supply to actively eliminate the battery hysteresis.) Then, turn on the device, and it can work normally.

Note:

Please do not disassemble the device unless it is required to replace the batteries.

Do not touch the waterproof gasket when replacing the batteries.

to ensure the device is impermeable.

Kindly pay attention to the following in order to achieve the best maintenance of the product:

⚫ Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic circuits. If the device gets

wet, please dry it completely.

⚫ Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.

⚫ Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy

batteries, and deform or melt some plastic parts.

⚫ Do not store the device in places that are too cold. Otherwise, when the temperature rises to normal temperature, moisture will

form inside, which will destroy the board.

⚫ Do not throw, knock or shake the device. Rough handling of equipment can destroy internal circuit boards and delicate

structures.

⚫ Do not clean the device with strong chemicals, detergents or strong detergents.

⚫ Do not apply the device with paint. Smudges might block in the device and affect the operation.

⚫ Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.

All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the nearest

authorized service facility for repair.
