INTRODUCTION
This manual describes how to use the EDACS PRISM
HP/LPE-200 Radio. The PRISM HP/LPE-200 is a synthesized, microprocessor-based, high performance portable FM radio providing reliable two-way communications in both the Enhanced Digital Acc ess Communications System (EDACS) trunking environment and conventional communication systems.
In the EDACS or trunked system mode, the user
selects a communications system and group. In this
mode, channel selection is transparent to the user and
is controlled via digital communication with the system
controller. This provides advanced programmable features and fast access to communication channels.
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. A channel is a
transmit/receive radio frequency pair.
Advanced hardware and software technology enables this radio to support all advanced EDACS radio
features and multiple communications modes including
digital. Depending on the customer’s needs, the Prism
HP is available in both System and Scan Modes.
Some key features include:
•
Field upgradable to TDMA
•
Data capable
•
Automatic power control for extended battery life
7
•
Up to 800 system/group combinations and up to 300
conventional channels
The LPE-200 radio operates similar to the PRISM HP
except it is not upgradable to TDMA operation. Translucent keys are used on the LPE-200. The LPE-200 is also
available in both System and Scan Models.
USER INTERFACE
The PRISM HP/LPE-200 operating controls are located on the radio’ s front, top and left panels. A 6-b utton
(scan model) or 15-button (system model) keypad, Liquid
Cry stal Display (LCD), microphone and speaker are on
the front panel. The top panel houses a rotary SYSTEM/GROUP/ CHANNEL knob , POWER O N-OFF/VOLUME control knob and an EMERGENCY button. An
OPTION button, CLEAR/MONITOR button and the
Push-To-Talk (PTT) button are all located on the left side
panel. The Univ ersal De vice Connector (UDC) is located
on the right panel and is used while programming the
radio and for accessory connection. A battery release
button is located on the back adjacent to the PPT button.
The display has three, twelve character alphanumeric
lines used to show the operational mode of the radio. A
back light illuminates the display and the keypad for
nighttime use. An LED is located on the front top edge of
the radio. Red indicates transmit.

DSP ERR
DSP ERR
ERR=XXXX
(Power Up only)
UNIVERSAL DEVICE CONNECTOR (UDC)
The Universal Device Connector (UDC) provides
connections for external accessories such as a headset
or a speaker-microphone. When the radio is locked in a
vehicular charger/repeater the UDC provides the audio
and control connections between the radio and the vehicular charger/repeater. The UDC is also used to program and service the radio.
25
ALERT T ONES
The PRISM HP/LPE-200 radio also provides audible
aler t tones or "beeps" to indicate the various operating
conditions. These alert tones can be enabled or disabled
through programming.
Call Originate
A short mid-pitched alert tone sounds after keying the
radio (Push-To-Talk button is pressed). This indicates the
radio has been assigned a working channel or that the
radio is transmitting on a conv entional channel and voice
communication may begin immediately.
Call Queued (Trunked Mode Only)
A high-pitched tone after pressing the PTT button
indicates the sys tem has placed the call request in the
queue. T he receiving unit(s) also hear the tones, indicating they will receive a call shortly. If the the PTT button is
released, the radio will autokey whenever a channel
becomes available (see Autokey).
Autokey (Trunked Mode Only)
After being placed in queue (see called queued), the
site calls the radio when a channel becomes available.
At this point, the radio automatically keys the tr ansmitter
(autokey) for a short period to hold the channel. The radio
sounds a mid-pitched tone when it is clear to talk; immediately press the PTT button to keep the assigned channel.
26
System Busy (Trunked Mode Only)
Three low-pitched beeps will be heard if: 1) the radio
is keyed when the system is busy, 2) if no channels are
av ailable f or sending the message, 3) if the call queue is
full, 4) or if an individual call is being attempted to a radio
that is transmitting. Releasing the PTT button and re-keying initiates a new channel request.
Call Denied (Trunked Mode Only)
If the radio is keyed and a low pitched tone is heard
then the radio is not authorized on the system that has
been selected.
Carrier Contr ol Timer
If the programmed time for continuous transmission
is exceeded, five short high-pitched warning tones followed by a long low-pitched tone will be heard. The
transmitter will shut down shortly after hearing the alert,
interrupting communications. Release and re-key the
PTT button to maintain communications. This will reset
the carrier control timer and turn the transmitter back on.
Low Battery W arn ing
A low-pitched tone is heard and comes on indicating that the battery voltage is low. Double tones are
then heard until the PTT or CLEAR button is pressed.
27
Low Battery Alert (Transmit Lockout)
If the radio is ke yed and a doub le tone is heard as well
as is displayed, the battery is discharged
LOW BATT
beyond the point where the radio will transmit. The radio
will still be able to receive calls until the battery is discharged beyond the point of operation, after which the
battery will need to be recharged to resume normal
operation.
Key Press Alert
A shor t tone or "beep" sounds to indicate a key has
been pressed. A short low-pitched tone indicates the key
is not active in the current mode.
OPERATION
TURNING ON THE RADIO
1. Turn on the radio by rotating the POWER ON-
OFF/VOLUME knob clockwise. A shor t aler t signal
(if enabled through programming) indicates the radio
is ready to use.
2. The display shows the last selected system and
group or a default system and group (depending on
programming).
3. Adjust the POWER ON-OFF/VOLUME knob to the
desired volume level.
4. Select the desired system and group (see system

5. The radio is now ready to transmit and receive calls .
NOTE
In the EDACS trunked environment,
CC SCAN
will be displayed if communication
with the system’s control channel cannot be
established. This may occur if, for example, the
radio is out of range of the trunking site. It ma y be
necessar y to move to another location or s elect
another trunking system to re-establish the
control channel link for trunked mode operations .
CC SCAN
is displayed on group line until a
