PREPARATION
BATTERY PACK PRECAUTIONS
◆ 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.
If the charger power is reset (turned ON after being turned OFF),
recharging will start again and the battery pack will become
overcharged.
◆ Do not use the transceiver while charging the battery pack. We
recommend you switch the transceiver power OFF while charging
is taking place.
◆ Do not short the battery terminals or dispose of the battery by
fire.
◆ Never attempt to remove the casing from the battery pack.
Information concerning the (optional) Li-ion battery pack:
The battery pack includes flammable objects such as organic solvent.
Mishandling may cause the battery to rupture producing flames or
extreme heat, deteriorate, or cause other forms of damage to the
battery. Please observe the following prohibitive matters.
DANGER
•Do not disassemble or reconstruct battery!
The battery pack has a safety function and protection circuit 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 paperclip 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.
2
•Do not incinerate or apply heat to the battery!
If the insulator is melted, the gas release vent or safety function is
damaged, or the electrolyte is ignited, the battery may generate
heat or smoke, rupture, or burst into flame.
•Do not use or leave the battery near fires, stoves, or other
heat generators (areas reaching over 80°C/ 176°F)!
If the 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.
•Do not immerse the battery in water or get it wet by other
means!
If the battery’s protection circuit is damaged, the battery may
charge at extreme 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 fires or under direct sunlight!
If the battery’s protection circuit is damaged, the battery may
charge at extreme 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 and observe charging
requirements!
If the battery is charged in unspecified conditions (under high
temperature over the regulated value, excessive high voltage or
current over regulated value, or with a remodelled 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
instrument, or step on it!
This may break or deform the battery, causing a short-circuited.
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 heat or smoke,
rupture, and/or burst into flame. If the battery’s protection circuit is
damaged, the battery may charge at an abnormal current (or
voltage), and an abnormal chemical reaction may occur. The
battery may generate heat or smoke, rupture, or burst into flame.
3
•Do not use the battery pack if it is damaged in any way!
The battery may generate heat or smoke, rupture, or burst into
flame.
•Do not solder directly onto the battery!
If the insulator is melted or the gas release vent or safety function
is damaged, the battery may generate heat or smoke, rupture, or
burst into flame.
•Do not reverse the battery polarity (and terminals)!
When charging a reversed battery, an abnormal chemical
reaction may occur. In some cases, an unexpected large amount
of current may flow upon discharging. The battery may generate
heat or smoke, rupture, or burst into flame.
•Do not reverse-charge or reverse-connect the battery!
The battery pack has positive and negative poles. If the battery
pack does not smoothly connect with a charger or operating
equipment, do not force it; check the polarity of the battery. If the
battery pack is reverse-connected to the charger, it will be
reverse-charged and an abnormal chemical reaction may occur.
The battery may generate heat or smoke, rupture, or burst into
flame.
•Do not touch a ruptured and leaking battery!
If the electrolyte liquid from the battery gets into your eyes, wash
your eyes out with fresh water as soon as possible, without
rubbing your eyes. Go to the hospital immediately. If left
untreated, it may cause eye-problems.
4
•Do not charge the battery for longer than the specified time!
If the battery pack has not finished charging even after the
regulated time has passed, stop it. The battery may generate
heat or smoke, rupture, or burst into flame.
•Do not place the battery pack into a microwave or high
pressure container!
The battery may generate heat or smoke, rupture, or burst into
flame.
•Keep ruptured and leaking battery packs away from fire!
If the battery pack is leaking (or the battery emits a bad odor),
immediately remove it from flammable areas. Electrolyte leaking
from battery can easily catch on fire and may cause the battery to
generate smoke or burst into flame.
•Do not use an abnormal battery!
If the battery pack emits a bad odor, appears to have different
coloring, is deformed, or seems abnormal for any other reason,
remove it from the charger or operating equipment and do not
use it. The battery may generate heat or smoke, rupture, or burst
into flame.
■ Using the Li-ion Battery Pack
•Charge the battery pack before using it.
•To keep the battery discharge at a minimum, remove the
battery pack from the equipment when it is not in use.
Store the battery pack in a cool and dry location.
•When storing the battery pack for a long period:
1 Remove the battery pack from the equipment.
2 Discharge the battery pack, if possible.
3 Store the battery pack in a cool (below 25°C/ 77°F)
and dry location.

■ Characteristics of the Li-ion Battery Pack
•As the battery pack is charged and discharged repeatedly,
the battery capacity decreases.
•Even if the battery pack is unused, the battery pack
degrades.
•It takes a longer time to charge the battery pack in cooler
areas.
•The life of battery pack is shortened when it is charged
and discharged in hotter areas. When the battery pack is
stored in a hot location, the battery pack degrades quicker.
Do not leave the battery pack in vehicles or near heating
appliances.
•When the battery pack operating time becomes short,
even if it is fully charged, replace the battery pack.
Continuing to charge and discharge the battery pack may
result in electrolyte leakage.
■ Charging the Li-ion Battery Pack
When charging a transceiver with a KNB-24L battery
pack, the safety catch of the battery pack may stick
out past the battery. When inserting the transceiver
with the battery pack into the charger, the safety
catch will touch the metal contacts of the charger
and the charger LED will momentarily light red. Be
sure to push the transceiver fully into the battery
pack slot so the safety catch no longer touches the
charger terminals. Once in place, the battery pack
will begin charging.
For charging procedures, refer to the KSC-25
Instruction Manual.
