Environmental protection
When the electric toothbrush reaches its service life, the internal battery may need to
be removed and properly recycled according to the laws and regulations of the
country or region where it is located. If the battery cannot be removed, please turn
the product to the recycling center designated by the government.
Change Brush Head
Make sure that the direction of the bristles of the toothbrush head is consistent
with the front direction of the toothbrush handle, and install the brush head
vertically downwards on the handle, and ensure that there is a certain gap of
0.5-0.8mm between the two components (to avoid the collision of the toothbrush
head with the handle in high-frequency vibration); Do not install the brush head
by twisting vigorously.(otherwise, the brush head and body may be damaged.)
