- For deeper cleaning, keycaps can be carefully removed and cleaned with mild soap and water, then thoroughly dried before reattaching.
5.2. Storage
- Store the keyboard in a cool, dry place when not in use.
- Avoid bending or pulling the 3.5mm audio cable or USB-C cable excessively.
- Cover the keyboard with a dust cover if not in use for an extended period to prevent dust accumulation.
5.3. Inspection
