SM73 Rev. 4.00 AA30-0xx Expansion Switches Manual
Section 3 Operation
3.1 Introduction
Information in this section consists of the functional and operational procedures for the
AA30-0xx Expansion Panels.
The AA30-013 is described as an example of a single user unit, and the AA30-014 as
an example of a dual user unit.
3.2 General
The AA30-0xx Series are Dzus-mounted expansion panels designed to expand a single
transceiver selection from an audio control panel to allow three transceiver selections.
These units are generally part of a larger system with other audio controllers or
equipment; the whole system must be considered, not just the AA30-0xx accessory unit.
3.3 Controls and Indicators
The controls on both the dual and single user versions of the AA30 work in a similar
manner; for simplicity, only one set of controls will be described.
Transmit Selectors
Receive Audio Switches
3.3.1 Transmit Selector
The transmit selector is a rotary plastic switch used to select the transceiver output for
transmission.
3.3.2 Receive Audio Switches
The three receive audio selection switches are two-position on-off switches. They select
the required receive audio when in the 'up' (on) position.
