Electronic device
Do not use your device if using the device is prohibited. Do not use the device if doing so causes danger
or interference with other electronic devices.
Interference with medical equipment
• Follow rules and regulations set forth by hospitals and health care facilities. Do not use your device
where prohibited.
• Some wireless devices may affect the performance of hearing aids or pacemakers. Consult your
service provider for more information.
• Pacemaker manufacturers recommend that a minimum distance of 15 cm be maintained between a
device and a pacemaker to prevent potential interference with the pacemaker. If using a pacemaker,
hold the device on the side opposite the pacemaker and do not carry the device in your front pocket.
Areas with flammables and explosives
• Do not use the device where flammables or explosives are stored (in a gas station, oil depot, or
chemical plant, for example). Using your device in these environments increases the risk of explosion
or fire. In addition, follow the instructions indicated in text or symbols.
• Do not store or transport the device in containers with flammable liquids, gases, or explosives.
Operating environment
• Avoid dusty, damp, or dirty environments. Avoid magnetic fields. Using the device in these
environments may result in circuit malfunctions.
• Before connecting and disconnecting cables, stop using the device and disconnect it from the power
supply. Ensure that your hands are dry during operation.
• Place the device on a stable surface.
• Keep the device away from electronic appliances that generate strong magnetic or electric fields,
such as a microwave oven or refrigerator.
• During thunderstorms, power off your device and remove all cables connected to it to protect against
lightning strikes.
• Do not use your device during thunderstorms to protect your device against any danger caused by
lightning.
• Ideal operating temperatures are 0 °C to 40 °C. Ideal storage temperatures are -20 °C to +70 °C.
Extreme heat or cold may damage your device or accessories.
• Keep the device and accessories in a well-ventilated and cool area away from direct sunlight. Do not
enclose or cover your device with towels or other objects. Do not place the device in a container with
poor heat dissipation, such as a box or bag.
• To protect your device or accessories from fire or electrical shock hazards, avoid rain and moisture.
• Keep the device away from sources of heat and fire, such as a heater, microwave oven, stove, water
heater, radiator, or candle.

liquid enters the device, immediately stop using it, power it off, and remove all cables connected to it.
Then, contact a Huawei authorized service center.
• Do not block device openings. Reserve a minimum of 10 cm around the device to dissipate heat.
• Stop using your device or applications for a while if the device is overheated. If skin is exposed to an
overheated device for an extended period, low temperature burn symptoms, such as red spots and
darker pigmentation, may occur.
