SECTION 1. INTRODUCTION
The DX340ES is a digital wireless communication system that enables hands-free two-way secure communication on
two independent channels, or both channels at the same time. It can be operated with AC or battery power. Multiple base
stations can be interconnected for expanded capabilities.
In addition to the standard communication among base station and beltpac operators, the system can be congured to
operate with almost any radio or digital matrix (4-Wire) communication system.
This manual provides detailed setup and operating instructions for your DX340ES system.
The following examples are of typical DX340ES applications.
