Such unauthorized attempts to disassemble the device may also cause irreparable damage to the device and/or cause bodily harm.

[Power Precautions]

Insert the charger USB cable correctly and make sure it is firmly connected. 

Do not bend, pull, twist, heat, or cut the charging cable. Doing so may damage the cable and cause fire or electric shock.

Do not place any heavy materials on the charger.

When cleaning, it is advised to disconnect the cable, as there may be risks of fire or electric shock.

Avoid vibration or shock and disconnect the charger when not in use.

Do not use the charger if the USB connector is loose or damaged. If the connection is unstable, it may cause damage and/or ignite.

[High Temperature and Humidity Precaution]

Do not use the device in hot or humid places.

Do not place the device in direct sunlight or under a heater, quilt, or carpet for extended periods of time, or in a hot or humid environment such as a steam room or sauna.

Normal operating temperature: 0~40 degrees Celsius

[Chemical Precautions]

Do not use alcohol, benzene, acetone, or any other chemical-based solutions to clean the device. The device may malfunction or may cause fire. In addition, there may be irreparable damage done on the device.

To clean, gently wipe the device with a soft cloth.

If you need help with cleaning the device, please contact our customer support.

[Metal Precautions]

If metal objects are shorted to the charging terminal, there may be risk of explosion and/or irreparable damage to the device.

[Children/Pets Precaution]

Store the device, charger, and parts away from children and pets. 

The device may cause electric shock, or cause exposure to electromagnetic waves when damaged or in contact with saliva. 

Make sure that children and pets do not swallow the device. Swallowing or biting the device, charger, or parts may cause suffocation and/or bodily harm. 

Keep the device, charger, or parts away from sharp metal objects, such as keys, hairpins, coins, or nails. Any unintended pressure to the battery may compromise the quality and/or cause irreparable damage to the charger.

[Hazardous Area Precaution]

Do not use the device in magnet-sensitive atmospheres. The device may affect high-frequency equipment nearby. 

Do not place the device in an unstable place, such as a vibrating surface or a sloping area.

Failure to do so may damage the device and/or cause bodily harm.

[Fire Precaution]

Do not wrap the device or cover with insulation when in-use or when charging. 

Make sure to recycle it correctly. Disposing electronic devices in the trash may cause environmental damage.

If you need assistance with disposing the device, battery and/or the charger, please contact your local authorities.

[Skin Damage Precaution]

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.
