INTRODUCTION
The KPC-300 (Scan) and KPC-400 (DTMF) portable
radios are lightweight, full-featured radios that provide
reliable two-way communications on 1 to 16 channels.
The KPC-300 radio contains three (3) buttons on the
front panel. The KPC-400 contains three (3) buttons
along with a twelve (12) button DTMF pad on the front
panel. The scan function allows monitoring of any or 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 (S). There is also Emergency mode transmis-
sion capability. A LCD display provides status display of
the radio functions along with the display of the selected
channel number.
The 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 dealer to determine the programmed
features of your radio. Features that are programmable
on a per-channel basis include:
•Receive Frequency
•Transmit Frequency
•Channel Busy Lock-Out
•Carrier Control Timer (CCT)
•Squelch Tail Elimination (STE)
•Channel Guard Encode/Decode (Tone or Digital)

tected. This permits channel moni-
toring before transmitting.If the but-
ton is held for more than three (3)
seconds, Channel Guard decode
will toggle ON or OFF (if it is pro-
grammed on the selected channel).
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.
CHANNEL
SELECT
- A rotary switch permits selection of

ALERTTONES
Alert tones or “beeps” are sounded when some but-
tons are pressed and when the operating status of the
radio changes.All alert tones may be programmed to be
remain off. Alert tones or "beeps" are at a fixed volume
level which cannot be changed by the volume control.
Power-up Self-test
Each time the radio is turned on, it will perform
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, etc.) and
sound three (3) or four (4) beeps.Three (3) beeps sound
if the radio is operating in the normal (not scan) state.
Four (4) 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
15

if the transmit timer limit is exceeded.If the programmed
timer times-out during a transmission, the radio will beep
andstoptransmitting.Thebeepingtonewillcontinueuntil
theoperator releases the PTT button.Releasingthe PTT
button resets the timer.
Channel Busy Lock-out
Ifchannelbusylock-outhasbeenprogrammedonthe
selected channel, the transmit function will be inhibited
when the operator press the PTT button while the radio
detects a carrier on the channel unless the carrier is
modulated with the corresponding Channel Guard tone
or code for that selected channel. Channel busy lock-out
continues to function if Channel Guard decode is dis-
abled with the MONITOR button.The channel-busy fea-
ture is programmable on a per-channel basis.
Type 99 Alert Tone
The Type 99 alert tone, indicating a receive Type 99
call, may be enabled or disabled by programming.If the
programmed tone sequence is detected the radio will
beep until the second paging tone expires. If the alert
toneisdisabled,noalerttonewillbepresentwhenaType
99 call is received.
ANI Alert Tone
The Automatic Number Identification (ANI) alert tone
beep can be enabled or disabled by programming.If the
alert tone is enabled, a beep will sound after the PTT is
pressed to indicate to the operator to begin voice trans-
mission. Some communication systems require a time
16

delay before voice transmission begins. If the alert tone
is disabled, no beep will sound.
Scan Alert Tone
The radio will sound a beep when the S button is
pressed.
Priority-One (P1) Scan
If the Priority 1 alert tone is enabled by programming
and the radio receives a signal on the Priority 1 channel
when scanning, the radio will sound a beep.
Radio/Channel Failure
The simultaneous flashing of theLCD displayand the
sounding of beeps indicates the synthesizer is unable to
correctly lock on the selected channel. At this time the
radio changes to a mute condition and no audio is heard
from the speaker when receiving and the transmit is
inhibited if the PTT button is pressed. Select another
channel, change the battery pack or have the radio
repaired.

Monitor mode is programmed and a Type 99 channel is
selected, the PG status flag will blink.
When the radio is operating in the Selective mode, it
operates as a tone and voice receiver and only those
calls that are coded for it will be heard.
When the radio is operating in the Monitor mode, all
calls (withcorrectChannelGuard,ifprogrammed)willbe
heard.
In either mode, when a Type 99 channel has been
selected and a valid code is received, a series of beeps
will alert the operator of the incoming call. If the radio is
in the Selective mode, it will automatically switch to the
Monitor mode after the detection of the second Type 99
