Selecting the Receiver Mode

One of three receiver modes may be selected using the Receive Mode Select

(MODE) key. The modes are Main, Both, and ADF.

Transmitting and Receiving on the displayed channel is enabled when

Main

the MN annunciator is illuminated.

Scanning of both the Guard and Main receiver frequencies. When the

Both

receiver detects a signal on either frequency, scanning stops on the

active channel. The annunciator associated with that frequency is

displayed. Transmitting while in the Both mode is accomplished on the

Main frequency. Scanning resumes when the active frequency becomes

idle.

This is available if the ADF option was enabled during installation. When

ADF

the ADF mode is enabled and active, the MN annunciator is illuminated

and the letters AdF appear in the frequency display when preset channel

mode is active or in the channel display when manual frequency mode is

in use. The transmitter is disabled and an independent ADF receiver will

be enabled.

Transmitting

Note:

Transmitting is disabled when the ADF receiver mode is selected or when

in the programming mode. Voice communications are disabled while in

the X-Mode.

For normal voice communications, the transmitter is keyed by pressing the micro-

phone PTT button or through the aircraft radio/audio control system, the TX

annunciator will be illuminated. For transmitting digital data, refer to the X-Mode

section.

A transmitter test is available that modulates the carrier with a 1kHz tone. This is

activated by pressing and holding the PUSH TONE button. When this button is

pressed, the TX annunciator will be illuminated.

Entering a Manual Frequency

The CHAN button is used to switch the radio between manual and preset channel

selection. When a frequency is selected manually, the receive and transmit fre-

quencies are the same. To enter a frequency manually, perform the following

steps:

•

Momentarily press the CHAN button to select the Manual Frequency

Mode (top display line is blank).

•

Rotate the small Frequency/Channel Select Knob to change the

frequency in 25 kHz steps. Clockwise rotations increase while counter-

clockwise rotations decrease the displayed frequency.

Rotate the large Frequency/Channel Select Knob to change the

frequency in 1 MHz steps. Clockwise rotations increase while counter-

clockwise rotations decrease the displayed frequency.
