Multi-function (Transmit/ICS) Selection Switch    

 

The unit will transmit on the selected transceiver when the switch is held 
in the ‘up’ position, and when held in the ‘down’ position, it will transmit on 
the intercom. 

See section

and 

3.7

 

below for Multi-function switch functionality

 

This is a rotary knob that adjusts the 
phones volume of the receive audio 
from minimum (CCW) to maximum 
(CW). Individual radio volume 
controls should be set to a nominal 
level, and then adjusted for changing 
flight conditions using this control. 

 

This is a red two-position locking toggle 
switch. When set to the ‘up’ position, the 
unit is Emergency mode, and when set to 
the ‘down’ position, the unit is in Normal 
mode. The legends are interchangeable to 
allow customization. (Default – EMER, 
NORM.) 

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. The legends are 
interchangeable to allow customization.
