SAFETY PRECAUTIONS
IX
CAUTION
Do not disassemble or modify the battery pack. The battery pack has built-in safety and
protective functions designed to prevent danger. If these functions are damaged, the
battery fluid may leak from the battery pack, resulting in heat generation, smoke, explosion
or fire.
Do not connect the “+” and “−” terminals of the battery pack with metal objects like a wire.
In addition, do not carry the battery pack or store it near metal necklaces or hairpins. Doing
so may short-circuit the battery pack. This may cause excessive current flow, resulting in
leakage, heat generation, smoke, explosion or fire, or may cause the metal objects,
necklaces or hairpins to generate heat.
Do not put the battery pack into a fire or heat it. Doing so may melt insulating materials,
damage the protective circuit, or cause the battery fluid to catch fire, resulting in leakage,
heat generation, smoke, explosion or fire.
Do not use or leave the battery pack near a fire or hot objects such as stoves. Doing so
may cause short-circuit in the battery pack, resulting in battery fluid leakage, heat
generation, smoke, explosion or fire.
Do not put the battery pack under any water, including seawater, or let it get wet. If the
built-in protective circuit is damaged, the battery pack will be charged with abnormal current
or voltage. This may cause a chemical reaction inside the battery pack, resulting in battery
fluid leakage, heat generation, smoke, explosion or fire.
Do not charge the battery pack near a fire or under very hot sunshine. If it gets hot, the
protective device will initiate to prevent danger, hindering charging, or it gets damaged
causing charging with abnormal current or voltage. Such charging may cause a chemical
reaction inside the battery pack, resulting in battery fluid leakage, heat generation, smoke,
explosion or fire.
Charging of the battery pack must be performed on this instrument under the specified
charging conditions. If charging is performed in an environment that does not conform to
the specified charging conditions (e.g. at excessively high temperatures, with higher
voltage/current than the specified, using a modified charger), the battery pack may be
excessively charged, or charged with abnormal current. Such charging may cause an
abnormal chemical reaction inside the battery pack, resulting in battery fluid leakage, heat
generation, smoke, explosion or fire.
Do not pierce the battery pack with a nail, hit it with a hammer, or stamp on it. Doing so
may damage or deform the battery pack. This may cause short-circuit inside the battery
pack, resulting in battery fluid leakage, heat generation, smoke, explosion or fire.
Do not cause any excessive impact to the battery pack or throw it. Doing so may result in
battery fluid leakage, heat generation, smoke, explosion or fire.
Furthermore, if the built-in protective circuit is damaged, the battery pack will be charged
with abnormal current or voltage. This may cause an abnormal chemical reaction inside the
battery pack, resulting in battery fluid leakage, heat generation, smoke, explosion or fire.
Do not solder directly on the battery pack. Doing so may melt insulating materials, damage
the protective circuit, resulting in battery fluid leakage, heat generation, smoke, explosion
or fire.
Do not use the battery pack if it shows excessive damage or deformation. Using it in such
condition may result in battery fluid leakage, heat generation, smoke, explosion or fire.
