understanding exposure to radio frequency (RF)
energy
The Rio II is a low-power radio transmitter and receiver. When the phone is on, it
intermittently receives and transmits radio frequency (RF) energy (radio waves).
That energy level varies in order to achieve optimum performance – so it’s higher
in areas with poor reception and lower in areas with good reception.
Your phone is designed to comply with safety requirements for exposure to radio
waves. These requirements are based on scientific guidelines that include safety
margins designed to assure the safety of all persons, regardless of age and health.
The guidelines employ a unit of measurement known as the Specific Absorption Rate,
or SAR. Tests for SAR are conducted using a standardised method with the
phone transmitting at its highest certified power level in all used frequency bands.
While there may be differences between the SAR levels of various network operator
phone models, they are all designed to meet the relevant guidelines for exposure
to radio waves.
The SAR limit recommended by the International Commission on Non-Ionizing
Radiation Protection (ICNIRP) is 2.0 W/kg averaged over ten (10) grams of tissue.
The highest SAR value for this model phone tested for use at the ear is
1.4 W/kg (10g).
