Audio/Radio Management Audio/Radio Management AR 1. Introduction This appendix describes the EFIS pages for Audio/Radio control for a typical customer interface configuration. One GDR-XXX radio would be represented by the display lines labeled COM1, NAV1, UHF, and MKR when if all features were enabled.
Audio/Radio Management Figure AR-1: Audio Radio Page Format AR 2.1. Audio/Radio System Colors WHITE for items set by pilot and held by the EFIS or items where device feedback is not expected, such as STBY frequency/codes, TX indicator when there is no TX feedback, or marker beacon receiver high/low sensitivity modes. In low-light conditions, light gray is used for analog bar indication. CYAN (light cyan for visibility) for information received from the device unrelated to a pilot setting, e.g.
Audio/Radio Management AMBER (YELLOW) only for stuck microphone and DME hold, which require immediate pilot awareness. RED for items requiring immediate pilot action. Only used to indicate a device failure (red “X”). GRAY for device name and selection box around selected device line. Light gray for devices that do not confirm their attribute setting. AR 3. Common Symbols Some symbols are common for different lines of the AR page.
Audio/Radio Management Table AR-2: Line Symbols Symbol Meaning Notes Reporting an active position identification (IDENT) Actively receiving device Test mode confirmed If device is not reporting active position identification but is reporting an active reply to an ATC interrogation Magenta when in squelch test mode Decoded station Displays up to five characters identifier in light cyan Name of device being controlled Magenta when device is set as the following: BFO = BFO mode Mode confirmed TST = Test
Audio/Radio Management Table AR-4: Level Bar Symbol Meaning Notes was pushed to adjust the volume and turned down to lowest setting Muted volume Range of attribute at 50% Device does not confirm setting Volume level NOTE: When an audio controller fails, the line for the intercom is displayed as shown in Figure AR-1. However, failure of the audio controller may cascade across other devices.

Encoder Labeling When a selected device line is enabled for frequency, code, mode or level adjustment, an indication of the value to be changed by the encoder appears. On the AR menu or expanded menu, a colored rectangle is drawn around the value, which is changed by the encoder when the line is selected.
Audio/Radio Management The final line after the last AR device, DONE appears in the AR menu. Figure AR-9: DONE Shortcut 1st Ed Oct, 2017 IDU-680 EFIS Software Version 8.
Audio/Radio Management AR 3.8. AR Menu Options E X I T TOP AREA U S E R Allow setting the STBY Transponder code to a User code S M A R T M U T E “MUTE” or “UNMUTE” for all audio devices other than the active transmit enabled one and ATC.
Audio/Radio Management device at a time can be selected.) Enabling transmission automatically unmutes the associated transceiver and disables transmitting on any other transmitter. If the audio controller fails, button appearance and operations are inhibited. 3) HOLD (L5): When selected line is a VHF NAV receiver, toggles DME hold function for the DME channel tuned with the selected navigation receiver.
Audio/Radio Management 10) MUTE, UNMUTE (R6): When audio controller not failed, toggles muting for the device. If audio controller fails, button appearance and operation are not inhibited. 11) SWAP (R7): When selected line is a device with ACTV and STBY frequencies, channels, or codes, toggles the ACTV and STBY frequencies, channels, or codes. If device fails, appearance and operation are inhibited. 12) SPLIT TX (R7): When selected line is an intercom, toggles the split transmit mode.
Audio/Radio Management 18) (): When selected line is an ADF receiver, scroll to increase or decrease STBY frequency within the frequency range of the ADF receiver on a per-digit basis. Push to change the selected digit. If selected ADF receiver fails, encoder appearance and operation are inhibited. 19) (): When selected line is a transponder, scroll to increase or decrease STBY 4-digit code on a per-digit basis. Push to change the selected digit.
Audio/Radio Management B A C K E X I T TOP AREA U S E R Allow setting the STBY Transponder code to a User code COM: “TX” NAV: “HOLD” ATC: “VFR” COM: “EMERG” ATC: “EMERG” BOTTOM AREA “MUTE” for all audio-controlled devices other than the active transmit enabled device.
Audio/Radio Management 3) HOLD (L5): When expanded menu is for a VHF NAV receiver and first line is selected, has same function as described in § AR 3.8. 4) VFR (L5): When expanded menu is for a transponder, has same function as described in § AR 3.8. 5) IDENT (L8): When transponder is not in a failed state, enables IDENT feature of the transponder. Button appearance and operation are independent from the selected line.
Audio/Radio Management AR 3.9.1. ADR7050 COM Transceiver Figure AR-12: ADR7050 COM Transceiver NOTE: When is in SLCT mode for this device and applicable line is selected, scroll CW to increase or CCW to decrease squelch, sidetone mic gain, mic threshold, or channel selection options.
