10. Internal Charger not working. a) Faulty charger circuit on transceiver
board assembly.
Test a selection of batteries in the rear pocket of
the desktop charger. Check LED display for the
charging indications. If these are charging
properly, then the internal charger is at fault.
Replace the transceiver board assembly (refer
to 1c). Verify that the fault has been cleared and
reassemble the unit with the new transceiver
board assembly.

standard battery is removed.
Lithium button cell in the front housing
assembly may be depleted.
Remove the transceiver board assembly from
the front housing assembly and insert into
known good front housing assembly. Ensure
good flex connection. Check RTC time does not
reset. If fault is cleared, rebuild with new front
housing assembly. If fault is still present, restore
original front housing assembly.
12. No or weak audio when using headset. a) Headset not fully pushed home. Ensure the headset plug is fully seated in the
jack socket.
b) Faulty jack socket on transceiver
board assembly.
