3.4.9 ISO/CALL Switch
The ISO/CALL button is a momentary push-button switch that can be used to enter
ISO (isolation) mode (crew only) or to call the crew when in ISO mode. For further
information on ISO mode, see section 3.4.
3.4.10 RX/ICS Volume Control
The master RX/ICS Volume control is a dual concentric knob. The upper (inner) knob
controls the ICS volume potentiometer and the lower (outer) knob controls the master
receive volume for the unit.
Rotating the ICS knob cw will increase the ICS volume and ccw will decrease the
volume.
The master RX pot affects all Transceiver and Receiver receive volumes. When rotated
fully ccw it reduces all receive volumes by 75% and increases them all proportionally as
it is rotated cw. When rotated fully cw the master volume is set to maximum.
3.4.11 CALL Indicator
The ACP has one dead-front CALL indicator that flashes to signify that another user is
calling when the system is in ISO mode.
The CALL Indicator will flash at 1 Hz for a Normal Call and at 3 Hz for a
High Priority call.
For further information on Normal and High Priority calls see section 3.5.3.
