Device Maintenance

Please remember the following tips when you maintain your smart watch:

• Clean the smart watch regularly, especially its inner side, and keep it dry.
• Adjust the smart watch tightness to ensure air circulation.
• Excessive skincare product should not be used for the wrist wearing the smart watch.
• Please cease wearing the smart watch in case of skin allergy or any discomfort.

Why can not take a hot bath with the smartwatch?

The bath water has a relatively high temperature, and generates a lot of vapor which is in the gas phase with small molecular radius and can easily infiltrate into the smart watch from the shell gap. When the temperature drops down, the vapor will condensate into liquid-phase droplets which will easily cause the short circuit inside the smart watch and damage the circuit board and then damage the smartwatch.
