit will have the following reeds
installed:
Pager Code 625 -
Tone A - Reed Code 122, Frequency 634.5 Hz.
Tone B - Reed Code 115, Frequency 433.7 Hz.

TONE B (Group 1) Table 1
2-{[TONE 2 (Reed 122) Data

2. Code Type Assignment Encoding Method
This encoding method has been devised to accommodate the large
number of pagers used in high capacity paging systems such as the L08
Encoder or the L09 Dial Interconnected Paging Terminal. Pagers
encoded by this method are assigned a letter prefix. This prefix is the
"Code Type'' designation. In the general encoding method, the relationship
between the first digit of the pager code and the groups selected is arbitrary.
In the code assignment method, the selected groups depend on the system
code type. In essence, each code type column in this table is used in the
same way as Table 1 was used in the general encoding method. In the
column for the pager prefix, on the line corresponding to the first digit of
the pager code, will be located the tone groups from which Tones A and B
will be selected. Table 2 and the second and third digits of the pager code
will determine the exact reed codes as outlined in Paragraph l.

on the line corresponding to the third digit of the pager code.
EXAMPLE I: Pager 625 - According to Table 1, the first digit of this
pager (6) indicates that Tone A will be selected from Tone Group 2, and
Tone B will be selected from Tone Group 1. The second digit indicates
that tone 2 of group 2 will be used for Tone A, and the third digit shows
tone 5 of group 1 for Tone B. This unit will have the following reeds
installed:
Pager Code 625 -
Tone A - Reed Code 122, Frequency 634.5 Hz.
Tone B - Reed Code 115, Frequency 433.7 Hz.

2. Code Type Assignment Encoding Method
This encoding method has been devised to accommodate the large
number of pagers used in high capacity paging systems such as the L08
Encoder or the L09 Dial Interconnected Paging Terminal. Pagers
encoded by this method are assigned a letter prefix. This prefix is the
''Code Type'' designation. Inthe general encoding method, the relationship
between the first digit of the pager code and the groups selected is arbitrary.
In the code assignment method, the selected groups depend on the system
code type. In essence, each code type column in this table is used in the
same way as Table 1 was used in the general encoding method. In the
column for the pager prefix, on the line corresponding to the first digit of
the pager code, will be located the tone groups from which Tones A and B
will be selected. Table 2 and the second and third digits of the pager code
will determine the exact reed codes as outlined in Paragraph 1.
EXAMPLE II: Pager D476 would Rave the following reeds installed:
Tone A - Reed Code 117, Frequency 483.5 Hz.
Tone B - Reed Code 156, Frequency 767.4 Hz.

3. Alternate Receiver Coding
SE Sa dee aR ee ko
Dial interconnected paging terminals provide spare receivers to
substitute for regular pagers that are temporarily out of service. Spare
receivers are encoded so that they will not duplicate codes within the
system, yet will easily substitute for system pagers. Spare tones are used
for Tone A which are not part of any of the regular tone groups. Tone B
is selected from the regular tone groups. Alternate receiver codes always
have repeating second and third digits. The first digit of alternate pager
code determines both the spare tone to be used for Tone A, and the regular
tone group from which Tone B will be selected. The second or third digit
indicates the specific reed to be used for Tone B.
Two encoding methods are used for alternate receivers, a general
encoding method for medium capacity systems, and the code type assign-
ment method for high capacity systems. Generally, encoded alternate
pagers will have a three-digit code with no letter prefix. Code type
assignment alternate pager codes are prefixed with the system code type
letter. To find the reed assignments for an alternate pager, refer to the
applicable paragraph below.
(a) General Alternate Receiver Encoding Method
Look up the first digit of the alternate pager code in Table 4.
On the line corresponding to this digit, the tone A reed and the group
from which tone B will be selected are listed. Then look up the second
digit of the alternate pager code in Table 2. Refer to the group indicated
in the previous step for tone B.
EXAMPLE: Alternate pager code 366, refer to Table 4; first digit (3)
indicates reed code 130, frequency 979.9 Hz for tone A and tone B
selection from group 2. Refer to Table 2, the second digit (6) in Group
2 indicates reed code 126, frequency 788.5 Hz for tone B.
(b) Code Type Assignment Alternate Receiver Encoding Method
Alternate receivers in systems using this type of encoding have
pager codes prefixed with the system code type letter. The tone A reed
and group specified by the first digit of this pager code vary with the code
type letter. To obtain this information, refer to Table 6 in the code type
column specified by the letter prefix, selecting tone A from Table 5 and
Tone B as outlined in paragraph (a).
EXAMPLE III: Alternate pager B455; Refer to Table 6 in the code type
Brow. On first digit column 4, tone A reed code $20 and tone B selection
from tone Group 3 is indicated. In Table 2, on line 5, column 3, reed
code 160, frequency 953.7 Hz, is indicated for tone B.
SUMMARY: Alternate pager B455 has the following reeds installed.
i
Tone A = Reed Code S20, Frequency 1500 Hz.
Tone B = Reed Code 160, Frequency 953.7 Hz.
