INTRODUCTION
The Ericsson GE PCS™ Standard/Scan/DTMF portable radios are
lightweight, full-featured radios that provide reliable two-way
communications. The PCS comes in 2-, 8-, and 16-channel versions.
The SCAN function exists on the 8- and 16-channel radios and allows
monitoring of all channels. Any channel may be scanned with or without
a priority level. One channel can be programmed for Priority 1 (P1) and
another for Priority 2 (P2), with any or all remaining channels
programmed as non-priority channels. It also allows HOME channel
selection or Emergency mode transmission.
The User (also known as Universal) Device Connector (UDC), located
on the side of the radio, provides connections for external audio
accessories. This connector also allows the radio system personnel to
connect programming equipment and program the per-channel and
overall radio features. Consult the radio system personnel to determine
the programmed features of your radio. Features that are programmable
on a per-channel basis include:
•Receive Frequency
•Transmit Frequency
•High/Low Transmit Power
•Channel Busy Lock-Out
•Squelch Tail Elimination (STE)
•Channel Guard Encode/Decode (Tone or Digital)
•Type 99 Tone Decode
4

•Automatic Number Identification (ANI)
•Telephone Interconnect (DTMF Dial)
Features that are programmable on an overall radio basis include:
•Carrier Control Timer (CCT)
•Display Backlighting
•Alert Tones
•HOME Channel or Emergency Channel (on SCAN
versions)
•Three (3) Auto-Dial Telephone Numbers (on SCAN
versions)

CONTROLS
ON/OFF SWITCH The ON/OFF switch is
located on the battery pack.
Sliding this switch up to the
"ON" position will supply
power to the radio from the
battery pack. An audible
"click" will be heard.
When the radio is turned on, it
will resume operation at the
last operating state (channel,
volume, etc.) and the power-
up alert tones will be
sounded. Three (3) beeps
indicate the radio is in the
normal (receive mode); four
(4) beeps indicate the radio is
scanning. The operating
status of the radio will be
displayed in the Liquid Crystal
Display (LCD) window.
PTT BUTTON
(Push-to-Talk) Pressing the PTT button on
the side of the radio will key
the radio transmitter.
If the radio is not scanning, it
will transmit on the selected
(displayed) channel. If the
radio is scanning when the
PTT button is pressed, the
radio may be programmed to

transmit on the selected
channel or on the current re-
ceive SCAN channel.
If the selected channel is pro-
grammed with Type 99 Tone
Decode enabled, pressing the
PTT button will disable Type
99 Tone Decode by switching
the radio from the Selective
Call mode to the Monitor
mode. The PTT button must
be released and then pressed
a second time to key the
radio.
MONITOR BUTTON The MONitor button has sev-
eral functions. Its operation
will vary depending upon pro-
gramming.
If the MONitor button is pro-
grammed for "squelch" op-
eration, pressing it un-
squelches the receiver for the
first three (3) seconds the
button is held. All transmis-
sion will be heard, even if
Channel Guard protected.
This allows channel monitor-
ing before transmitting. If the
button is held for more than
three (3) seconds, Channel
Guard decode will toggle ON
or OFF (if it is programmed
on the selected channel). Continued ...

MONITOR BUTTON
(cont'd) If the MONitor button is pro- grammed for "Channel
Guard" operation, pressing
and releasing it within one (1)
second will toggle Channel
Guard ON or OFF. Pressing
and holding for more than one
(1) second will unsquelch the
receiver after one (1) second
and allow channel monitoring
as long as the button is held;
Channel Guard status will not
be affected.
The MONitor button is also
used to reset the radio after a
Type 99 call is received.
Quickly press and release the
button to reset the radio to re-
ceive the next Type 99 call.
VOLUME CONTROLS The speaker volume level is
controlled by the two buttons
on the side of the radio.
Pressing the VOLUME UP
(∆∆) button will increase
volume and pressing the
VOLUME DOWN (∇∇)button
will decrease the volume.

