Maintenance and Care
To ensure the longevity and optimal performance of your Astrum ELETE Combe UB combo, follow these maintenance guidelines:
- Cleaning:
- Disconnect the keyboard and mouse from your computer before cleaning.
- Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Avoid harsh chemicals, abrasives, or solvents.
- For the keyboard, you can use compressed air to remove dust and debris from between the keys.
- For the mouse, clean the optical sensor area periodically to ensure smooth tracking.
- Spill Resistance: While the keyboard is spill-resistant, it is not waterproof. In case of a spill, immediately disconnect the keyboard, wipe off the liquid, and allow it to dry completely before reconnecting.
- Storage: Store the combo in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
- Handling: Avoid dropping the devices or subjecting them to strong impacts. Do not attempt to disassemble the keyboard or mouse, as this will void the warranty.
