• For traffic safety, do not use earphones while driving or cycling.
• This product is capable of producing loud noises which may damage your hearing.

It is recommended to place the product at a safe distance from your ear.

Exposure to Radio Waves

• Your mobile is designed not to exceed the limits for exposure to radio waves (radio

frequency electromagnetic fields) recommended by international guidelines.

• The guidelines were developed by an independent scientific organization (ICNIRP)

and include a substantial safety margin designed to assure the safety of all

persons, regardless of age and health.

• The radio wave exposure guidelines use a unit of measurement known as the

Specific Absorption Rate, or SAR. The SAR limit for mobile devices is 2.0 W/kg.

• Tests for SAR are conducted using standard operating positions with the device

transmitting at its highest certified power level in all tested frequency bands. The

highest SAR values under the ICNIRP guidelines for this device model are:

• Body SAR : 0.079 W/Kg (10g)
• During use, the actual SAR values for this device are usually well below the values

stated above. This is because, for purposes of system efficiency and to minimize

interference on the network, the operating power of your mobile device is

automatically decreased when full power is not needed for the call. The lower the

power output of the device, the lower its SAR value.

Built-in Battery Care

• Your product is powered by a built-in rechargeable battery.
• The battery can be charged and discharged hundreds of times, but will eventually

wear out.

• Unplug the charger from the electrical plug and the product when not in use.
• Do not leave a fully charged battery connected to a charger, since overcharging

may shorten its lifetime.

• If left unused, a fully charged battery will lose its charge over time.
• Leaving the product in hot or cold places, such as in a closed car in the summer

and winter conditions, will reduce the capacity and lifetime of the battery.

• Always try to keep your device in a cool, moisture-free environment that’s less

than 32°C. A product with a hot or cold battery may not work temporarily, even

when the battery is fully charged. Battery performance is particularly limited in

temperatures well below freezing.

• If you plan to store your device for longer than six months, charge the battery for

an hour every six months to keep it fresh.

• The unit should be fully recharged after using the device each time. This will keep

the health of the battery.

• Do not continue to operate the unit if you are in any doubt about it working

normally, or if it is damaged in any way - switch off, unplug from the mains socket

and consult your dealer.

Wireless Devices

• Wireless devices can transmit radio frequency (RF) energy, whenever batteries are

installed and the wireless device is turned on (If it has an On/Off switch).

Temperature

• Avoid extreme degrees of temperature, either hot or cold. Place the unit well away

from heat sources such as radiators or gas / electric fires.

• Avoid exposure to direct sunlight and other sources of heat.

Naked Flames

• Never place any type of candle or naked flame on the top of or near the unit.

Interference

• Do not place the unit on or near appliances which may cause electromagnetic

interference. If you do, it may adversely affect the working performance of the unit,

and cause a distorted sound.

Audio Safety

•

Listening to loud sounds for prolonged periods of time may permanently

damage your hearing.

• Before putting on earphones, turn the volume down then put the earphones on

and slowly increase the volume until you reach a comfortable listening level.
