Cleaning
To clean your keyboard, gently wipe the keycaps and surface with a soft, dry, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water or a mild, non-abrasive cleaning solution. Avoid excessive moisture and do not submerge the keyboard in liquid.
Battery Care
If the keyboard will not be used for an extended period, it is recommended to remove the AAA batteries to prevent potential leakage and damage to the device.
