INTRODUCTION
The 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)

5
• Channel Guard Encode/Decode (Tone or Digital)
• Type 99 Tone Decode
• 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
receive 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" operation,
pressing it unsquelches the
receiver for the first three (3)
seconds the button is held. All
transmission will be heard, even if
Channel Guard protected. This
allows channel monitoring 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).

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 receive 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. The relative
volume level is indicated in the
LCD window by four (4) bars.

The 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 (∇∇) button.
The channel number will be
displayed in the LCD window.

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:
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).
NOTE

(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 procedures and Figure 2
for more details.
HOME CHANNEL
SELECTION/
EMERGENCY
MODE
The HOME/EMERGENCY button,
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.

15
(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 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.

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.

20
Type 99 decode and Channel Busy Lock-Out are
mutually exclusive. If Channel Busy Lock-Out is
programmed, T99 decode will not occur.
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.
