PART 1
1. Basic Rules
1.1 Status at Start Up
Each time you tum the FM-8000 on it performs a
self-test to check for proper operation. After the self-test
is completed, the unit starts up with the previous
settings of the folio wing Controls:
• Channel mode
• Channel number
• Output power
• Speaker on/off
• Dimmer
If the self-test detects equipment fault, error indications
appear. For description and meaning of error indications,
see page 3-3 in PART2.
When the FM-8000 is tumed on it powers the DSC-8V
(if connected).
NOTE: When the power is tumed off while
transmitting, scanning or dual watching, the last settings
for the above-mentioned Controls are not memorized.
1.2 Key Operation Rules
Key input When entering a line of data, press each key within 5
seconds of previous key. Otherwise, the FM-8000 will
return control to the previous display screen.
SHIFT key The SHIFT key altemates selection of primary and
secondary functions. “SHIFT” appears on the LCD
when the SHIFT key is pressed. You can select a
secondary function while “SHIFT”’ is displayed, up to 5
seconds after pressing the key.

1.4 Key Response Beep
One short beep One short beep sounds to confirm acceptance of key
input.
Three Short beeps Three short beeps sound to indicate invalid key input or
to inform the activation of time-out timer.
1.5 Remote Control
“REMOTE”
indication
• When the remote station RB-700 or the DSC
Terminal DSC-8V (if connected) is in operation, the
indication “REMOTE” appears on the LCD of the
FM-8000.
• Suppose that the FM-8000 has higher priority than
the RB-700. When the handset of the RB-700 is
picked up with the handset of the FM-8000 also
picked up, the indication “REMOTE” on the
FM-8000 blinks.

When you turn on the FM-8000, it automatically
conducts a self-test to check for proper operation.
ContentS The devices checked in this self-test are:
• Transmitter PLL
• Receiver PLL
• ROM in the CPU
• RAM in the CPU, and
• E 2 PROM.
Starting Tum the power on.
Result When the self-test is completed, the FM-8000 is ready
for operation. If equipment fault is found, error
indications appear on the LCD. Refer to page 3-3 in

2. Maintenance
2.1 Regular Check
Introduction The FM-8000 is designed and constructed to give the
user many years of trouble-ffee performance. However,
no machine can perform to the utmost of its ability
without regular maintenance. For better performance:
• Have a licensed radiotelephone technician check the
transceiver and antenna before initial operation and
once annually to ensure compliance with pertinent
regulations.
• A quarterly routine maintenance program should be
established and should include at least the following:
Item
Check Point
Connectors
& Cables
Check all connectors (antenna, power, handset, ground, etc.),
cables and wires for proper seating, foreign material and
corrosion. Wipe off any foreign material with a clean cloth.
Replace wom parts. Carefully inspect the coaxial cable
connected between the antenna and the transceiver for
extemal damage.
Transceiver
Accumulated dust or dirt on the exterior surface and
keyboard can be removed with a clean, soft cloth. Clean the
LCD with lens tissue or soft cloth to prevent scratching. Do
not use Chemical solvents to clean the transceiver. They
may harm plastic, paint and markings.
Antenna
Inspect the antenna insulators for corrosion. Check condition
of soldered connections. Remove salt deposits with fresh
water.
Power
Supply
The FM-8000 is powered by 24VDC +30%, -10% power.
Confirm that the power supply is operating within this rating.
Check battery terminals and ship’s mains switchboard for
proper seating and corrosion.
Fuses
Fuse holders are subject to corrosion which increases circuit
resistance. Fuses should be removed from their holders,
inspected, and cleaned of any accumulation of dirt or
corrosion.
PART 2
3. Troubleshooting
3.1 Troubleshooting List
Introduction The cause of most VHF operating problems is the
antenna/antenna feeder or power supply, so those are
the first places to check if there is trouble.

4. Replacement of Fuse
Introduction
A CAUTION
Use the correct fuse.
Use of the wrong fuse can cause fire or
equipment damage.
To protect the unit from reverse polarity and equipment
fault, two 10A fuses are provided in snap-in holders on
the power cable. If a fuse blows, find the cause of the
problem before replacing it. Never use a fuse rated
more than 10A since it may cause serious damage
to the equipment.
