INTRODUCTION
This manual describes how to use the MDX Conventional Mobile Radio.
The MDX is a synthesized, microprocessor-based, high performance simplex
mobile FM radio providing reliable two-way communications. Direct mobile
to mobile communication, when out of repeater range, is also provided.
In the Conventional mode, the user selects a channel and directly
communicates on that channel. In this mode, a system refers to a set of channels
and a channel is a transmit/receive radio frequency pair.
The exact operation of the radio will depend on the operating mode, the
radio’s programming, and the particular radio system. Most features described
in this manual may be enabled or disabled through programming. Consult the
system administrator for the particular features that are programmed into your
MDX radio.
