INTRODUCTION

This manual describes how to use the EDACS
PRISM HP Radio. The PRISM HP is a synthesized,
microprocessor-based, high performance portable FM
radio providing reliable two-way commu nications in both
the Enhanced Digital Access 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 sel ection is transparent to the user and
is controlled via digital communication with the system
controller. This provides advanced programmable fea­tures and fast access to communicat ion channels.

In the conventional mode, the user se lects 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.

7

USER INTERFACE

The PRISM HP operating contro ls are located on the
radio’s front, top and left panels. A 6-butt on (scan m odel)
or 15-button (syst em model) keypad, Liquid Crystal Dis­play (LCD), microphone and speaker are on the front
panel. The top panel houses a rotar y SYSTEM/GROUP/
CHANNEL knob, POWER ON-OFF/VOLUME control
knob and an EMERGENC Y button. An OPTI ON button,
CLEAR/MONITOR button and the Push-To-Talk (PTT)
button are all located on the left side panel. The Universal
Device Connector (UDC) is located on the right panel
and is used while programming the r ad io and for acces ­sory connection. A battery rel ease 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 us e. An LED is located on the front top edge of
the radio. Red indicates transmit.

Error Messages

If either of the following error messages is displayed,
the radio was either programmed incorrectly or needs
servicing:

DSP ERR

DSP ERR

ERR=XXXX

(Power Up only)

UNIVERSAL DEVICE CONNECTOR (UDC)

The Universal Device Connector (UDC) provides
connections for ex ternal acc essories s uch as a headset
or a speaker-micr ophone. 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.

ALER T TONES

The PRISM HP radio also provides audible alert
tones or "beeps" to indicate the various operating condi­tions. These alert tones can be enabled or disabled
through progr amming.

25

Call Originate

A short mid-pit ched alert tone sounds af ter keying the
radio (Push-To-T alk button is pressed). This indicates the
radio has been assigned a working channel or that the
radio is transmitting on a conventional channel and voice
communication may begin immediately.

Call Queu ed (Trunked Mode Onl y)

A high-pitched tone after pressing the PTT button
indicates the system has placed the call request in the
queue. The receiving unit(s) also hear the tones, indicat­ing they will receive a call shortly. I f 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 c a lled queued), the
site calls the radio when a channel becomes available.
At this point, the r adio automatically keys the transm itter
(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 ass igned chan­nel.

System Busy (T runked Mo de Only)

Three low-pitched beeps will be heard if: 1) the radio
is keyed when the system is busy, 2) if no channels are
available for sending the message, 3) if the call queue is
full, 4) or if an individual call is being attem pted to a radio

26

that is transmitting. Releasing the PTT button and re-key­ing initiates a new channel request.

Call Deni ed (T run ked Mode Onl y)

If the radio is keyed and a low pitched tone is heard
then the radio is not authorized on the system that has
been selec ted.

Carrier Control 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
transmit ter wi ll 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 transmit ter back on.

Low Battery Warning

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.

Low Battery Alert (T ransmi t Lo ckou t)

If the radio is keyed and a double tone is heard as
well as is displayed, the battery is dis-

LOW BATT

charged beyond the point where the radio will transmit.
The radio will still be able to receive calls until the bat tery
is discharged beyond the point of operation, after which

27

the battery will need to be recharged to resume normal
operation.

Key Press Alert

A short 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 short alert 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

and group selection section). The display indicates
the current syst em and group names.

5. The radio is now ready t o transmit and r eceive calls.

28

NOT E

In the EDACS trunked environment,

CC SCAN

will be displayed if communication
with the system’s control channel cannot be
established. Thi s may occur if, for example, the
radio is out of range of the trunki ng site. It may
be necessary to move to another location or
select another trunking system to re-establish the
control channel link for t runked mode operations.

CC SCAN

is displayed on group line until a
control channel is accessed.

TRUNKED MODE OPERATION

Digital trunking provides fast communication access
at all times, even during busy hours. In this mode the
operator selects a communications system and group
and the audio communication or working channel (WC)
is allocated through digital signalling with the site.

Receiving A Group Call

1. Turn on the radio by rotating the POWER ON-

OFF/VOLUME knob clockwise. A short alert signal
(if enabled through programming) indicates the radio
is ready to use.

