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.
PREPARATION

◆After the battery pack is charged, do not unplug and plug the
charger into the AC outlet again. Unpluging 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.
Charger Error
• While charging, if a problem is detected in the battery,
“Charge Error !!” appears on the display.
• The following conditions create charging errors:
• A short in the battery is detected.
• Overvoltage in the battery is detected.
• When a charge error occurs, no key other than []will
function.
BATTERY LIFE
Before you operate the transceiver outside using a battery
pack, it is important to know how long the battery pack
will last. The operating times listed in the table below are
measured under the following cyclic conditions:
TX: 6 seconds, RX: 6 seconds, Stand-by: 48 seconds
We recommend you carry extra battery packs with you, in
case the battery pack becomes depleted.

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.
