Operation and safety
•
To prevent possible hearing damage, do not listen at high volume levels for long periods.
• Ideal temperatures: 0 °C to 35 °C for operating, -20 °C to +55 °C for storage.
• Keep the device and the battery away from excessive heat and direct sunlight. Do not place them on or in heating
devices, such as microwave ovens, stoves, or radiators. Do not disassemble, modify, throw, or squeeze it. Do not
insert foreign objects into it, submerge it in liquids, or expose it to external force or pressure, as this may cause it to
leak, overheat, catch fire, or even explode.
• Do not attempt to replace the battery yourself — you may damage the battery, which could cause overheating, fire,
and injury. The built-in battery in your device should be serviced by Huawei or an authorised service provider.
• The power plug is used as the disconnect device. For pluggable equipment, the socket-outlet shall be easily
accessible.
• Adult supervision is advised if children are to use or come into contact with this product.
• Please consult your doctor and the device manufacturer to determine if operation of your device may interfere with
the operation of your medical device.
