System Configuration/Checkout 4.4.2 Audio Output (for GDL 69A connected to MX20 or GDU 104x) CAUTION If GDL 69A is connected to an audio panel, the music input should be used. A test must be conducted to ensure COMM radio signals will mute audio output from the GDL 69A. NOTE If a GDL 69A is installed with the 400/500 series, the GDL 69A audio feature is not operational. Verify Channel 0 or other channel is displayed. The GDL 69A powers up with the audio muted. Press mute or volume keys (switch or on display/control device). Verify sound output from speakers. The GDL 69A may come with a trial activation to XM audio entertainment. With this trial activation, all audio channels for the given subscription should be available. 4.4.3 Discrete Switches (for GDL 69A only, if installed) Channel Up/Down- Press the Channel Up or Down switches and observe that channel display on the display/control device increments or decrements, respectively. Volume Up/Down- Press the Volume Up or Down switches and observe that speaker volume increases or decreases, respectively. Mute-Pressing the Mute switch should terminate sound from speakers. Pressing it again should resume audio. More optional checkout procedures are available after the GDL 69/69A is activated with XM Satellite Radio Corporation. Refer to the XM Activation Procedure document, P/N 190-00355-04. 4.4.4 Audio Suppression Input (GDL 69A only) The GDL 69A has audio suppression inputs to disable the audio output when an electronic aural warning, such as a stall warning or gear warning, is activated. With installations where the Audio Suppression is used, activate the Stall Warning, Gear Warning, or other interfaced inputs to the Audio Suppression inputs, one at a time. Verify the GDL 69A audio to the crew headphones is muted when each warning alarm is activated. The stall warning horn may be activated by simply raising the stall vane on the leading edge of the wing. The gear warning horn may be simulated by providing power or ground, as appropriate, directly to the horn. This can only be done provided the horn has been tested for proper operation when a gear retraction test was performed. 4.5 Activation with XM Satellite Radio Before the GDL 69/69A can be used, the unit has to be activated by XM Satellite Radio and services have to be subscribed to XM Satellite Radio Corporation.
