Table of Contents

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 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.

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 architecture and

security design of FWT. You must bear any consequence resulted from the

operation without permission.

Your 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.

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.

Do not connect two poles of the battery with metallic materials such as cables.
