Troubleshooting
The following are suggestions to assist you in troubleshooting 
possible operating problems.
If your radio is locked up or the display shows 
FL 01/90
 (W4, W5, 
W7) or 
FAIL 01/90
 (W9), turn the radio off and then back on. If this 
does not correct the condition, take the radio to a qualified radio 
technician for service.
If radio operation is intermittent, check with other persons using the 
system for similar problems before taking the radio in for service. 
Similar problems indicate a system malfunction rather than a radio 
failure.
If symptoms persist or, if your unit exhibits other problems, contact a 
qualified radio technician.
The cables that connect to the rear of 
the radio could have live voltage on 
some of their pins. Do not remove or 
reconnect these cables. Only a 
qualified radio technician should 
perform this task. Service performed 
by unauthorized personnel may cause 
the radio to transmit an emergency 
alarm even if the unit is turned off.
