Multi-Function (XMIT / ICS) Switch Operation
Note
: At installation, this switch may be configured to operate in default or alternative mode. Check with your
installing agency for confirmation of the operation of this switch.
Default Operation
When in the default XMIT/ICS configuration, this switch acts as the pilot’s ‘Press-to-talk (PTT) button. The unit will
transmit on the selected transceiver when the switch is set to the ‘up’ position, and when set to the ‘down’ position, it
will transmit on the intercom.
Alternative Operation
This switch may be configured to provide a ground signal to operate other equipment.
3.3.8
Music Operation
Music to the phones will be muted by incoming audio (ICS, Receive, Direct or Alert Audio) or if the unit is transmitting.
When the incoming audio has ended, the music will gradually return to the previous level.

Emergency Operation Mode
Emergency mode can be selected by the Mode switch on the front panel, or entered automatically if power to the unit
is lost.
3.4.1
Auto Emergency Mode
If the unit is in emergency mode because power has been lost to the unit, the sum of the COM 1 transceiver, NAV 1
receive, and DIRECT AUDIO will be routed to the pilot’s phones and the CVR. The pilot's microphone and transmit
key are connected to the COM 1 transceiver. No other function in the JA95 will operate when power is lost. All
indicator LEDs, legends and annunciators will be dark.
3.4.2
Selected Emergency Mode
If the unit is in emergency mode because the EMER / NORM switch is in the EMER position and sufficient power is
applied to the JA95, the sum of the COM 1 receive, NAV 1 receive, DIRECT AUDIO and Alert audio will be routed to
the pilot’s phones and the CVR. The pilot's microphone and transmit key are connected to the COM 1 transceiver.
The pilot is disconnected from the ICS. The COM 1 transceiver and NAV 1 receiver and DIRECT AUDIO are not
available to the other users. All other functions of the JA95 will operate. The LEDs, legends and annunciators will
retain normal functionality.
