health and safety
SAR certification information
The device meets international guidelines for exposure to radio waves.
Your phone is a radio transmitter and receiver. It‟s designed not to exceed the limits
for exposure to radio waves recommended by international guidelines. The guidelines
were developed by ICNIRP, an independent technical standards body, and include
margins designed to assure the protection of all persons, regardless of age and
health.
These guidelines use a unit of measurement known as Specific Absorption Rate,
(SAR). The SAR limit for mobile devices is 1.6 W/kg and the highest SAR value for
this device when tested was1…

As SAR is measured when the phone is on its highest transmitting power, the actual
SAR of this device while operating normally is typically below the levels shown above.
This is because your phone automatically changes its power level to ensure it only
uses the minimum level required to reach the network.
The World Health Organization has stated that present scientific information does not
indicate the need for any special precautions for the use of mobile devices.
1. The tests are carried out in accordance with IEEE standard P1528-2003.

important safety information
For your own health and safety, please follow the radio frequency (RF) radiation
exposure guidelines and keep your phone no less than 1.5cm away from your body.
Failure to do this could mean that your RF exposure exceeds the guideline limits.
how to limit your radio frequency (RF) exposure
The World Health Organization (WHO) gives the following advice to people who want
to limit their exposure to RF radiation…
Present scientific information does not indicate the need for any special precautions
for the use of mobile phones. If individuals are concerned, they may choose to limit
their own or their children‟s RF exposure by limiting the length of calls, or using
„hands-free‟ devices to keep mobile phones away from the head and body.
Further information on the subject can be obtained from the World Health
Organization website at http://www.who.int/peh-emf WHO Fact sheet 193: June 2000.
