■ Battery■pack ■
● Do not touch connection terminal with a cotton swab or other
sharp-pointed items. Since the connection terminal is made of
groove-shaped metal spring, materials other than terminal metal
might deform when being inserted and might not available to use.
● Use in very hot or cold environments, for example, when left in a
car with the windows closed in summer, will cause the battery
capacity to drop and shorten the available battery usage time.
This will also shorten the battery pack's service life. Try to use the
battery pack as far as possible at room temperature.
● When the battery pack is not to be used for a long time, remove
the battery pack from the main unit. Store it away from hot and
humid places.
● Charge the battery before using the product for the first time after
purchase, or if you have not used the product for a long time.
● The battery pack is a consumable item. If the performance of a
battery pack does not recover after charge, the battery pack is
at the end of service life, so buy a new one of the specified type.
Note that the length of service life varies depending on the usage
condition, etc.
● Do not discard battery packs together with regular trash. Please
cooperate in the collection of used battery packs to protect the
environment and effectively use resources. au shops and other
retailers collect used battery packs.
● Battery packs sometimes swell up as they approach the end
of their service life. This is due to the properties of lithium-ion
batteries, and is not a problem in terms of safety.
● When replacing battery pack, make sure to follow the specified
method. Any methods not specified when attaching or removing
battery pack might cause damage of battery pack or battery cover.