2. GROUP CALL - When the radio receives a group

call, it unmutes on the assigned working channel and

comes on. Line one shows GR followed by the
logical ID number (if received) of the unit sending the
message, or the associated name if the ID number
is found in the individual call list.

34

3. The Prism HP stores the initiating radio ID’s of the
last 10 group c alls received on the selected c hannel.
To access this list press the

#

key twice.

The initiating radio ID of the last group call received
is shown on line one of the display. Use the

>

view the radio ID’s of other radios that initiated group
calls. Pressing the

M

key will display the time

elapsed since that call was received.

Pressing PTT will initiate an individual call to the
displayed radio ID. T urning the radio off will clear this
list.

Note: The list described above also functions to
store previous individual calls received. See “Indi-
vidu al Call s ” section for details.

35

Sending A Group Call

1. T urn on the radio and set the POWER ON-OFF/VOL­UME knob to the desired volume level. Select the
desired system and group.

2. Press and hold the PTT button. The radio will display

the system and group names and perform the
necessary signalling required to obtain a communi­cation channel.

3.
When the working channel is assigned, and

are displayed and a short mid-pitch tone sounds
(if programmed) i ndicating communication can be­gin.

NOTE

If two or more tones, or a high pitched tone is heard,
the system may be busy and the call request has
been placed in queue or t he request has been denied
for some reason. Refer to the ALERT TONES section
for more details.

4. Hold the radio approximately three inches from the
mouth and speak in a normal voice into the micro­phone (located upper-left of speaker grille).

5. Release the PTT button when the transmission is
comp lete and listen for a reply.

36

Conventional Failsoft

In the unli kely event of a failure o f the EDACS Sys­tem, communications may take place in conventional
failsoft mode. The radio will be automatically directed to
a commun ications channel set up for this purpose. Dur­ing this mode of operation, " CO NV FS" will be displayed
in the alphanumeric display . An increase in activity on the
channel during conventional failsoft operation may be
noticed, so be caref ul not to transm it unti l the channel is
clear .

Operation during conventional failsoft will be the
same as operation on a conventional system, except that
it will not be possible to select a communications chan­nel, or use emergency and special call. When trunking
is restored, the radio will automatically be returned to
normal operation.

NOTE

Emergency and Special Call are not operational dur­ing conventional failsoft. Also, the GROUP will not
operate.

Emergency Operati o n

The radio’s ability to declare an emergency, clear an
emergency , remain locked on an emergency system and
group, and the em ergency audio and d isplay freeze can
each be enabled or disabled through programming.
When an emergency is declared scanning will stop and
restart s only after the emergency has been cleared.

37

Receiving An Emergen cy Call

When receiving an emergency call on the selected

group and system , an alert beep is heard and comes
on. The message flashes in the display on

*RXEMER*

line two until the emergency condition is cleared.

Declaring An Emergency Call

To send an emergency call to selected system and
group (or on an optionally preprogrammed group), pro­ceed as follows:

1. Press and hold the red EMERG ENCY but ton that is

on top of the r adio in front of the antenna f or approxi­mately one second (this time is programmable and
therefore could be longer or shorter; check with the
system administrator). The radio will transmit an
emergency call request with the radio ID until an
emergency channel assignment is received.

2. When the working channel assignment is received,

the radio sounds a single beep indicating the radio
has auto keyed (see Auto Key) and is ready for
voice transmission.

*TXEMER*

flashes on line two in the display until

the emergency is cleared.

3. Press PTT and speak into the microphone in a

normal voice. and momentarily turns on.

4. Release PTT when the transmission is complete.

SCANNING TRUNKED SYSTEM S

Wide Area System Scan ning

The PRISM HP radio may be programmed for wide
area system scan operation for roaming across mobile
systems. Upon the loss of the currently selected sys­tem’s control channel, radios may be programmed to

44

automatically scan the control channels of other sys­tems. If a new control channel is found, the radio will
switch to the new system and sound an alert tone.

Priority System Scan

The radio may also be programmed for priority sys­tem scan. A pr iority system may be assigned among t he
systems programmed into the radio. Radios pro­grammed in this manner will check for the priority trunked
system’s control channel at a programmable rate ranging
from 1 to 16 minutes. This priority scan timer is reset each
time the PTT button is pressed or when a call is received.
If the priority system control channel is found, the radio
will automatically sw itch to the priority system .

