Configuring Music Input With Function Keys; Playback Button Installation; Marker Beacon Installation; Marker Antenna Installation - Honeywell Bendix/King KMA 30 Manual

Press the Mute switch to activate the four Karaoke modes (disabling crew SoftMute™). Turning down the
entertainment volume allows the pilot to place the entertainment into the background while having the
radios in the foreground and eliminates the constant interruption of the music while still keeping the ra-
dios a priority.
Local oscillators and internal signals from entertainment equipment can cause undesired interference with
other aircraft systems. Before takeoff, operate the entertainment devices to determine if there is any ad-
verse effect within the aircraft systems. If any unusual operation is noted in flight, immediately switch off
the entertainment devices.
All additional entertainment devices must be switched off for both takeoff and landing.
2.5.2.1 Entertainment 2 Mute (J2 Pin 13 & 14)
Connecting J2 pin 13 to pin 14 (or ground) through a SPST switch places the entertainment #2 music
source into the Karaoke Mode. In this mode, incoming music and intercom conversation will not mute the
music for the passengers' intercom net. This allows uninterrupted music during casual conversation and
at times when radio communications are of lesser importance.
If desired, the AUX button can act as the passengers' mute control. Connect J2 pin 18 (AUX logic) to J2
pin 13 (Entertainment. 2 Mute inhibit). Then, Entertainment 2 will not mute when the AUX button is on.
(Not recommended if DME is input is used.)
2.5.3

Configuring Music Input with Function Keys

The music inputs can be configured by the user from the front panel (see section 3.10). There are three
configurations available, independent, ICS mode dependent, and single input (music 1 to all stations).
If the inputs are independent, Input #1 (or the front jack) is provided to the pilot and copilot. Muting
(SoftMute™) is controlled by the front panel "mute" button. Music 2 is provided to the passengers at all
times, with muting controlled by an external switch (see § 2.5.2.1).
If the inputs are intercom mode dependent, input 1 goes to the pilot, copilot, and all passengers when the
intercom is in the "ALL" mode. In "ISO" mode, the copilot and passengers will hear music input 1. Music
2 is ONLY active in CREW mode, and then provided only to the passengers. The externally switched pas-
senger SoftMute™ control becomes active in CREW.
If the single-source mode is activated through the function keys, the front panel jack (and music 1) is con-
nected to all intercom positions, regardless of the intercom mode. Crew muting is controlled by the front
panel, passenger muting controlled through the switch. See section 3.11 for more details.
2.5.3.1 Annunciation and recorder playback
The pilot and copilot can hear the Function Key annunciations. If the customer wants to exclude playback
and function key annunciation playback from the copilot position, contact Bendix/King for more informa-
tion.
2.5.4

Playback button Installation

Internal Recorder can be played back from the front panel. A remote momentary, normally open (NO)
push button switch may be installed if desired to remotely activate the Recording System playback. This
switch can be located anywhere in cockpit convenient to the pilot's reach. The NO switch should be con-
nected to pin 22 of J2 of the KMA 30, and ground. When installed, this button will act as in § 3.13.
