Radio Frequency (Rf) Energy - Zte 840Z User Manual

1.8 Radio Frequency (RF) Energy

Your handset is a low-power radio transmitter and receiver. When powered on, it intermittently
receives and transmits radio frequency (RF) energy (radio waves). The transmit power level is
optimized for the best performance, and automatically reduces in the areas with better
reception.
Exposure to radio frequency energy
Radio wave exposure and Specific Absorption Rate (SAR) information:
• The handset is designed to comply with safely, requirements for exposure to radio waves.
This requirement is based on scientific guidelines that include safety margins designed to
assure the safety of all persons, regardless of age and health.
• The radio wave exposure guidelines employ a unit of measurement known as the Specific
Absorption Rate, or SAR. Tests for SAR are conducted using a standardized 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 ZTE 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 2W/kg averaged over ten (10) grams of tissue.
• The highest SAR value for this model phone tested for use at the ear is 0.911 W/kg (10g).
