Precautions

High volume may adversely affect your hearing.

Do not use the unit while walking, driving, or cycling. Doing so may cause traffic accidents.

Do not use in hazardous areas unless the surrounding sound can be heard.

If the earbuds are not securely attached, they may fall off and remain inside the ear during use. Make sure that the earbuds are securely attached before use.

There is a danger that small parts may be swallowed. After use, store in a location out of reach of small children.

If the earbuds become dirty, remove them from the unit and gently wash them by hand using a neutral detergent. After cleaning, thoroughly wipe off any moisture.

Note about static electricity
If you use the unit when the air is dry, you may experience discomfort due to static electricity accumulated on your body. This is not a malfunction of the unit. You can reduce the effect by wearing clothes made of natural materials that do not easily generate static electricity.
