MAINTENANCE & 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.
• You are responsible for continued FCC technical compliance of your radio.
• You should arrange for periodic performance checks with your PRESIDENT
dealer.
