PMA7000B Pilot Guide

R6 202-780-0001

The lower buttons control which transceiver is selected for transmit.

The PMA7000B gives priority to the pilot’s PTT. If the copilot it transmit-

ting, and the pilot presses his PTT, the pilot’s microphone will be heard

over the selected com transmitter.

The PMA7000B-Series has an automatic selector mode. Audio from the

selected transceiver is automatically heard in the headsets and speaker (if

selected). You can check this function by switching from C

OM 1 to COM 2

and watch the selected audio light on the selector change from COM 1 to

COM 2. This ensures the pilot will always hear the audio from the trans-

ceiver he is transmitting on.

When switching from

OM 1 to COM 2, while

OM 2 audio had been

selected, Com 1 audio

will continue to be

heard. This eliminates

the pilot having to

switch Com 1 audio

back on, if desired.

When switching from C

OM 1 to COM 2 while Com 2 has NOT been se-

lected, Com 1 audio will be switched off. In essence, switching the mic

selector will not effect the selection of Com receiver audio.

When the duplex, or TELEPHONE mode is implemented, Com 3 becomes

the “TEL” position. See page 8 for complete information.

NOTE: Selecting COM 3 –TEL– mode will disable pilot and copilot inter-

com, as the intercom circuit is transferred to the telephone use.

Swap Mode (Switch from Com 1 to Com 2 remotely)

With a yoke mounted, momentary switch, the pilot can change from the

current Com transceiver (Com 1 or 2) to the other by depressing this

switch. To cancel "Swap Mode," the pilot may either press the yoke

mounted switch again, or select a different Com with the XMT buttons.

Audio Selector (All models)

Receiver audio is selected through seven momentary, push-button, backlit

switches. You will always

hear the audio from the transceiver that is se-

lected for transmit.

The users can identify which receivers are selected by noting which of the

green switch LEDs are illuminated. Push buttons labeled Nav 1, Nav 2,

MKR (Marker), AUX (auxiliary), and SPR (Speaker) are "momentary type

switches. When one of these buttons is pressed, be active, and the LED will

illuminate. Press the switch again and it be in the "off" position and remove

that receiver from the audio.
