■Charging the NiCd Battery Pack
The battery pack is not charged at the factory;
charge it before use.
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.
◆ 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. CHARGING THE
BATTERY PACK FOR MORE THAN 5 DAYS MAY REDUCE
THE BATTERY PACK LIFE DUE TO OVERCHARGING.
Note:
◆ The ambient temperature should be between 41 and 104 ° F
(5 and 40 ° C) while charging is in progress. Charging outside
this range may not fully charge the battery.
◆ Always switch OFF the transceiver equipped with a NiCd battery
pack before charging. Using the transceiver while charging its
battery pack will interfere with correct charging.
◆ The battery pack life is over when its operating time decreases
even though it is fully and correctly charged. Replace the
battery pack.
PREPARATION

4
Note: It takes approximately 6 hours to fully charge the optional
KNB-14 battery pack.
Plug the AC adaptor cable into
the adaptor jack located on the
rear of the charger.
Plug the AC adaptor into an AC outlet.
Slide the NiCd battery pack or
transceiver with a NiCd battery
pack into the charger.
• Make sure the battery pack
contacts are in contact with the
charging terminals.
• The charger LED lights and
charging begins.
After charging the supplied KNB-15A battery pack
for 8 hours, remove it or the transceiver equipped
with it from the charger.
• The charger does not turn OFF automatically after
charging is completed.
Unplug the AC adaptor from the AC outlet.

5
■Installing/ Removing the Battery Pack
The average life of the supplied KNB-15A NiCd
battery pack is 8 hours. Average times are
calculated using 5% transmit time, 5% receive time,
and 90% standby time.
◆ DO NOT SHORT THE BATTERY TERMINALS OR
DISPOSE OF THE BATTERY BY FIRE.
◆ NEVER ATTEMPT TO REMOVE THE CASING FROM THE
BATTERY PACK.
Match the four grooves of
the battery pack with the
corresponding guides on
the back of the transceiver.
Slide the battery pack
along the back of the
transceiver until the
release latch on the base
of the transceiver locks.
To remove the battery
pack, pull back on the
release latch and slide
the pack away from the
transceiver.

■Installing the Antenna
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.
Note: The antenna is neither a handle,
a key ring retainer, nor a speaker/
microphone attachment point. Using
the antenna in these ways may damage
the antenna and degrade your
transceiver’s performance.

■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.
◆ You must remove the belt clip
before removing the battery pack.
DO NOT USE GLUE WHICH IS DESIGNED TO PREVENT
SCREW LOOSENING WHEN INSTALLING THE BELT CLIP, AS
IT MAY CAUSE DAMAGE TO THE TRANSCEIVER. ACRYLIC
ESTER, WHICH IS CONTAINED IN THESE GLUES, MAY
CRACK THE TRANSCEIVER’S BACK PANEL.

If you are not using a speaker/
microphone, install the cover
over the speaker/ microphone
jacks using the supplied

microphone jacks with the supplied
cover.
■Installing the Cover over the Speaker/ Microphone Jacks
■Installing the Optional Speaker/ Microphone

AUXILIARY FUNCTIONS
■Time-out Timer
The purpose of the Time-out Timer is to prevent any
single person from using a channel for an extended
period of time.
If you continuously transmit for 10 minutes, the
transceiver will stop transmitting and a tone will
sound. To stop the tone, release the PTT switch.
You can press the PTT switch again to resume
transmitting.
■Battery Save
The Battery Save function decreases the amount of
power used when a signal is not being received and
no operations are being performed (no keys are
being pressed, and no switches are being turned).
While the channel is not busy and no operation is
performed for 10 seconds, Battery Save turns ON.
When a signal is received or an operation is
performed, Battery Save turns OFF.
■Low Battery Warning
Low Battery Warning alerts you when the battery
needs to be recharged.
While transmitting, if the battery power goes below a
pre-determined value, the LED will blink red. When
a tone sounds, the transceiver stops transmitting.
Replace or recharge the battery pack.

13
■Monitor
When no signals are present, the squelch on the
transceiver automatically mutes the speaker so you
will not hear background noise. To manually
deactivate the squelch, press and hold the Monitor
key. This is useful when you want to adjust the
volume level, or when you need to hear a weak
signal.
• The LED indicator lights green while the Monitor key
is pressed.
■Quiet Talk (QT) and Digital Quiet Talk (DQT)
Some channels may have pre-programmed QT/DQT
tones. A QT/DQT tone is a subaudible tone which
allows you to ignore (not hear) calls from other
parties who are using the same channel.
When you receive a signal that has a tone different
from the one set up in your transceiver, you will not
hear the signal. Likewise, signals that you transmit
will only be heard by parties whose QT/DQT tone
matches the tone set up in your transceiver.
Note: Although using channels set up with QT/DQT tones relieves
you from listening to unwanted calls, it does not mean your calls will
be private.
