INSTALLING THE ANTENNA
Hold the supplied antenna by its base, then screw it into the
connector on the top panel of the transceiver until secure.
INSTALLING THE BATTERY PACK
Note:
◆Because the battery pack is provided uncharged, you must
charge the battery pack before using it with the transceiver.
Match the guides of the battery pack with the corresponding
grooves on the upper rear of the transceiver, then firmly press
the battery case to lock it in place.
To remove the battery pack, lift the release lever to unlock the
battery pack. Lift the battery pack away from the transceiver.
INSTALLING ALKALINE BATTERIES
1To open the optional KBP-9 battery case lid, press the
release lever on the top of the battery case, then pull the
cover up.

2Insert (or remove) six AAA (LR03) Alkaline batteries.
• WhenremovingtheAlkalinebatteriesfromthebattery
case, pull up on the batteries from the positive (+)
terminal.
• Besuretomatchthebatterypolaritieswiththose
marked in the bottom of the battery case.
3Align the two tabs at the bottom of battery case, then
close the cover until the locking tabs on top click.
4To install the battery case onto (or remove it from) the
transceiver, follow “INSTALLING THE BATTERY PACK”.
Note:
◆Do not use Manganese batteries or Rechargeable batteries in
place of Alkaline batteries.
◆Remove all batteries from the case when it is not expected to
be in use for several months.
◆To lift the battery pack safety catch, use a piece of hardened
plastic or metal, such as a screwdriver, that is no more than
6 mm wide and 1 mm thick. It is imperative that you place the
implement under only the lip of the safety catch so that you do
not damage the release latch.

3-2
INSTALLING THE BELT CLIP
If desired, you can install the supplied belt clip to the
transceiver.
Attach the belt clip firmly using the two supplied M3 x 6 mm
binding screws.
Note：
◆Be careful not to pinch your fingers into the belt clip.
CAUTION
• 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.
INSTALLING THE HAND STRAP
If desired, you can install the commercially available strap
with sufficient strength using the holes of the transceiver.
Note：
◆If the strap is thick and does not pass through the holes, install
the strap using the holes of the supplied belt clip.
CHARGING THE BATTERY PACK
The battery pack can be charged after it has been installed
onto the transceiver. (The battery pack is provided uncharged
for safety purposes.)
1Confirm that the transceiver power is OFF.
• Whilechargingthebatterypack,leavethetransceiver
power OFF.
2Insert the charger plug into the DC-IN jack of the
transceiver.

• Chargingstartsand“Charging”appearsonthedisplay.
• “Charging”disappearswhenchargingiscompleted.
• ThebacklightisONwhenpressinganykeywhile
charging.
• “Charging”doesnotappearwhenchargingwiththe
optional KSC-25LS.
4It takes approximately 3.5 hours to charge an empty
KNB-75L Li-ion battery pack. After 3.5 hours, remove the
charger plug from the transceiver DC-IN jack.
5Unplug the charger from the AC wall outlet.
Note:
◆Never leave the battery pack in direct sunlight.
◆The transceiver becomes warm while charging the battery pack.
◆While the battery pack is charged, the ambient temperature
must be within 0°C ~ 40°C (32°F ~ 104°F). Otherwise,
charging does not start. If the transceiver senses that the
temperature is more than 60°C (140° F) during charging, the
transceiver stops charging.
◆Before recharging the battery pack, use the battery pack until
the transceiver stops receiving.
◆Do not plug the charger into the DC-IN jack for more than 24 hours.
◆Do not expose the charger to dripping or splashing conditions.
No objects filled with liquids, such as vases, shall be placed on
the AC adapter or charger.
◆Do not place the charger into the liquids.
◆Unplug the charger as soon as possible after the charging
period is over.
◆The charger plug for an AC wall outlet should be used to
disconnect an AC adapter from an AC outlet, and the charger
plug must remain readily operable.
◆After the battery pack is charged, do not unplug and plug the
charger into the AC outlet again. Unplugging the charger will
reset the charging timer and the battery pack will be charged
again. This could result in over-charging.
◆When the battery is installed on the transceiver and you are
using an optional rapid battery charger, do not charge the
battery from the DC-IN jack. Charging the battery from the
DC-IN jack may result in overcharging the battery which can
result in the shortening of the battery life cycle.
◆If the battery pack is not used for a long time, the battery
pack capacity temporarily decreases. In this case, charge the
battery and use the battery pack until the transceiver stops
receiving. Repeat this procedure several times. The battery
pack should recover its capacity.
◆If the charger is plugged into the DC-IN jack before the battery
pack is attached, turn the transceiver power ON and then OFF
again to initiate charging.
◆Exceeding the specified charge period shortens the useful life
of the KNB-75L battery pack.
◆The provided charger is designed to charge only the KNB-75L
battery pack. Charging other models of battery packs may
damage the charger and battery pack.
◆Do not transmit while charging.
◆When not in use, store the battery pack in a cool and dry place.
◆Before charging the battery pack, ensure that the release lever
is firmly closed.
◆Attention should be drawn to the environmental aspects of
battery disposal.
◆It takes approximately 3 hours to charge the KNB-75L with the
optional KSC-25LS.

CONNECTING TO A CIGARETTE LIGHTER SOCKET
To connect the transceiver to the cigarette lighter socket in
your vehicle, use an optional PG-3J Cigarette Lighter cable.
When the PG-3J is connected to the cigarette lighter plug,
the transceiver automatically starts charging the battery pack.
While you operate the transceiver, it charges the battery pack
in the background.
Note:
◆To connect with an external 24 V power source via a DC-DC
converter, only use the optional PG-3J Cigarette Lighter cable.
◆Using the PG-2W DC cable in this situation may cause a fire.

transceiver.
◆If the input voltage exceeds approximately 17.5 V, the
transceiver automatically turns OFF.
CONNECTING TO A REGULATED POWER SUPPLY
To connect the transceiver to an appropriate regulated DC
power supply, use an optional PG-2W DC cable.
1Confirm that the power of both the transceiver and the DC
power supply is OFF.
2Connect the optional PG-2W DC cable to the DC power
supply; the red lead to the positive (+) terminal, and the
black lead to the negative (–) terminal.

3Connect the barrel plug on the DC cable to the DC IN jack
of the transceiver.
• WhileaDCpowersupplyisconnectedwiththeDCIN
jack, the transceiver automatically initiates charging the
battery pack.
Note:
◆The supply voltage must be between 12.0 V and 16.0 V to
prevent damaging the transceiver. If the input voltage exceeds
approximately 17.5 V, the transceiver automatically turns OFF.
