SAR Certification information (Specific Absorption Rate)
The device is compliant to European Union (EU) standards that
limit human exposure to radio frequency (RF) energy emitted
by radio and telecommunications equipment. These standards
prohibit the sale of mobile devices that exceed a maximum
exposure level (known as SAR) of 2.0 W/kg.
During testing, the maximum SAR recorded for this model
was equal to 0.737 W / kg. During normal use, the actual SAR
level can be much lower, as the device has been designed to
emit only the RF energy necessary to transmit a signal to the
nearest base station. By automatically emitting lower levels
when possible, your device reduces your overall exposure to
RF energy.
To avoid damage to your hearing, please do not
listen at high volume for a long time.
