Ericsson EDACS M-RK I, Operator'S Manual, Page: 13 / 76

INTRODUCTION
This manual describes the operation of the EDACS
M-RK l Portable Radio. The M-RK l is a synthesized,
microprocessor-based, high-performance portable FM
radio providing reliable two-way communications for En-
hanced Digital Access Communications System
(EDACS) trunking environments and conventional com-
munication systems.
In the EDACS or trunked system mode the user
selects a communications system and group. In this
mode, radio channel selection is transparent to the user;
it is controlled by digital communication with the EDACS
site equipment. This provides advanced programmable
features and fast access to communication channels.
In conventional mode, the user selects a radio chan-
nel and directly communicates on that channel. In this
mode, a system refers to a set of channels. A channel is
a transmit/receive radio frequency pair.
The radio’s exact operation will depend on its current
operating mode, its programming, and the particular
radio system. Many features described in this manual
can be enabled or disabled through programming. Con-
sult the system administrator for the particular features
that are programmed into the M-RK l.
