Maintain a minimum distance of 20cm (or up to 142cm depending on specific model documentation) from the antenna during operation to avoid exceeding safety limits.
To guarantee reliable long-term operation, enforce the standard ambient limits during regular vessel surveys: Operational Limit Diagnostic Action 21.6V to 31.2V Max Measure under full 40A TX load.

The synthesizer generates the ultra-stable local oscillator frequencies required for exact channel locks. Misalignment here leads to frequency drifting or an absolute failure to receive and transmit on standard marine channels. Power Amplifier (PA) & Filter Module Maintain a minimum distance of 20cm (or up

Verify that the external AC plug or DC battery bank reads within acceptable limits.
If you are not a licensed radio technician, proceed with extreme caution. Here are five golden rules when using the :
