ASTRO XTL 1500 Digital Mobile Radio with Control Head 77
Troubleshooting
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, 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.
