If you have not used the product for a long time, you should charge the battery.
• At extremely high or low temperatures, such as if you leave the product in a closed car during summer, the capacity of
the internal battery decreases and so will the amount of time it can be used decreases. This also decreases the lifespan

long time, you should charge the battery as the internal battery may have discharged.

after each charge has become extremely short), stop using the battery as it is at the end of its service life. As the battery
is built-in, you can have it replaced at an au shop for a fee. Note that you will not be able to use the product for a certain
period of time. The battery lifespan varies depending on how the product is used.
• Depending on the use condition, the internal battery may be inflated as it comes close to the end of its service life. This is
due to the properties of lithium-ion battery and does not pose any safety risks.
