Air Test allows the testing of any combination of ten frequency pairs, two transmitter power levels, six modu-
lation modes, and three receiver squelch modes. Selection of a frequency pair is done by rotating the rotary
selector switch on top of the radio. See Table 1 for a listing of the Air Test transmit and receiver frequencies, and
transmitter power output levels associated with the rotary selector switch.
To change modulation/squelch modes, press one of the "side button" switches on the side of the radio: press-
ing the button closest to the front of the radio (SB1) will increment the mode; pressing the button closest to the
back of the radio (SB2) will decrement the mode. See Table 2 for a listing on the various modulation/squelch
modes.
As the modulation/squelch mode is changed, a one- to six-"bonk" audio tone will be heard, and the display
will indicate the mode by displaying the squelch mode number from one to six.
