PROBLEM: 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 10A
fuse (one spare fuse is supplied).
c) Check the battery voltage. This must be at
least 10.8V ± 0.5V DC.
PROBLEM: 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.
PROBLEM: 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.
PROBLEM: 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.
PROBLEM: 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.
PROBLEM: Battery symbol is displayed.
The power supply is too low or too high.
a) Check the battery voltage. This should be at
least 10.8V ± 0.5V DC.
b) Check the alternator on the vessel.
PROBLEM:
No position information is
displayed.
The GPS cable may faulty or the GPS setting
may be incorrect.
a) Check that the GPS cable is physically
connected.
b) Check the polarity of the GPS cable.
c) Check the baud rate setting of the GPS if
applicable. The baud rate setting should
be 4800 for NMEA. Parity should be set to
NONE.
