 SAR: This mobile phone meets government requirements for exposure to radio
waves. Your mobile phone is a radio transmitter and receiver. It is designed and
manufactured not to exceed limits for exposure to radio frequency (RF) energy.
These limits are part of comprehensive guidelines and establish permitted levels of
RF energy for the population. The guidelines were developed and confirmed by
independent scientific organizations through periodic and thorough evaluation of
scientific studies. The limits include a substantial safety margin designed to assure
the safety of all persons, regardless of age and health. The exposure standard for
mobile phones employs a unit of measurement known as the Specific Absorption
Rate, or SAR. The highest tested SAR values for this mobile phone compliance
against FCC standard limit 1.6 W/kg is 0.302 W/kg for body (based on 1.5 cm
distance separation from body to the device) and 0.600 W/kg for head (while the
phone touches ear).
 Do not touch the antenna area when the phone is in use. Touching the antenna
area affects call quality and may cause the phone to operate at a high power level
than needed.

4
 Some people may be susceptible to epileptic seizures or blackouts when exposed
to flashing lights, such as when watching television or playing video games. If you
have experienced seizures or blackouts, or if you have a family history of such
occurrences, please consult with you doctor before playing video games on you
phone or enabling a flashing-lights feature on your phone. (The flashing-light
feature is not available on all products.)

9
 Do not store battery in hot areas or throw it into fire. Otherwise, it will cause
explosion.
 Do not disassemble or refit the battery. Otherwise, it will cause liquid leakage,
overheating, explosion and ignition of the battery.
 Please store the battery in a cool dry place if you don’t use it for a long period.
 The battery can be recharged for hundreds of times, but it will eventually wear out.
When the operating time (talk time and standby time) is noticeably shorter than
normal, it is time to replace a new one.
 Please stop using the charger and battery when they are damaged or show
evidence of aging.
 Return the wear-out battery to the provider or dispose of it in accordance with
environment regulations. Do not dispose of it in household rubbish.
