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.

Operating Environment


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.

Do not put your 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.

Because 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.

Place the FWT in a dry place. Do not put a towel over the FWT, or put it in a box or suitcase while
using.

Because FWT contains precision devices, you should put it in a dry place and away from moist
materials.

Before cleaning FWT, please turn off the FWT, and then disconnect the power supply and take off
the battery. Before moving FWT, please disconnect the external power supply.

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.

Do 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.

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.
