1 Warnings and Precautions
To use HUAWEI ETS2251 Fixed Wireless Terminal (FWT) accurately,
efficiently and securely, you should notice following cautions.
Basic Cautions
1Check fittings based on the packing list to make sure they are complete and
undamaged.
2Read this manual carefully before installing and using FWT.
Electronic Device
Switch your FWT off near high-precision electronic 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 wave
affects the operation of this 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).
ySwitch your FWT off 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 your FWT off
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 leave your FWT, battery, or power adapter in a high-temperature place
or use them in a place with flammable gas. Otherwise, malfunction of the
products, fire, or explosion may result.
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.
yBecause FWT contains precision devices, you should put it in a dry place and
away from moist materials.
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, overheat, 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.
yWhen lightning, if you use the power adapter, please turn off the FWT and
disconnect the power adapter from external power supply.

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.
Emergency Call
You can use your FWT for emergency calls. However, connections in all
conditions cannot be guaranteed. You should never rely solely on the FWT for
essential communications.
Battery
yIf the battery fluid gets into eyes, do not rub them. Wash with clean water and
seek medical assistance immediately.
yIf the battery fluid contacts skin or cloth, wash with clean water immediately to
avoid irritation to the skin.
yDo not dispose of the battery in fire. Otherwise, the battery may ignite or
explode.
yWhen installing the battery on your FWT, do not push the battery by force lest
battery fluid leak out or the battery crack.
yDo not connect two poles of the battery with metallic materials such as cables.

yRemove the dust on the power plug regularly.
yDo not use worn-out power cords. Otherwise, electric shock, short-circuiting of
the power adapter, or fire may result.
yDo not put the power adapter near the container filled with liquid such as water.
If the liquid comes into the power adapter, electrical leakage or other faults
may result.
yIf the liquid such as water comes into the power adapter accidentally, remove
the plug of the power adapter from the socket immediately.
yDisconnect the power adapter from the socket before cleaning or maintaining it.
Otherwise, electric shock or short-circuiting of the battery or power adapter
may result.
