3.5 Maintenance
A frequent use makes the device surfaces, especially the keyboard, dirty. Use a piece
of soft cloth damped with clean water to remove the dirt. You are recommended to
follow the instructions below while cleaning:
Do not use aggressive detergents (such as sand or strong surfactants).
Clean at dry weather to make penetrated water, if any, dry up quickly.
