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.)
Radio will not scan (scan program
selected and running)
1. The squelch level may be set incorrectly
for operation of scanning function. If the
squelch level is too low (control too far
counter-clockwise), scanning will halt. If
the squelch level is too high (control too far
clockwise), weak signals may not be
heard.
No sound heard from speaker 1. If, after setting volume and squelch
appropriately, sound still cannot be heard
then the internal speaker may be disabled.
(The transceiver is supplied with the
internal speaker enabled.) To re-enable
the speaker, go to Profiles -> Speaker
settings.
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.
Power-Up Self-Tests (1)
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.)
