1.2 Power Switch (EMG-Fail Safe Operation)

Unit power is turned on and off by pushing the volume knob. In the

OFF or

"EMG" position, the pilot is connected directly to Com 1. This allows communication capability regardless of unit condition. Any time power is removed or

OFF, the audio selector will be placed in the fail-safe mode.

turned

The power for the CD player (CD-15) is controlled by the audio panel. When the audio panel is on, it automatically activates the player. If it is necessary to disable the CD player, hold the two CD buttons (far right) in for more than 2 seconds. This removes power from the CD-15 circuits. To re-enable the CD-15, cycle power on the SL15-CD audio panel.

The power switch also controls the audio selector panel functions, intercom, CD player and marker beacon receiver.

1.3 Microphone (XMT) Selection (All models)

There are six pushbuttons associated with the communications transceivers. The lower buttons control which transceiver is selected for transmit.

The SL15-CD gives priority to the pilot’s PTT. If the copilot is transmitting, and the pilot presses his PTT, the pilot’s microphone will be heard over the selected communications trans-

mitter.

The SL15-CD has an automatic selector mode. Audio from the selected transceiver is automatically heard in the headsets and speaker (if SPR 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 transceiver he is transmitting on.

When switching from C

OM 1 to COM 2, while COM 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 selected,

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. This is the pilot’s “hook” switch, when the system is interfaced to an appropriate approved wireless telecommunication system, such as the AirCell system. Placing the mic selector in Com 3 places the pilot microphone and headphones on the cellphone. The pilot PTT will switch the pilot mic to the other selected com transceiver, and allow continued aircraft communications as well. The copilot will also be able to transmit with his PTT as well.

NOTE

Placing the mic selector switch in the COM 3 –TEL– mode will disable pilot and copilot intercom, as the intercom circuit is transferred to the telephone use. In crew or ISO mode, placing the switch in TEL mode removes the passengers access to the telephone.

1.3.1 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.
