forms of damage to the battery. Please observe the following
safety precautions.
DANGER
• Do not disassemble or rebuild the battery!
The battery pack has a safety and protection circuits
to avoid danger. If they suffer serious damage, the
battery may generate heat or smoke, rupture, or burst
into flame.
• Do not short-circuit the battery!
Do not join the + and – terminals using any form of
metal (such as a paper clip or wire). Do not carry
or store the battery pack in containers holding metal
objects (such as wires, chain-necklace or hairpins). If
the battery pack is short-circuited, excessive current
will flow and the battery may generate heat or smoke,
rupture, or burst into flame. It will also cause metal
objects to heat up.
• Do not incinerate or apply heat to the battery!
If the insulator is melted, the gas release vent or safety
circuit is damaged, or the electrolyte is ignited, the
battery may generate heat or smoke, rupture, or burst
into flame.
• Do not leave the battery near fire, stoves, or other
heat generators (areas reaching over 80°C/ 176°F)!
If a cell internal polymer separator is melted due to
high temperature, an internal short-circuit may occur in
the individual cells and the battery may generate heat
or smoke, rupture, or burst into flame.
• Avoid immersing the battery in water or getting it
wet!
If the battery becomes wet, wipe it off with a dry
towel before use. If the battery’s protection circuit is
damaged, the battery may charge at excess current
(or voltage) and an abnormal chemical reaction may
occur. The battery may generate heat or smoke,
rupture, or burst into flame.
• Do not charge the battery near heat sources, fires
or in direct sunlight!
If the battery’s protection circuit is damaged, the
battery may charge at excess current (or voltage) and
an abnormal chemical reaction may occur. The battery
may generate heat or smoke, rupture, or burst into
flame.
• Use only the specified charger(s) and observe
charging requirements!
If the battery is charged in out of specifications
conditions (at high temperature over the specified
value, excessive high voltage or current over the
specified value, or with a modified charger), it may
overcharge or an abnormal chemical reaction may
occur. The battery may generate heat or smoke,
rupture, or burst into flame.
• Do not pierce the battery with any object, strike it
with an object, or step on it!
This may break or deform the battery, causing a
short-circuit. The battery may generate heat or smoke,
rupture, or burst into flame.
• Do not jar or throw the battery!
An impact may cause the battery to leak, generate

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.
3 Plug the charger into an AC wall outlet.
• 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.
4 It 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.
5 Unplug 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.
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.
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
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.
• 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.
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.

APRS DATA COMMUNICATION
• This function uses the APRS format for data
communications including your station position, messages,
etc.
• When data is received from another station directly, via
digipeaters and/or IGate stations, the direction of the
received station (from your station’s perspective), their
distance, and their grid square locator is displayed. Any
comments sent by the other stations are also displayed.
• APRS (Automatic Packet Reporting System) is a
worldwide system introduced by Bob Bruninga, WB4APR.
< APRS® is a software program and registered trademark
of Bob Bruninga, WB4APR.>
Official APRS Website: http://www.aprs.org
APRS Network
Digipeater
• Digipeater (Digital Repeater) relays digital packet data.
When a Digipeater receives a packet, it saves it to
memory. When the reception ends, the packet data is retransmitted on the same frequency. Using Digipeaters, it is
possible to exchange APRS packets long distances.
IGate
• IGate (Internet Gateway) is a very useful and important
feature for APRS as well as Digipeater. IGate stations
bridge APRS packets between RF and the Internet.
By going through the IGate stations, you can enjoy the
communication with the further distant stations which are
not covered only by Digipeaters.

D-STAR INTRODUCTION
• In the original D-STAR (Digital Smart Technologies for
Amateur Radio) plan, JARL envisioned a system of
repeaters grouped together into Zones.
• The D-STAR repeater enables you to call a D-STAR
station in another area through the internet.
• The transceiver can be operated in the digital voice mode,
including low-speed data operation, for both transmit and
receive.
Note:
◆ Before starting D-STAR, the following steps are needed.
STEP 1: Enter your Callsign in the transceiver.
STEP 2: Register your Callsign to a gateway repeater.
