When using the device for a long tine, the temperature of the surface of the device may rise. It is not unusual for the device to do this, and the device should still operate properly. Stop using the device immediately if it causes skin spots, pigmentation, or burns.

If the device causes any allergic reaction, stop using the device immediately and consult a doctor.

Stop using the device if the top cover is damaged to expose any of the inner mechanical parts of the device.

[Magnetism Precaution]

Do not make close contact with objects with underlying magnetic chips, such as credit cards, phone cards, bankbooks, and tickets. Information may be damaged due to the device's magnetic property. 

Do not use the magnetic charging cradle with any other object, as it contains a strong magnet that may interfere with pacemakers, credit cards, watches, and other magnet-sensitive objects. 

[Storage Precaution]

When not in use, disconnect the charging cable from the outlet and store it in a safe place.

[Battery Precaution]

In hot or humid places, the battery may not charge well or may be consumed more quickly than average.

If you want to use the device again after leaving it unused for a prolonged period, use it after the device is fully charged.

Removing the battery by force may cause it to ignite or explode.

Do not expose the battery or charger to direct sunlight or use it in a place with high humidity, such as a sauna or a heated automobile.

Do not open, disassemble, damage, bend, deform, puncture, or crush the device.

Do not attempt to alter or modify the battery, insert foreign objects, immerse or expose to water or other liquids.

Once the device is fully charged, disconnect the charger from the outlet to prevent unnecessary power consumption.
