Section 1 Description

1.1 Introduction

This manual contains general information on the AA30-0xx Expansion Switches. There
are many different variants of the AA30-0xx available; in this manual 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. All derivative products will be covered by manual supplements, which
can be obtained from NAT as required.

Information in this section consists of purpose of equipment, features and specifications.

1.2 Purpose of Equipment

The AA30-013 is a single-position expansion switch, and the AA30-014 is a dual­position expansion switch. Both provide transmit capability.

1.3 Features

The AA30-013 is a compact Dzus mounted switch expansion unit that provides
expansion for one user and contains only one board. The AA30-014 is a compact Dzus
mounted switch expansion unit that provides independent expansion for two users,
using two identical circuit boards.

The transmit function allows each user to select one of three transceivers (or two
transceivers and intercom). Receive audio can be selected regardless of the transmit
selector switch position.
