• Do not subject your FWT, battery, and power adapter to seri-
ous collision or shock. Otherwise, battery leakage, FWT
malfunction, overheats, fire, or explosion may result.
• Do not place sharp metal objects such as pins near the ear-
piece. The earpiece may attract these objects and hurt you
when you are using the FWT.
• Do 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.
• In raining and lightning, disconnect the power adapter from
external power supply and power off the FWT, In this case, if
the outdoor antenna is used, do not touch the FWT and
antenna.
• Put 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.
• Do 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.
• The network signal condition will directly affect the quality
and stability of the call. Consequently, you should place the
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 dis-
tance 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.
• Do not open the chassis in any case and the device should
be maintained by a qualified maintenance department.
• Without permission, you are not allowed to modify the archi-
tecture and security design of FWT. You must bear any con-
sequence resulted from the operation without permission.
•
Your FWT is designed to conform to the authoritative inter-
national radio frequency (RF) specifications. Use FWT
accessories approved by Huawei only.
•
The antenna(s) used for this transmitter must be installed to
provide a separation distance of at least 20cm from all per-
sons.
Emergency Call
You can use your FWT for emergency calls. However, connec-
tions in all conditions cannot be guaranteed. You should never
rely solely on the FWT for essential communications.
Battery
• If the battery fluid gets into eyes, do not rub them. Wash with
clean water and seek medical assistance immediately.
• If the battery fluid contacts skin or cloth, wash with clean
water immediately to avoid irritation to the skin.
• Do not dispose of the battery in fire. Otherwise, the battery
may ignite or explode.
• When installing the battery on your FWT, do not push the
battery by force lest battery fluid leak out or the battery
crack.

als such as cables.
