•
Do not disassemble or open, crush, bend or deform, puncture or shred the battery. Otherwise, it may lead
to electrolyte leakage, overheating, fire, or explosion.
•
Do not solder battery poles or dismantle the battery. Doing so may lead to electrolyte leakage, excessive heat,
fire, or explosion.
Cleaning and maintenance
•
Keep the device and accessories dry. Do not attempt to dry it with an external heat source, such as a
microwave oven or hair dryer.
•
Do not expose your device or accessories to extreme heat or cold. These environments may interfere with
proper function and may lead to fire or explosion.

The device and its accessories (if included), such as the power adapter, headset, and battery should not be
disposed of with household garbage.
•
Disposal of the device and its accessories is subject to local regulations. Support proper collection and recycling.
FCC Regulatory Compliance
Body worn operation
The device complies with RF specifications when used near your ear or at a distance of 1.5 cm from your
body. Ensure that the device accessories, such as a device case and device holster, are not composed of metal
components. Keep the device away from your body to meet the distance requirement.
Certification information (SAR)
This device is also designed to meet the requirements for exposure to radio waves established by the Federal
Communications Commission (USA).
The SAR limit adopted by the USA is 1.6 W/kg averaged over one gram of tissue. The highest SAR value reported
to the FCC for this device type complies with this limit. The highest SAR value reported to the FCC for this device
type when using at the ear is 0.790 W/kg, and when properly worn on the body is 1.008 W/kg.
FCC statement
FCC ID: QISH891L
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
Caution: Any changes or modifications to this device not expressly approved by Huawei Technologies Co., Ltd.
for compliance could void the user's authority to operate the equipment.
Hearing Aid Compatibility (HAC) regulations for mobile phones
In 2003, the FCC adopted rules to make digital wireless telephones compatible with hearing aids and cochlear
implants. Although analog wireless phones do not usually cause interference with hearing aids or cochlear
implants, digital wireless phones sometimes do because of electromagnetic energy emitted by the phone's
antenna, backlight, or other components.
Your phone is compliant with FCC HAC regulations (ANSI C63.19).
While some wireless phones are used near some hearing devices (hearing aids and cochlear implants), users
may detect a buzzing, humming, or whining noise. Some hearing devices are more immune than others to this
interference noise, and phones also vary in the amount of interference they generate.
The wireless telephone industry has developed a rating system for wireless phones, to assist hearing device
users find phones that may be compatible with their hearing devices.
Not all phones have been rated. Phones that are rated have the rating on their box or a label located on the box.
The ratings are not guarantees.
Results will vary depending on the user's hearing device and hearing loss. If your hearing device happens to be
vulnerable to interference, you may not be able to use a rated phone successfully. Trying out the phone with your
hearing device is the best way to evaluate it for your personal needs.
