Maintenance and Troubleshooting
Due to its rugged design, your radio requires very little maintenance.
However, it is a precision electronic instrument, so you should follow a few
precautions:
• If the antenna has been damaged, do not transmit except in an emergency
situation. Transmitting with a defective antenna may cause further radio
damage.