VOLUME CONTROLS
(cont'd) relative volume level is indi- cated in the LCD window by
four (4) bars. There are eight
levels of volume. Two levels
of volume are represented by
each bar.
Changing the volume while
the radio is squelched will
cause the radio to beep, if
programmed, at the new
selected level. No beep is
sounded if the radio is un-
squelched.
CHANNEL
SELECTION Select the transmit/receive channel by pressing the
CHANNEL UP (∆∆) or the
CHANNEL DOWN (∇∇) but-
ton. The channel number will
be displayed in the LCD win-
dow. Press the CHANNEL
UP button to increase the
channel and press the
CHANNEL DOWN button to
decrease the channel.
Channel selection will wrap
around (Channel 1 follows
Channel 16 [or Channels 2 or
8] when increasing channels;
Channel 16 [or 2 or 8] follows
Channel 1 when decreasing
channels).

The three (3) buttons (top three on the DTMF keypad) are used to
control a variety of operations when used alone and to control SCAN
operations when used in conjunction with the "S" button on the 8- and
16-channel radios. Details are as follows:
NOTE
These three buttons are also used to place telephone calls
("1" - "3" digits) when the telephone interconnect feature is enabled.
In addition, the "∆∆" UP ARROW button (HOME or digit "1") selects
the HOME/EMERGENCY channel (on the SCAN versions).
∆∆

The ∆∆ or "H" button
allows the following (see
SCAN Controls for further
details):
1. Add channels to
Scan list when used in
conjunction with the "S"
button (for 8- and 16-
channel radios). SCAN
must be off when adding
channels.
2. Programming of a
HOME or EMERGENCY

SCAN CONTROLS
Holding the "S" button and then pressing ∆∆ or ∇∇ keys (buttons) enables
the following functions. (These functions apply only to the 8- and 16-
channel radios.)
∆∆ Holding the "S" button while
pressing the ∆∆ button will add the
selected channel to the Scan list.
Repeating this sequence will
toggle SCAN status between
non-priority SCAN, Priority 2
SCAN, and Priority 1 SCAN.
When a channels' SCAN status
is changed, the status indicators
in the LCD window will be
updated. If a new Priority 1 or
Priority 2 channel is selected, the
previous corresponding Priority
channel will become a non-
priority channel.
∇∇ Holding the "S" button while
pressing the ∇∇ button will delete
the selected channel from the
Scan list. The SCAN Priority
status indicator in the display
window will turn off.
SCAN must be off to add or delete channels from the Scan list. (See the
SCAN operating procedures for more information.)

DTMF KEYPAD Telephone Interconnect calls
can be placed using the 12-
button DTMF keypad option.
This keypad is enabled when a
DTMF-programmed channel is
selected and the PTT button is
pressed. See the telephone
interconnect operating pro-
cedures and Figure 2 for more
details.
HOME CHANNEL
SELECTION/
EMERGENCY MODE
The HOME/EMERGENCY but-
ton, located on the 12-button
DTMF keypad (digit "1" or H)
can be programmed as a
HOME channel button or as an
EMERGENCY button. See the
HOME/EMERGENCY button
operating procedures for more
details.
INDICATORS
The Liquid Crystal Display (LCD) indicates the channel number and
volume. In addition, seven (7) status indicators show SCAN status, Type
99 Tone Decode status, transmitter keyed, and a low battery condition.
(See Figure 3.)
LCD backlighting will turn on anytime a control button is pressed. It will
remain on for five (5) seconds after the button is released. Backlighting
may be programmed to remain off at all times.
(For 2-channel radios the ∆∆ or 'H' button is programmed to turn on
backlight for as long as the button is pressed, remaining illuminated for 5
13

seconds after the button has been released, providing the button is held
for at least one second.)
CHANNEL AND VOLUME INDICATORS
The selected channel number is
displayed in the LCD window. In 2-
channel radios, the "P1" pixel will be
illuminated when high TX power is
selected, otherwise the "P2" pixel will
be lit to indicate a low TX power
setting. If programmed, the ∇∇ button
will toggle the TX power setting. If
this feature is disabled through
programming, the "P1" and "P2"
pixels will not be displayed. Changing
the channel after setting the TX power
will cause the EEPROM setting to be
reloaded.
Current volume level is displayed by
the volume bars. The radio has eight
different volume levels which are
represented by four bars (2 levels per
bar).

