All audio, except the S/T of the radio in use and the DIRECT AUDIO input signal, is muted during transmit
for clarity. ICS operation allows transmit during any ICS mode by using the transmit PTT switch.
All switches, relay contacts and external connections are gold plated for maximum reliability. Switches
and replays are sealed. G10-FR flame retardant circuit boards are postcoated for maximum moisture
resistance and corrosion prevention. Relays are sealed, high vibration rated (50 g shock), dry nitrogen
filled units.
