· MIC/MASK − When selected in, the headset microphone is available. When selected out,
the mask microphone is available and intercom audio is connected to the speaker
(regardless of the position of the SPKR switch).
· INT − Adjusts the intercom headset audio level. When selected out, the audio panel is
connected to other audio control panel(s) and to external audio jacks.
· ID/BOTH/VOICE − “ID” − Allows only NAV tone ident to be heard . “VOICE” − Allows only
VOICE audio on NAV frequency to be heard. “BOTH” − allows voice and ID to be heard
simultaneously .
Speaker/Headphone
· Speaker − Adjusts the audio level of the flight compartment speakers.
· ST switch − Sidetone switch adjusts the speaker audio level in transmit. Turns the speakers
ON/OFF unless oxygen mask is in use.
· MKR/MUTE − Marker beacon controls onside
receiver sensitivity. Mute silences the marker
beacon audio. Rotating MUTE selects HI or LO SENSitivity.
· H’MIC − Button selected out, interphone functions operate in hot mic mode. Button selected
in, connects microphone to the interphone PTT function.
· Headphone − Adjusts the audio level of headphone (master volume control).

RADIO COMMUNICATION SYSTEM
The capability for controlling the operating modes, frequencies and codes can be accomplished by
using the Radio Management Unit (RMU) which is the central control unit for the entire radio system.
The RMU controls all of the VHF COM tuning functions and allows emergency tuning by the FMS.
When an FMS tunes the radios, the digital signals from the FMS enter the system where they act in
much the same manner as if the RMU tuning knob was being operated. This will allow the FMS to
enter into the system in an organized manner. For FMS operation, refer to Pilot’s Operating Manual
Pub No A28114618500.
The audio section of the VHF COM provides SELCAL outputs used for airplane addressing by
transmitting tones across a VHF COM channel.
VHF 1 and 2 Communications Systems
Two separate, but identical, narrow band width VHF communications systems (VHF 1, VHF 2)
which can be operated separately or simultaneously, are provided. These systems are used to
provide AM voice communication between the airplane and a ground station and/or another
airplane. Frequency tuning and mode selection is by CRT pages and controls on the RMU.
The integrated communications units with transceivers (located in the forward fuselage avionics
bay) provide VHF communication (VHF COM) and Mode S Transponder data link capabilities. The
communication transceiver tuning range is as follows:
System Frequency Range Channel Spacing
VHF 1 and 2 118.00 to 151.975 MHz 8.33 kHz
VHF 3 Communications System
The VHF 3 is located in the forward fuselage avionics bay and is used primarily as a data radio. It
does not have an ATC transponder but has the capability of operating in the data mode as well as
the voice mode.
The RMU automatically senses when the third VHF COM radio is installed and adds a menu
selection to the MENU page. Control of frequency and operating mode is performed by the RMU
and FMS CDU. VHF COM 3 works in conjunction with the Data Link System as the data radio. The
communication transceiver tuning range is as follows:
System Frequency Range Channel Spacing
VHF 3 118.00 to 151.975 MHz 8.33 kHz

INTEGRATED RADIO SYSTEM
The radio communications unit provides VHF communication (VHF COM) and Mode S Transponder
data link capabilities. It interfaces with the FMS, SELCAL, TCAS, HF, audio control panels and is
controllable from either RMU.
