Rechargeable battery (Lithium polymer ion)
To reduce the risk of fire, electric shock or product damage,
• Do not attempt to replace the battery by yourself, it is built-in and is not
changeable.
• Do not heat, disassemble, or short-circuit the battery. Doing so may cause the
battery and power supply to generate heat, rupture, or ignite.
• Charge the battery only in an ambient temperature between 5 and 35 degrees
Celsius. Otherwise, the electrolyte solution might leak, battery performance
might deteriorate and the battery life might be shortened.
• Do not continue charging the battery if it does not reach full charge within the
specified charging time. Overcharging may cause the battery to become hot,
rupture, or ignite.
• Do not expose the battery to excessive heat such as under the sun or near the fire
or the like.
Overheat, leakage, or rupture may occur, resulting in burns or injury.
If you touch the battery fluid, rinse it off with water and consult with the doctor. If the
battery fluid spills over the device, wipe it off without touching the fluid.
If you leave the unit unused for a long period of time, the built-in rechargeable battery
will be in an over discharge state due to self discharge, and the charging capacity may
deteriorate or the battery may be no longer rechargeable. Even if you are not using the
unit, charge the battery once or twice a year for 3 hours each time.
