When the desired channel is indicted in the standby display it may be placed into the active position by depressing the “Flip-flop” button located to the left of the displays (labeled COMM and NAV); the active channel is then placed into the standby position.  The NAV receiver features a VC / ID button to permit selection of the voice or identification reception. In the Ident condition a ‘Tic’ is displayed on the active NAV channel display.  The COMM transceiver features a test button which overrides the squelch to verify proper receiver operation and to allow reception of weak signals. Also provided on the active COMM display is a ‘Tic’ to indicate transmitter power output.  The adjustment hole by the MHz switch permits operator adjustment of the display dimmer range for optimum nighttime brightness.  The adjustment hole by the KHz switch permits squelch adjustment and has a range of 10db.
