Prevention of Hearing Damage

Using a headset at high volume can damage your hearing. To reduce the risk of

damage to hearing, lower the headset volume to a safe and comfortable level.

Safety of Children

Comply with all precautions with regard to children's safety. Letting the child play with

your device or its accessories, which may include parts that can be detached from the

device, may be dangerous, as it may present a choking hazard. Ensure that small

children are kept away from the device and accessories.

Accessories

Choose only batteries, chargers, and accessories approved for use with this model by

the device manufacturer. The use of any other type of battery, charger, or accessory

may invalidate any warranty for the device, may be in violation of local rules or laws,

and may be dangerous. Please contact your dealer for information about the

availability of approved batteries, chargers, and accessories in your area.

Battery and Charger

• Unplug the charger from the electrical plug and the device when not in use.

• The battery can be charged and discharged hundreds of times before it eventually

wears out. When the standby time and the talk time are shorter than the normal

time, replace the battery.

• Use the AC power supply defined in the specifications of the charger. An improper

power voltage may cause a fire or a malfunction of the charger.

• Do not connect two poles of the battery with conductors, such as metal materials,

keys, or jewelries. Otherwise, the battery may be short-circuited and may cause

injuries and burns on your body.

• If battery electrolyte leaks out, ensure that the electrolyte does not touch your skin

and eyes. When the electrolyte touches your skin or splashes into your eyes, wash

your eyes with clean water immediately and consult a doctor.

• If there is a case of battery deformation, color change, or abnormal heating while

you charge or store the battery, remove the battery immediately and stop using it.

Otherwise, it may lead to battery leakage, overheating, explosion, or fire.
