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 terminals open or 
misaligned.

Visually inspect the battery terminals 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 terminals 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. 

2. Telephone exhibits poor reception or 
erratic operation such as calls frequently 
dropping or weak or distorted audio.

a) Antenna assembly defective.

Check to make sure that the antenna terminal 
makes proper contact with the transceiver board 
assembly. If connected properly, substitute a 
known good antenna. If the fault is still present, 
proceed to b.

b) Transceiver board assembly 
defective.

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.

3. Display is erratic, or provides partial or 
no display.

Transceiver board assembly defective. 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.

 4. Incoming call alert transducer audio 
distorted or volume is too low.

a) Defective alert transducer.

Replace alert transducer according to the 
procedures. If fault still present, proceed to b.

b) Faulty transceiver board assembly.  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.

5. Telephone transmit audio is weak. 
(usually indicated by called parties 
complaining of difficulty in hearing voice).

a) Microphone misaligned or 
defective.

Ensure microphone is correctly positioned in 
socket. If fault still present, replace the 
microphone as described in the procedures. If 
fault is not cleared, proceed to b.

b) Transceiver board assembly 
defective.

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.

6. Receive audio from earpiece speaker is 
weak or distorted.

a) Earpiece speaker defective. 

Temporarily replace the LCD speaker assembly 
with a known good assembly. Ensure good 
connection. Place a call and verify improvement 
in earpiece audio. If fault is cleared, reassemble 
the phone with the good assembly. If fault is not 
cleared, proceed to b.
