Exposure to radio frequency energy
Radio wave exposure and Specific Absorption Rate (SAR)
information
This mobile phone model C3400 has been designed to comply with
applicable safety requirement for exposure to radio waves. This
requirement is based on scientific guidelines that include safety
margins designed to assure this 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 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 LG 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), which is 2W/kg
averaged over ten (10) gram of tissue.
• The highest SAR value for this model phone tested by DASY4
for use at the ear is 1.12 W/kg (10g).
• SAR data information for residents in countries/regions that have
adopted the SAR limit recommended by the Institute of Electrical
and Electronics Engineers (IEEE), which is 1.6 W/kg averaged
over one (1) gram of tissue.