STATUS INDICATORS
SCN This status indicator turns on when
the radio is scanning (8- or 16-
channel radios).
SWhen this indicator is on, the selected
channel is a non-Priority SCAN
channel (for 8- or 16-channel radios).
When this indicator is lit in a 2-
channel radio, it indicates a selected
channel is in Talk Around mode.
P1 When this indicator is illuminated, the
selected channel is a Priority 1 SCAN
channel. This applies to the 8- and
16-channel radios only. On 2-channel
radios, if this feature is enabled, this
indicator is lit when the high TX power
setting is selected.
P2 When this indicator is on, the selected
channel is a Priority 2 SCAN channel.
This applies to the 8- and 16-channel
radios only. On 2-channel radios, if
this feature is enabled, this indicator is
lit when the low TX power setting is
selected.

ALERT TONES
Alert tones or "beeps" are sounded when a button is pressed and when
the operating status of the radio changes. All alert tones may be
programmed off.
17

POWER-UP SELF-TEST
Each time the radio is turned on it will perform a power-up self-test. All
display segments will turn on, and after successful completion of the
test, the radio will change to the last operating state (channel, volume,
etc.) and sound three (3) or four (4) beeps. Three beeps sound if the
radio is operating in the normal (not SCAN) state. Four beeps will sound
if the radio is scanning. The status will be indicated in the LCD. If the
radio fails the self-test, no beeps will be sounded.
CARRIER CONTROL TIMER
This feature, programmable on a per-channel basis, prevents
unnecessary channel traffic and radio damage if the transmit timer limit
is exceeded. If the programmed timer times-out during a transmission,
the radio will beep and stop transmitting. The beeping tone will continue
until the operator releases the PTT button. Releasing the PTT button
resets the timer.
CHANNEL BUSY LOCK-OUT
If the radio is receiving a signal when the PTT button is pressed, a beep
will warn the operator that the radio is receiving a carrier and the
transmission will not occur. The beep is sounded as long as the PTT
button is pressed. The channel-busy feature is programmable on or off
on a per-channel basis.
Type 99 decode and Channel Busy Lock-Out are mutually exclusive. If
Channel Busy Lock-Out is programmed, T99 decode will not occur.
18

RECEIVE-ONLY CHANNEL
If the selected channel is programmed for receive-only, the radio will
beep if a transmission is attempted.
TYPE 99 ALERT TONE
The Type 99 alert tone, indicating a receive Type 99 call, may be
enabled or disabled by PC programming. If the alert tone is enabled, the
level may also be programmed to sound at the present volume control
setting or at maximum volume, regardless of volume control setting. If
the alert tone is disabled, no alert tone will be present when a Type 99
call is received.
ANI ALERT TONE
The ANI (Automatic Number Identification) alert tone beep can be
enabled or disabled by PC programming. If the alert tone is enabled, a
beep will sound after the PTT is pressed, to indicate to the user to begin
voice transmission. Some communication systems require a time delay
before voice transmission begins. If the alert tone is disabled, no beep
will be sounded.
19

PRIORITY-ONE (P1) SCAN
If the radio receives a signal on the Priority 1 channel when scanning,
the radio will sound a beep if the Priority 1 alert tone is programmed on.
RADIO/CHANNEL FAILURE
The simultaneous flashing of the "BAT" status indicator and the
sounding of beeps indicates the synthesizer is unable to correctly lock
on the selected channel. If this happens when transmitting,
transmissions are inhibited (no transmission is made). Select another
channel, change the battery pack, or have the radio repaired.
OPERATION
RECEIVING A MESSAGE
1. Turn the radio on by sliding the ON/OFF switch on the
battery pack to the "ON" position. A yellow area will be
visible. After the radio has successfully completed its
power-up self-test, it will begin operation at the last
operating state (channel, volume, etc.). The operating
status of the radio will be displayed in the LCD window.
If programmed on, the power-up alert tones (three or four
beeps) will be sounded.