ProSo und



The radio may be pr ogrammed f or ProSound sy stem
scan operation for multi-site applications. ProSound
scanning is an enhanced replacement for wide area
system scanning. This algorithm insures that the radio
continually receives high quality audio. When the se­lected system degrades to a pre-programmed level, the
radio changes to the new system and sounds a tone.
Should the control channel be lost completely, the radio
will scan the adjacent systems until a suitable one is
found.

DTMF Overdial / C onventional M ode Telephone
Interconnect

Once the radio has established a connection to the
public telephone system, it may be necessary to "over­dial" more digits to access banking services, answering
machines, credit card calls or other types of systems that
require DTMF (Dual-Tone Multi-Frequency) access dig­its.

Overdial operation can also be used to initiate a
telephone interconnect call via DTMF signalling if a dial
tone has already been accessed on the system. This is
the method that is used for making a telephone interc on­nect call while operating in the conventional mode but
will also function in trunked mode if a dial tone is directly
accessible.

T elephone numbers and other number sequences for
overdialing can be stored in the phone list when program­ming the radio. These numbers are accessed by press­ing

M

, then following the selection mode rules.

54

The following steps are required to dial these numbers :

the site at a future time. Status messages can also be
programmed for single key operation so that a single
press of a key assigned to a status message automat­ically transmits that message. If the s ite does not receive
the status properly, the radio will sound a low pitched
tone.

The status selection can also be canceled by press-

ing the CLEAR button prior to the time-out period.

To view the currently selected stat us after it has been

M

key again and then the
CLEAR button prior to the time-out period. If the status
was not sent succes sfully to the site, t he text assoc iated
with the status w ill flash in the display.

MESSAG E OPE RATION

Message operation is perfor med in the same manner

as status operation in previous paragraph.

DYNAMIC REGROUP OPERATIO N

Dynamic group operation permits multiple talk groups
(up to eight) to be added to a radio via the system
manager. The radio must be pre-programmed to re­spond to regrouping. Dynamic regrouping will not be
activated in a radio until an activation message is sent
by the system manager. Each radio that receives and
acknowledges the regrouping instructions is success­fully regrouped.

59

Pressing and holding the CLEAR/MONITOR button
for 2.5 seconds toggles the user into and out of the
dynamic regroup groupset. A double beep will sound for
entry or exit. The display will indicate "REGRP_0x"
where "x" is a digi t of 1 t o 8 indicating the group when
dynamic regroup has been enabled by the user. If the
radio is in dynamic regroup and the user select s a group
that has not been regrouped, the display will show "NO
ENTRY". The radio will be prevented from transmitting
and receiving calls i n this condition except for scanned
groups.

Emergency Operati o n

If the pre-programmed groupset on the currently se­lected system contains an EMER/HOME group and the
radio is in dynamic regroup, the radio will declare the
emergency on the currently selected dynamic group
group.

MACRO KEY OPE R ATION

Macro key operation permits the user to accomplish
a series of key s trok es with a single "m acro" k ey stroke.
Up to ten (10) macro keys can be defined, each capable
of executing up to twenty (20) key strok es, t o any push ­button input (i.e., keypad keys, OPTION button, etc.).
Each macro key can be pre-programmed to activate
when pressed or when released.

A macro key may also be pre-programmed to change
the key stroke sequence the next time the macro key is
activated.

60

For detail operation and assignment of macro keys,
contact your communi cations supervisor or administra­tor.

EDACS CONVENT IONAL P1 SCAN

This feature perm its the radio user to scan a pre-pro­grammed convent ional system and c hannel as a Priority
1 (P1) channel while the radio is selected for EDACS
trunked system. If activity is detected on the conventional
P1 channel, the radio will unmute and remain on this
conventional channel for the programmable hang time.

The radio must be pre-programmed to designate a
key for P1 scan on/off operation.

AEGIS OPERATION

VOICE MODES

Aegis programmed systems have three (3) different
voice modes: clear (analog), digital and private (en­crypted). The voice modes are programmed on a per­group basis within each trunked system and on a per­channel basis within each conventional system.

