Radio-Wave Exposure and Specific Absorption Rate (SAR) Information
Radio Frequency (RF) Exposure and Specific Absorption Rate (SAR)
When the phone or Bluetooth handsfree is turned on, it emits low levels of radio frequency energy. International safety guidelines have been developed through periodic and thorough evaluation of scientific studies. These guidelines establish permitted levels of radio-wave exposure. The guidelines include a safety margin designed to assure the safety of all persons and to account for any variations in measurements.
Specific Absorption Rate (SAR) is used to measure radio frequency energy absorbed by the body when using a mobile phone. The SAR value is determined at the highest certified power level in laboratory conditions, but because the phone is designed to use the minimum power necessary to access the chosen network, the actual SAR level may be well below this value. There is no proof of differences in safety based on differences in SAR value.
Products with radio transmitters sold in the US must be certified by the Federal Communications Commission (FCC). When required, tests are performed with the phone placed at the ear and worn on the body. This phone has been tested and meets the FCC RF exposure guidelines for body-worn operation. Please use an accessory designated for the product or an accessory that contains no metal and that positions the handset a minimum of 1.0 cm from the body.

Important Information for Customers in the United States
THIS PHONE MODEL HAS BEEN CERTIFIED IN COMPLIANCE WITH THE GOVERNMENT'S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.
The XQ-ES44 mobile phone has been designed to comply with the applicable safety requirements for exposure to radio waves. Your wireless phone is a radio transmitter and receiver. It is designed to not exceed the limits* of exposure to radio frequency (RF) energy set by governmental authorities. These limits establish permitted levels of RF energy exposure for the general population. The guidelines are based on standards that were developed by international scientific organizations through periodic and thorough evaluation in scientific studies. The standards include a safety margin designed to assure the safety of all individuals, regardless of age or health. The radio-wave exposure guidelines employ a unit of measurement known as the Specific Absorption Rate (SAR). Tests for SAR are conducted using standardized methods 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 phone models, they are all designed to meet the relevant guidelines for exposure to radio waves.
The highest SAR values as reported to the authorities for this phone model were 0.85 W/kg* when tested for use by the ear, 0.67 W/kg* when worn on the body, and 0.69 W/kg in the Wi-Fi hotspot mode. For body-worn operation, the phone has been tested when positioned a minimum of 10 mm from the body without any metal parts in the vicinity of the phone or when properly used with an appropriate accessory and worn on the body.
For devices that include "Wi-Fi hotspot" functionality, SAR measurements for the device operating in the Wi-Fi hotspot mode were taken using a separation distance of 10 mm.
Use of third-party accessories may result in different SAR levels than those reported.
** Before a phone model is available for sale to the public in the US, it must be tested and certified by the Federal Communications Commission (FCC) that it does not exceed the limit established by the government-adopted requirement for safe exposure*. The tests are performed in positions and locations (i.e., by the ear and worn on the body) as required by the FCC for each model. The FCC has granted an Equipment Authorization for this phone model with all reported SAR levels evaluated as in compliance with the FCC RF exposure guidelines. While there may be differences between the SAR levels of various phones, all mobile phones granted an FCC equipment authorization meet the government requirement for safe exposure. SAR information on this phone model is on file at the FCC and can be found under the Display Grant section of https://www.fcc.gov/oet/ea/fccid after searching on FCC ID PY7-73716J. Additional SAR-related information can also be found on the Mobile and Wireless Forum at https://www.mwfai.org/.
* In the United States, the SAR limit for mobile phones used by the public is 1.6 watts/kilogram (W/kg) averaged over one gram of tissue. The standard incorporates a margin of safety to give additional protection for the public and to account for any variations in measurements.
