1 Warnings and Precautions
Before using HUAWEI Fixed Wireless Terminal (hereinafter
referred to as FWT), read the following cautions and let your
children know these, so that you can use your FWT correctly
and safely.
Basic Cautions
According to the packing list, check items in the package box to
make sure that they are complete and undamaged.
Before installing and using FWT, read the user manual carefully.
Electronic Device
Switch off your FWT near high-precision electronic devices
such as hearing aids, pacemakers, fire alarm systems,
automatic gates, and other automatic-control devices. The FWT
may affect the performance of these devices.
Such devices include hearing aids, pacemakers, fire alarm
systems, automatic gates, and other automatic-control devices.
If you are using an electronic medical device, consult the device
manufacturer and confirm whether the radio waves affect the
operation of the electronic device.
Hospital
Pay attention to the following points in hospitals or health care
facilities:
yDo not take your FWT into the operating room (OR), intensive
care unit (ICU), or coronary care unit (CCU).

2
ySwitch off your FWT near medial devices.
yObserve any instructions wherever the use of wireless device
is prohibited.
Traffic Safety
yDo not use your FWT while driving. Secure the FWT on its
holder. Do not place the FWT on the seat or other places
where it can get loose in a sudden stop or collision.
yObserve the rules and regulations of airline companies.
Switch off your FWT before boarding an aircraft.
Operating Environment
yDo not place magnetic storage media such as magnetic cards
and floppy disks near the FWT. Radiation from the FWT may
erase the information stored on them.
yDo not put your FWT, battery, or other accessories in
containers with strong magnetic field, such as the induction
cooker and microwave oven. Otherwise, circuit failure, fire, or
explosion may result.
yDo not place or use the FWT, the battery or the power adapter
near any heat sources such as fire or a heater; or places with
flammable gases; or areas with electrical appliances that give
out heat. Otherwise, it will cause fire, explosion and
breakdown of the FWT
yBecause FWT needs to eliminate heat during working, put the
FWT and the power supply in a ventilated and shadowy place.
Never airproof the FWT or put something on it or place it near
water, fire as well as inflammable and explosive materials.
yPlace the FWT in a dry place. Do not put a towel over the
FWT, or put it in a box or a suitcase while using.
yBecause FWT contains precision devices, you should put it in
a dry place and away from moist materials.

3
yBefore cleaning FWT, please turn off the FWT, and then
disconnect the power supply and take out the battery. Before
moving FWT, please disconnect the external power supply.
yDo not subject your FWT, battery, and power adapter to
serious collision or shock. Otherwise, battery leakage, FWT
malfunction, overheats, fire, or explosion may result.
yDo not place sharp metal objects such as pins near the
earpiece. The earpiece may attract these objects and hurt you
when you are using the FWT.
yDo not place the FWT in the area over the air bag or in the air
bag deployment area. Otherwise, the FWT may hurt you
owing to the strong force when the air bag inflates.
yPut your FWT, battery, and power adapter in places beyond
the reach of children. Do not allow children to use the FWT,
battery, or power adapter without guidance.
yDo not touch the antenna when a call is going on. Touching
the antenna may affect call quality and cause the FWT to
operate at a power level higher than needed.
yThe network signal condition will directly affect the quality and
stability of the call. Consequently, you should place FWT in a
place where it can receive network signal well. Do not put
FWT in a building with an iron or metal roof. The distance
between FWT and other metal materials (such as metal
brackets or metal doors and windows) should be greater than
25cm and the distance between FWTs should be greater than
30cm.
yDo not open the chassis in any case and the device should be
maintained by a qualified maintenance department.
yWithout permission, you are not allowed to modify the
architecture and security design of FWT. You must bear any
consequence resulted from the operation without permission
yYour FWT is designed to conform to the authoritative
international radio frequency (RF) specifications. Use FWT
accessories approved by Huawei only.

4
