Problem Probable Cause / Solution
Radio cannot be switched on. 1. Poor connection to power supply / battery.
(Check connections.)
2. Fuse blown. (Inspect wires and fuse.)
No sound from radio. 1. Volume control set too low. (Rotate
volume control clockwise).
2. Squelch level too high. (Back off squelch –
rotate squelch control anticlockwise.)
3. Water in front of speaker. (Drain water.)
The radio performs a series of self tests when power is first switched on.
The mode-indicator and keyboard LEDs, plus LCD backlight, are cycled, and the
LCD display contrast settings are briefly exercised. During this sequence, internal
self tests (such as synthesiser lock and memory integrity) are performed and the
LCD display shows a progress bar during the test sequence. If errors are detected
the radio will display an error screen. Possible error screens are shown here, each
with an explanation.

Type of Test / Error Message Probable Cause / Solution
This may be caused by a checksum error or
other internal fault. (If the error is still present
after the radio is switched off and on again,
then it will be necessary to consult a Service
Agent, because the radio may be using
incorrect information, and may try to operate
outside its design limits.)
When the radio switches on, it tries to find a
source of GPS derived positional
information, via the NMEA port, and the
display message is ‘Search for Position’. If
no position information is detected within 2
minutes, the display message is ‘Pos update
not found’.
Radio synthesiser lock could not be
confirmed. Operation of the radio is
inhibited.
(If the fault persists after the radio is
switched off and on again, then it will be
necessary to consult a Service Agent.)
A fault was found when checking data in the
processor registers.
Operation of the radio is inhibited.
(If the fault persists after the radio is
switched off and on again, then it will be
necessary to consult a Service Agent.)
