Battery Life; Installing The Belt Clip; Installing The Hand Strap - Kenwood TH-D74E User Manual

◆ 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 specifi ed 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
fi rmly 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.

"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

BATTERY LIFE

Before you operate the transceiver outside using a battery
pack, it is important to know how long the battery pack

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 fi rmly using the two supplied M3 x 6 mm
binding screws.
Note ：
◆ Be careful not to pinch your fi ngers 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 suffi cient 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.
