Table 5. V150 Telephone: Level 1 and 2 Troubleshooting Chart
SYMPTOM
PROBABLE CAUSE
VERIFICATION AND REMEDY
1. Telephone will not turn on or stay on.
a) Battery either discharged or
defective.
Measure battery voltage across a 50 ohm (>1
Watt) load. If the battery voltage is <3.25 Vdc,
recharge the battery using the appropriate
battery charger. If the battery will not recharge,
replace the battery. If battery is not at fault,
proceed to b.
b) Battery connectors open or
misaligned.
Visually inspect the battery connectors on both
the battery and the telephone. Realign and, if
necessary, either replace the battery or refer to
a Level 3 Service Center for the battery
connector replacement. If battery connectors
are not at fault, proceed to c.
c) Transceiver board assembly
defective.
Remove the transceiver board assembly.
Substitute a known good assembly and
temporarily reassemble the unit. Depress the
PWR button; if unit turns on and stays on,
disconnect the dc power source and reassemble
the telephone with the new transceiver board
assembly. Verify that the fault has been cleared.
If the fault has not been cleared then proceed to
d.
d) Keypad board assembly failure.
Replace the keypad board assembly.
Temporarily connect a +3.6 Vdc supply to the
battery connectors. Depress the PWR button. If
unit turns on and stays on, disconnect the dc
power source and reassemble with the new
keypad board. If the fault is not cleared then
proceed to e.
e) Front housing assembly failure.
Disassemble unit and insert the transceiver
board assembly into new front housing
assembly. Insert a battery and depress PWR
button. Ensure unit stays on. If fault has been
cleared, reassemble unit in new front housing
assembly.
