Safety Precautions
DANGER
Rechargeable Li-ion Battery (The rechargeable Li-on battery comes with the
PT-H300LI. Li-ion battery optional with the PT-H300).
Carefully observe the following precautions for the rechargeable Li-ion battery
(hereafter referred to as "rechargeable battery"), If these precautions are not followed,
overheating, leaking, or cracks in the battery may result in an electrical short,
explosion, smoke, fire, electric shock, injury to yourself or others, or damage to the
product or other property.
Use the rechargeable battery only for its
intended purpose. The labeler and
rechargeable battery are designed to
function exclusively with each other. Do
not insert a different rechargeable
battery into the labeler or insert the
rechargeable battery into a different
labeler, otherwise fire or damage may
result.
To charge the rechargeable battery,
insert the rechargeable battery into the
labeler, and then use the AC adapter
designed specifically for this labeler.
DO NOT charge the rechargeable
battery near a fire or in direct sunlight.
This could activate the protection
circuitry, which is designed to prevent
danger from high heat. Activation of the
protection circuitry could cause charging
to stop, charging to occur with excessive
current or voltage if the protection
circuitry fails, or an abnormal chemical
reaction within the battery.
When charging the rechargeable
battery, use only a battery charger
designed specifically for the
rechargeable battery.
DO NOT allow wires or other metal
objects to come into contact with the
terminals of the rechargeable battery.
Do not carry or store the rechargeable
battery with metal objects such as
necklaces or hairpins. This could cause
an electrical short, and could cause
metal objects to overheat, such as wires,
necklaces, or hairpins to overheat.
DO NOT use or leave the rechargeable
battery near fire, heaters, or other high
temperature (above 176 ° F/80 ° C)
locations.
DO NOT allow the rechargeable battery
to come into contact with or to be
immersed in water.
DO NOT use in corrosive environments,
such as areas where salty air, salt water,
acids, alkalis, corrosive gases,
chemicals, or any corrosive liquid are
present.
DO NOT use the rechargeable battery if
it is damaged or leaking.
DO NOT directly solder any connections
to the rechargeable battery. This could
cause internal insulation to melt, gas to
be emitted, or safety mechanisms to fail.
DO NOT use the rechargeable battery
with the polarity (+) (-) reversed. Check
the orientation of the rechargeable
battery before inserting it, and do not try
to force the rechargeable battery into the
labeler. Charging the rechargeable
battery with the polarity reversed could
cause an abnormal chemical reaction
within the rechargeable battery or
abnormal current flow during discharge.
DO NOT directly connect the
rechargeable battery to a household.
