OPERATION
The
LPE-200
series of portable radios is designed for
EDACS
and conventional mode operation. When the unit is
used in a trunked
EDACS
, the digital control channel
is
automatically monitored. When the user initiates a call, the
unit sends a digital request through a control channel to the
site controller. The site controller then assigns the calling
radio and all members of the talk group to an available
working channel. All operations in
EDACS
configurations
are supported from a single-site system to wide-area
trunking networks.
For more detailed operating instructions refer to
Operator’s Manual

emergency button mounted on the top of the radio, with
side-mounted push-to-talk, monitor/clear and option buttons.
The front-mounted keypad has 6 buttons on the Scan and 15
buttons on the System (refer to Figure 1).