Mode 1: Clear Modes

The Aegis clear mode is a voice mode i n which the
radio transmits and receives only clear (analog) voice
signals. These analog signals are non-digitized and non­encrypted. Clear mode transmissions can be easily
monitored by unauthorized persons. Groups or channels
programmed for clear operation cannot transmit or re­ceive Aegis digital or private messages.

Mode 2: Aegis Digital Mo d e

The Aegis digital mode allows the radio to transmit
and receive digitized voice signals. Aegis digital signals
provide improved weak signal performance and cannot
be easily monitored with a standard receiver. Groups and
channels programmed for Aegis digital operation trans­mit only digital signals. Private (encrypted) calls cannot
be received or transmit ted when the r adio is in the Aegis
digital mode because the radio does not know the cryp­tographic key used. Message trunked group calls and
individual calls are answered back in the mode which
they are were received assuming t he call or hang time is
still active. Individual phone, all, and emergency calls are

71

transmitted clear if the digital mode is disabled or inop­erative.

1. If receiving an analog message trunked call, the
radio responds in the analog mode during the hang
time on the working channel.

2. If receiving an analog I-Call, the radio responds in
the analog mode during the hang time.

3.

When using the feature to respond to an

*WHC*

I-Call (after the hang time has expired), the call is
transmitted in t he mode defined by the sy stem mode
as programmed for the curr ent system if the ID being
called is not in the I-Call list. If the ID is in the I-Call
list, then the call is transmitted as defined by the
I-Ca ll mode programmed in the list for that ID.

DTMF

The overdial DTMF tones are not available whil e in

the Aeg is Digital Mode.

Mode 3: Aeg is Pri vate Mod es

The Aegis private modes allow the radio to transmit
encrypted messages and receive clear or private trans­missions. The radio transmits private if the group/chan­nel is programmed for private operation and forced op­eration is pre-programmed. If autoselect operation is
pre-programmed and the radio is in the private mode, the
radio transmits in the mode of the received call if the hang
time is active. If no hang time is active, the radio transmits
private.

72

Cryptographic k eys are transfer red to the radio using
a cryptographic Keyloader. Up to seven (7) different
cryptographic keys, numbered 1-7, can be transferred
from a Keyl oader and stored in the radio. An individual
key is automatically selected on a per-group/channel
basis according to the radio programming. Groups and
channels within the Aegis system can be programmed
for keys 1-7 (DES and VGE). Up to 8 banks of 7 keys
can be stored for Aegis (DES and VGE) systems. The
bank is specified per system.

DES rad ios require a DES Keyloader (Opt ion V4025
with software version 3.N or later). VGE radios require
VGE Keyloader (Option V4028 with software version 2.N
or later).

When operating on a group or channel programmed
for private mode, al l transmissions are pr ivate t ransm is­sions and the radio receives clear and private signals.

The status icon display turns on when the private
mode is enabled. If the selected group or channel is
programmed for aut oselect c apability, the mode may be
toggled between private and clear with the

M

key , then
following the selection mode rules. Radios programm ed
for forced pr iv ate operation do not allow a change of the
transmit mode.

Transferrin g Keys Into the Radio

The following procedure outlines basic key t ransfer-

ring steps.

1. Turn the radio off.

73

2. Plug the modular connector of the Keyloader cable
into the Keyloader modular jack.

3. Connect the Keyloader cable to the UDC on the
radio.

4. Press the PWR butt on on the Keyloader and wait fo r
the Keyloader to display “MASTER MODE ”.

5. Press the TRN button on the Keyloader. If neces­sary , select a different cr yptographic key to be trans­ferred into the radio.

6. Turn the radio on. The top line on the radio display
will read “KEY LOAD” and the second line will read
“BANK = N” where N=keybank number. Press the

<

or

>

button to select the keybank. A beep

will indicate that the keyloader is connected.

7. Press the EXE button on the Keyloader to transfer
the key. The Keyloader will display “GOOD 1.x
TRANSFER” where “x” is the select ed cryptographic
key number .

8. Disconnect the cable from t he radio UDC. The radio
will change to the selected group or channel as
indicated in the display .

