PREPARATION
■Charging the Optional NiCd Battery Pack
The optional battery pack is not charged at the
factory; charge it before use (refer to the battery
pack instruction manual).
◆ DO NOT RECHARGE THE BATTERY PACK IF IT IS
ALREADY FULLY CHARGED. DOING SO MAY CAUSE THE
LIFE OF THE BATTERY PACK TO SHORTEN OR THE
BATTERY PACK MAY BE DAMAGED.
◆ AFTER RECHARGING THE BATTERY PACK, DISCONNECT
IT FROM THE CHARGER. IF THE CHARGER POWER IS
RESET (TURNED ON AFTER BEING TURNED OFF),
RECHARGING WILL START AGAIN AND THE BATTERY
PACK WILL BECOME OVERCHARGED.
Initially charging the battery pack after purchase or
extended storage (greater than 2 months) will not
bring the battery pack to its normal operating
capacity. After repeating the charge/discharge cycle
two or three times, the operating capacity will
increase to normal.
■Installing/ Removing the Optional NiCd Battery Pack
Only use the KNB-14 and KNB-15A battery packs
with this transceiver.
◆ DO NOT SHORT THE BATTERY TERMINALS OR DISPOSE
OF THE BATTERY BY FIRE.
◆ NEVER ATTEMPT TO REMOVE THE CASING FROM THE
BATTERY PACK.

1Match the four grooves
of the battery pack with
the corresponding
guides on the back of
the transceiver.
2Slide the battery pack
along the back of the
transceiver until the
release latch on the
base of the transceiver
locks.
3To remove the battery
pack, pull back on the
release latch and slide
the pack away from the
transceiver.
Screw the antenna into the
connector on the top of the
transceiver by holding the
antenna at its base and
turning it clockwise until
secure.

5
■Installing the Belt Clip
If necessary, attach the belt
clip using the two supplied
3 x 8 mm screws.
Note: If the belt clip is not installed,
its mounting location may get hot
during continuous transmission or
when left sitting in a hot
environment.
If you are not using an
optional speaker/
microphone, install the
cover over the SP/MIC
jacks using the supplied
3 x 6 mm screw.
■Installing the Cap over the Speaker/ Microphone Jacks
■Installing the Optional Speaker/ Microphone

OPERATING BASICS
■Switching Power ON/OFF
Turn the Power switch/ Volume control clockwise to
switch the transceiver ON.
Turn the Power switch/ Volume control counter-
clockwise to switch the transceiver OFF.
If the Radio Password function is programmed,
“PASSWORD” will appear on the display when the
power is turned ON. To unlock the transceiver, enter
the password, then press the Okey. If you enter the
wrong password, an error tone sounds and the
transceiver remains locked. The password can
contain a maximum of 6 digits.
■Adjusting the Volume
Rotate the Power switch/ Volume control to adjust
the volume. Clockwise increases the volume and
counterclockwise decreases it.
•You may need to adjust the volume more precisely
while communicating with other parties.
Note: If your dealer programmed Squelch Momentary or Squelch Off
onto a PF key, you can press that key to hear background noise while
adjusting the volume level (refer to “Monitor/Squelch” on page 29).
■Selecting a Group or Channel
Rotate the Rotary encoder (or press the keys
programmed as Group Up/Down or Channel Up/
Down) to choose your desired group or channel.
Clockwise increases the number and counter-
clockwise decreases it.
•If a group or channel has not been programmed, it
cannot be used.

11
■Adjusting the Squelch Level
Squelch is used to silence the speaker when no
signals are present. When squelch is turned OFF,
you will hear background noise from the speaker.
When it is ON, you will not hear background noise.
The squelch level you select determines when
squelch will turn OFF and ON. If you select a
squelch level that is too high, you will not hear
weaker signals. If you select a squelch level that is
too low, you will hear background noise between
signals.
To adjust the squelch:
1Press and hold the Side 2 key, then press the ss
ss
s
key.
•“SQL” and the current squelch level appear.
2Rotate the Rotary encoder to select a squelch
level from 0 ~ 9.
•Clockwise increases the squelch level and
counterclockwise decreases it.
3Press any key other than the key programmed as
Lamp to complete the setting.
•Normal operation is restored.

12
■Placing a Call
1Make sure no parties are currently transmitting on
your selected channel.
2Press the PTT switch and speak into the
microphone in your normal speaking voice.
•For best sound quality at the receiving station, hold
the microphone approximately 1.5 inches
(3 ~ 4 cm) from your mouth.
3Release the PTT switch to receive.
■Receiving a Call
Your dealer may have programmed QT or DQT
signalling on your transceiver. If your selected
channel is programmed with one of these features,
you will hear calls only when another party in your
system makes a call. All other calls will not be
heard.
If your selected channel is not set up with QT or
DQT, you will hear calls made by any party (not just
those in your system).

13
CHANNEL SCAN
Scan is useful for monitoring signals on the channels
programmed on the transceiver. When scanning, the
transceiver checks for a signal on each channel, and
only stops on a channel if a signal is present.
The transceiver will remain on a busy channel until the
signal is no longer present. Your dealer programs the
delay time between signal drop-out and scan
resumption. If a signal is received during the delay
time, the transceiver will remain on the same channel.
Note:
◆ You can only use Scan if your dealer has programmed at least 2
channels on the transceiver. Also, there must be at least 2 channels
not locked out of Scan.
◆ Ask your dealer for an explanation on how Channel Scan functions
when using Code Squelch, Selective Call, or 2-Tone signalling.
To start scanning, press the key programmed as Scan.
•Scanning starts from the current channel and ascends
through the channel numbers.
•The SCN icon and “SCAN” appear on the display.
To end Scan, press the Scan key again.

14
■Priority Scan
If your dealer set up a priority channel on your
transceiver, the transceiver will continuously monitor
that channel while receiving a signal on another
channel. When a signal is received on the Priority
channel, the transceiver immediately switches to that
channel.
•“P” appears on the display.
The transceiver will remain on the Priority channel
until the signal drops out. Your dealer programs the
delay time between signal drop-out and scan
resumption.
■Channel Lockout
If programmed by your dealer, you can select
channels to lock out of the scanning sequence.
Perform the following steps while not in Scan mode.
1Rotate the Rotary encoder to select the channel
you want to lock out of Scan.
2Press the key programmed as Scan Del/Add.
•Each press of Scan Del/Add toggles the lockout
status of the selected channel ON and OFF.
•Channels that are included in Scan are represented
by an “A” on the display. Channels locked out of
Scan do not have an “A” on the display.
■Revert Channel
During Scan, pressing the PTT switch to transmit will
cause the transceiver to select the revert channel.
Your dealer programs the Revert channel for your
transceiver. Consult your dealer for details.
