Operating Environment
y
Do 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.
y
Do 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.
y
Do not place or use the FWT, battery or 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
y
Because the FWT eliminates 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.
y
Place the FWT in a dry place. When using it, do not put a towel over the FWT, or put it
in a box or a suitcase.
y
Because the FWT contains precision devices, you should put it in a dry place and away
from moist materials.
y
Before cleaning the FWT, turn off the FWT. Then disconnect the power supply and take
out the battery. Before moving the FWT, disconnect the external power supply.
y
Do not subject your FWT, battery, and power adapter to serious collision or shock.
Otherwise, battery leakage, FWT malfunction, overheats, fire, or explosion may result.
y
Do not place sharp metal objects such as pins near the earpiece. The earpiece may attract
these objects and hurt you when you use the FWT.
y
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.
y
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.
y
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.
y
The network signal condition will directly affect the quality and stability of a call.
Consequently, you should place the FWT in a place where it can receive network signals
well. Do not put the FWT in a building with an iron or metal roof. The distance between
the FWT and other metal materials (such as metal brackets or metal doors and windows)
should be greater than 25 cm and the distance between FWTs should be greater than 30
cm.
y
Do not open the chassis in any case and the device should be maintained by a qualified
maintenance department.
y
Without permission, you are not allowed to modify the architecture and security design
of the FWT. Otherwise, you bear any consequence resulted from the operation without
permission.
y
Your FWT is designed to conform to the authoritative international Radio Frequency (RF)
specifications. Use FWT accessories approved by Huawei only.
y
The antenna(s) used for this transmitter must be installed with providing a separation
distance of at least 20 cm from all persons.
y
Warning: Do not go closer that 20 cm to the device while in operation
