■
In case of obvious deformation, seepage or peculiar smell at the installation place of the battery pack,
the device shall not be further used, and distributor shall be contacted immediately for assistance.
■
Do not use the device beyond its temperature range; otherwise, the service life of the device and
battery pack may be reduced or damaged.
■
Do not leave the battery pack in fully charged or fully discharged state for a long time. Otherwise, the
service life of battery pack will be shortened.
Please maintain the electric quantity of battery pack within
40%~50% if the device is to be left unused for a long time, and then keep it properly.
■
The service life of the built-in battery pack is about 3~4 years generally. Please replace the battery
pack once its service life reaches this period.
Even if the battery still works, its performance will be
significantly reduced and service time will be greatly shortened.
The battery pack can be generally charged
and discharged for 300~500 times.
This depends on specific usage conditions.