Displaying The Currently Used Cryptographic Key
Number

To display the cryptographic key currently in use for

either the system encry ption key (for special call such as

74

individual, phone, all, agency or fleet) or the group/c han­nel key (for group or conventional calls), perform the
following procedure:

Key Zero

All cryptographic keys can be zeroed (erased from
radio memory) by pressing the MONITOR/CLEAR but­ton and while s til l pressi ng thi s button, press and hold
the OPTION button. Press bot h buttons for 2 seconds. A
series of beeps will begins at the start of the 2 second
period and then switch t o a solid tone after the keys have
been zeroed. The display will indicate “KEY ZERO.”

If the cryptographic key(s) are zeroed, one or more
keys must be transferred from the Keyloader into the
radio before private communicat ions may continue.

Private Operation
Receiving An En crypted Call

When receiving, the radio automatically s witches b e­tween clear or private operation. If the transmission
being received is an encrypted transmission, it will be

decrypted, the icon will turn on, the receiver will
unsquelch and the message will be heard in the speaker.
For this to occur, the select ed group or channel m ust be
programmed for pri vate operation and the correct cryp­tographic key must be loaded into the radio.

Transmitting An Encrypted Cal l

1. Select the desired group or channel.

2.

Place the radio in private mode by pressing the
key, then follow the selection mode rules. On a
System radio, the

76

4

M

key can be used to toggle

the private mode on/off . When private mode is en­abled, the icon will be on.
If the last state of the radio was pri vate mode, the

private mode will be enabled on power up. Also the
private mode will be enabled if forced operation has
been programmed in the radio.

If a group or channel is not programmed for private
mode operation, “PVT DIS” will be displayed if at­tempt is made to enable private trans mit mode. It is
not possible to operate on this group/channel in
private mode.

If the rad io does not have the correct enc ryption key
loaded, “NO KEY#” will be displayed and the call will
not be transmitted.

3. Continue with standard transmission procedures. A
private mode access tone will be heard when the
PTT button is pressed.

Scanned G rou p Calls

Receiving a scanned group call is the same as receiv­ing a selected group call. During the scan hang time, if
the radio was programmed for autoselect , it will transmit
back in the same mode it received the call. For example,
if a clear group is entered in the scan list, it will only
receive clear calls. I f the same group was availabl e in
private and entered in the scan list, it can receive clear
and private calls, provided autoselect was programmed
in the radio. The user can select transmitting on the

77

scanned or selected group. If a group is entered in the
scan list more than once and in different modes (clear,
digital, private), only the first occurrence of the group will
be used.

supported in the conventional mode.

The radios can be connected to Mobile Data Termi­nals (MDT ) or to a host com puter. Any RS -232 c ompat ­ible device that supports the Radio Data Interf ace (RDI )
protocol (Version 1.91 or greater) may be connected to
the radio. Support for MDT’s or host computers is a
programmable option per radio. Additionally , radios pro­grammed for host computers may also be programmed
for data only operation (no voice calls transmitted or
received).

DISPLAYS

The following will be displayed in the display during
the various states of data mode of operation.

TX DAT A

Displayed on top line of display when the
rad io is transmitting a data call.

EXITING DATA CALLS

Under normal conditions, the radio enters the scan
lockout mode and returns to the control channel after
completion of a data call (transmit or receive). If, during
a data call,one of the following conditions occurs, the

80

data call is immediately terminated and the radio per­forms the desired function:

••

PTT activated.

••

Emergency declared by pressing the pre-pro­grammed emer gency butt on.

••

A group or system change.

SCAN LOCKOUT MODE

Following the trans mission or reception of a data call,
if scan is enabled, scanning will stop temporarily [two
independent pre-programmed times (after receive data
call and after transmit data call)]. During this time the
scan indicator will flash to indicate that scan i s enabled
but temporarily suspended. This mode is normally exited
when the pre-programmed time expires; however, the
following actions will terminate the scan lockout mode
before the timeout is completed.

••

The CLEAR button is pressed.

••

The PTT is pressed.

••

A group or system change.

••

DATA L OCKOUT MODE

During the voice call scan hang time (pre-pro-

grammed) the radio will not receive data calls.

CONVENTIONAL MODE OPERATION

The radio functions in the conventional mode when
using conventional communications channels (non­trunked). Each channel consists of a preset frequency
pair for transmit and receive during repeater operati on,
or a single frequency for both transmit and receive during
talk-around (no repeater) operation. To use this mode,
the operator selects a conventional system which in­cludes one or more conventional channels. Each con­ventional channel may have one or m ore f eatures, s uch
as Channel Guard, programmed when the channel is
selected.

