Transmit Access Indicator
The ACP53 has eight Transceiver Receive audio volume controls with interchangeable
illuminated legends to allow selection of suitable identification.
Each control is an illuminated rotary knob that is used to control the volume for a specific
transceiver. Rotating the knob clockwise (cw) increases the volume, and counterclockwise
(ccw) decreases the volume. The master RX Volume control can be used to effect a global
adjustment to all Receiver and Transceiver volume levels (see 3.4.10).

3.4.3 Transceiver Radio Controls
Each control has a push-on/push-off action to allow individual selection of the required transceivers. In
the on position, the control knob is extended, the volume for the associated transceiver can be adjusted
by rotating the knob, and if backlighting is on, 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 if backlighting is on, the arrow illumination is minimized or off.
Above each control knob is a Transmit Access indicator, which illuminates green when the associated
transceiver is selected (by the transmit selector) and the ACP53 has access to that transceiver. If access
to that specific transceiver has been restricted at installation, the indicator remains dark.

3.4.5 Receiver Radio Controls
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 if backlighting is on, 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 if
backlighting is on, the arrow illumination is minimized or off.
The ACP53 has eight Receiver audio volume controls with interchangeable illuminated
labelling to allow selection of suitable legends.
The receiver volume control is an illuminated rotary knob that is used to control the volume
for a specific receiver. Rotating the knob clockwise (cw) increases the volume, and
counterclockwise (ccw) decreases the volume. The master RX Volume control can be used
to effect a global adjustment to all Receiver and Transceiver volume levels (see 3.4.10).
The ACP53 has a dead-front TX indicator that illuminates when the unit is transmitting on
any transceiver.
