As hands easily carry dirt, grime, oils, and moisture, we strongly recommend that users
wash hands prior to use to reduce dirt buildup inside the unit.
CLEANING
• Power off the unit and disconnect the power plug before any maintenance activities.
• When needed, clean the outer shell with a soft damp cloth. Use a mild detergent if
necessary. After cleaning, dry with a soft cloth. Ensure it is completely dry before
using again.
• Spot-clean the cloth cover only, being very gentle so as not to wear down or tear the
fabric.
• To avoid damaging the outer material of the unit, do not use alcohol, strong cleaning
agents, abrasive cleaning powders, or rough brushes to clean.
STORAGE
• Store the unit in a cool, dry location when not in use. To prevent dirt and dust
buildup, store in the original packaging that the unit came in.
• Do not store or use the product in a high-humidity environment, and do not store in
direct sunlight or excessively dusty environments. Humidity, heat, sunlight, and dust
can cause the mechanics to malfunction or deteriorate.
DISPOSAL
If you need to throw the unit away, please follow local rules and policies for properly
disposing of e-waste.