The CLEAR/MONITOR button unmutes the receiver
so activity on the selected channel can be monitored.
When pressed and held for approximately 3 seconds this
button toggles c onventional c hannel decoding (Channel
Guard, Digital Channel Guard ) on and off if programmed
for the selected channel.

82

Receiving A Call

1. Turn on the radio by rotating the POWER ON­OFF/VOLUME knob clockwise (out of detent). A
short alert signal (if enabled through programming)
indicates the radio is ready to use.

2. Adjust the POWER ON-OFF/VOLUME knob to the
desired volume level.

3. Select the desired conventional system and chan­nel. The display indicates the current conventional
system and channel names.

4. The radio is now ready to receive calls.

5. When the radio receives a call (and the correct
encoding is decoded, if programmed and enabled),

it unmutes on the channel and comes on.

Sendin g A Call

1. T urn on the radio and set the POWER ON-OFF/VOL­UME knob to the desired volume level. Select the

two way radio equipment, the user must be thoroughly
familiar with the rules that apply to the intended type of
radio operation. Following these rules will help to elimi­nate confusion, ass ure the m ost ef ficient use of exis ting
radio channels, and result in a smoothly functioning radio
network.

When using the radio, remember these rules:

1. It is a violation of FCC r u les to inter rupt any d istres s
or emergency message. In conventional mode the
radio operates in much the same way as a telephone
"party line" therefore always listen to m ake sure that
the line is clear --that no one else is on the air--bef ore
sending any messages. If someone is sending an

87

emergency message--such as reporting a fire or
asking for help in an accident--KEEP O FF THE AIR!

2. Use of profane or obscene language is prohibited by
Federal Law.

3. It is against the law to send false call letters or a false
distress or emergency message.

4. The FCC requires that conversations be brief and
confined to business. To save time, us e coded mes­sages whenever possible.

5. Using the rad io to send personal m essages (except
in an emergency) is a violation of FCC rules. Only
those messages essential for the business operation
may be sent.

6. It is against the Federal law to repeat or otherwise
make known anything overheard on the radio. Con­versations between others sharing a communica­tions channel must be regarded as confidential.

7. The FCC also requires that the ca ller be identified at
certain specific times by means of call lett ers. Ref er
to the rules that apply to the particular type of opera­tion for the proper procedure.

8. No changes or adjustment shall be made to the
equipment except by an author ized or certif ied elec­tronic technician.

88

OPE R ATING TI PS

The following conditions tend to reduce the effective
range of two-way radios and should be avoided when ­ever possible.

••

Operating the radio in low areas of terrain or while
under power lines or bridges.

••

Operating the radio inside of a vehicle or in a metal
or steel framed building unless using an outside
antenna.

••

Obstructions such as mountains or buildings be­tween the sending and receiving parties.

In areas where transmission or reception is poor,
some improvements may be obtained by insuring that
the antenna is vertical. Moving a few yards in another
direction or moving to a higher elevation may also im­prove communicat ion.

BATTERY P ACKS

CHARGING THE BATTERY PACK

After receiving a new rechargeable battery pack, it
should be fully charged before placing it into service. This
also applies to rechargeable batteries that have been
stored for long periods. When the battery pack requires
charging, the radio will signal the operator with an alert

tone and the radio will display in its LCD.

89

Chargers are available with nominal charge times of
one hour. Combinations include single and multiposition,
rapid charge units. When charging a battery pack that is
attached to a rad io, always turn the radio off to ensure a
full charge. For specific instruc tions refer to the applica­ble charger Operating Manual. Charging in non-Ericsson
equipment may lead to battery damage and void the
battery warrant y.

Batteries which have been stored (charged or dis­charged) will generally not be capable of full capacity
until the batteries have been fully cycled two or three
times. Charging a battery in an Eri csson rapid charger
and discharging the battery pack with the radio unt il low
battery is indicated is considered one cycle.

Improvements in the manufacturing of present gen­eration NiCD rechargeable batteries minimize the prob­ability of Ericsson batteries developing mem ory. If mem­ory is suspected, then it can be easily canceled by
charging and discharging the problem battery two or
three times. The battery should be charged on an
Ericsson rapid charger and discharged on the radio until
the low battery is indicated.
