INTRODUCTION
This manual describes how to use the DPE-100
Portable Radio. The DPE-100 is a synthesized, micro-
processor-based, high performance duplex portable FM
radio providing reliable two-way communications in En-
hanced Digital Access Communications System
(EDACS) trunking environments.
Duplex is provided in EDACS systems while operat-
ing in the Telephone Interconnect Mode. In an EDACS
trunked environment the user selects a communications
system.In this mode, channel selection is transparent to
the user and is controlled via digital communication with
the system controller. This provides advanced program-
mable features and fast access to communication chan-
nels.

the particular radio system. Most features described in
this manual may be enabled or disabled through pro-
gramming. Consult the system administrator for the re-
quired features to be programmed into the radio.

ALERTTONES
The DPE-100 radio generates a set of unique alert
tones to indicate operating status.The following section
identifies and describes the alert tones used in the
Duplex radio for EDACS applications.
CALL ORIGINATE ALERT
Ifprogrammed,ashort toneissoundedwheneverthe
S key is pressed and the radio has acquired a
channel.This tone indicates the user may begin com-
munications.
CALL QUEUED
If one short, high pitched tone sounds after the trans-
mitter is keyed, this indicates that the system has
placed the request in a queue. This tone sounds at
both the transmitting unit and the receiving unit(s),
indicating to the user on the receiving end that they
will receive a call shortly. If the S key is pressed
while in queue, the radio autokeys (automatically
keys) sends when a channel becomes available (see
AUTOKEY).
AUTOKEY
When the S key is pressed to place a call on the
system, but is released before the channel is as-
signed (e.g. a queued call), the radio automatically
keys onthe channel whenitgets theassignment.The
radiogeneratesalongbeepandholdsthetransmitter
keyed for two seconds.Pressing the S key keeps
the channel and sends the message before this two
second time-out has expired.
