RF Exposure Information/Specific Absorption Rate (SAR) Information
RF Exposure Information/Specific Absorption Rate* (SAR) Information
WX04SH meets the MIC's**** technical regulation for exposure to radio waves.
The technical regulation* established permitted levels of radio frequency energy, based on standards developed by independent scientific organizations through periodic and thorough evaluation of scientific studies.
The regulation employs a unit of measurement known as the Specific Absorption Rate, or SAR.
The SAR limit is 2 watts/kilogram (W/kg)** averaged over ten grams of tissue.
The limit includes a substantial safety margin designed to assure the safety of all persons, regardless of age and health.
The value of the limit is equal to the international guidelines recommended by ICNIRP*****.
The highest SAR values for WX04SH are 0.036 W/kg (over PHS network) and 0.357 W/kg (over 3G network) when tested for use at the ear.
While there may be differences between the SAR levels of various phones and at various positions, all phones meet MIC's technical regulation.
Although the SAR is determined at the highest certified power level, the actual SAR of handset during operation can be well below the maximum value.
Use at positions other than at the ear
Handset may be used at positions other than at the ear. By using an accessory such as a belt clip holster that maintains a 1.5 cm separation with no metal (parts) between the body and handset, handset will comply with international guidelines for radio wave protection (***).
The World Health Organization has announced that "A large number of studies have been performed over the last two decades to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use."

*The technical regulation is provided in Article 14-2 of the Ministry Ordinance Regulating Radio Equipment.
**Provided for in "Radio-radiation protection guidelines," reported in 1997 by the Telecommunications Technology Council, Ministry of Posts and Telecommunications.
***A method of measuring SAR when a mobile phone is used at positions other than at the ear was established in March 2010 through an international standard (IEC62209-2). MIC technical regulation was reported in October 2011 by the Information and Communications Council.
