Radio Care
The following are suggestions to assist you in troubleshooting possible operating problems.
CAUTION:
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.
If your radio is locked up or the display shows FAIL 01/09, 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.
