To clean the numpad, gently wipe the surface and keycaps with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the ABS and PC keycaps or the transparent casing. Ensure the device is powered off and disconnected from any power source before cleaning.

Догляд за акумулятором

The numpad is equipped with a rechargeable Lithium Polymer battery. For optimal battery life, avoid fully discharging the battery frequently. Recharge the numpad when the battery indicator is low. If storing the numpad for an extended period, charge it to approximately 50% and store it in a cool, dry place.

• Проблеми з підключенням Bluetooth: Make sure Bluetooth is enabled on your device. Unpair and re-pair the numpad. Ensure no other devices are interfering with the Bluetooth signal. Try connecting to a different Bluetooth channel if available.
