associated transceiver can be adjusted by rotating the knob and the illumination of the
triangular arrow will be at maximum. In the off position the knob is retracted (pressed
in), the volume is selected to the minimum value (off) and the arrow illumination is
minimized or off.
Above each control knob is a Transmit Access indicator which will illuminate green
when the associated transceiver is selected (by the transmit selector) and the ACP
has access to that transceiver. If access to that specific transceiver has been
restricted through the AMU DevCS the indicator will remain dark.
3.4.2 Transmit Active Indicator
The ACP has an NVIS Green B 'dead-front' TX indicator that illuminates when the
unit is transmitting on any transceiver.
3.4.3 Receiver Radio Controls (ACP53 and ACP54 only)
The ACP has up to eight Receiver audio volume controls with interchangeable
illuminated labelling to allow selection of suitable legends.
The receiver volume control is an edge-lit rotary plastic knob that is used to control the
volume for a specific receiver. Rotating the knob cw will increase the volume and
ccw will decrease the volume. The master RX Volume control can be used to effect a
global adjustment to all Transceiver volumes (see section 3.4.10).
Each control has a push-on/push-off action to allow individual selection of the required
receivers. In the on position the control knob is extended, the volume for the associated
receiver can be adjusted by rotating the knob and the illumination of the triangular
'arrow' will be at maximum. In the off position the knob is retracted, the volume is
selected to the minimum value (off) and the arrow illumination is minimized or off.
