Duplex operation

(U.S.A. version only)

The duplex function allows you to call a flight service station while receiving a VOR station. The duplex function requires frequency programming for the flight service station in ad- vance.

DProgramming a duplex frequency

qPush [CLR•DEL] to select the frequency mode.

wSet a NAV band frequency using the tuning dial or keypad.

• NAV band frequency range: 108.00–117.975 MHz

ePush , then push [5•DUP-W].

• “DUP” flashes and transmit frequency appears.

rSet the frequency of the flight service station using the tun- ing dial or keypad. When using the tuning dial, push [ENT•WX] after setting a frequency.

• The displayed frequency returns to the NAV band frequency.

DOperating the duplex function

qSet the desired frequency in NAV band.

• NAV band frequency range: 108.00–117.975 MHz

wPush , then push [6•DUP] to turn the duplex function ON.

• “DUP” appears on the function display.

ePush and hold [PTT] to transmit at the pre-programmed

transmit frequency.

r Release [PTT] to return to receive.

tPush , then push [6•DUP] to cancel the function.

• “DUP” disappears on the function display.

NOTE: A duplex frequency can be programmed into each memory channel independently. Set a duplex frequency before programming the memory channel, if desired. The duplex ON/OFF setting can also be programmed into a memory channel.

EXAMPLE: Programming 123.65 MHz as the transmit frequency in the duplex function.
