Operation Manual

Appendix B - Troubleshooting
1. The transceiver will not power up.
A fuse may have blown or there is no voltage getting to the transceiver.
a) Check the power cable for cuts, breaks, or squashed sections.
b) After checking the wiring, replace the 7 Amp fuse.
c) Check the battery voltage. This must be greater than 10.5V.
2. The transceiver blows the fuse when the power is switched on.
The power wires may have been reversed.
a) Check that the red wire is connected to the positive battery terminal, and the black wire
is connected to the negative battery terminal.
3. The speaker makes popping or whining noises when the engine is running.
Electrical noise may be interfering with the transceiver.
a) Re-route the power cables away from the engine.
b) Add a noise suppressor to the power cable.
c) Use resistive spark plug wires and/or use an alternator whine filter.
4. No sound from the external speaker.
a) Check that the external speaker cable is physically connected.
b) Check the soldering of the external speaker cable.
5. Transmissions are always on low power, even when high (Hi) power is selected.
The antenna may be faulty.
a) Test the transceiver with a different antenna.
b) Have the antenna checked out.
6. Battery symbol is displayed.
The power supply is too low.
a) Check the battery voltage. This should be at least 10.5 V ± 0.5 V DC.
b) Check the alternator on the vessel.
7. GPS alarm sounds and LCD shows: Please check GPS link! The NO GPS symbol is
shown.
GPS data has been lost. This sequence will repeat every 4 hours until GPS data from an opera-
tional GPS receiver is available. The GPS cable may faulty or the GPS setting may be incorrect:
a) Manually enter your position and UTC time data (see Section 3.6.1)
b) Check that the GPS cable is physically connected.
c) Check the polarity of the GPS cable.
d) Check the baud rate setting of the GPS if applicable. The baud rate setting should be
4800. Parity should be set to NONE.
