Moto G 系列 – SAR

手機廠商一向都有公佈每部手機所發出既輻射量數據, Specific Absorption Rates 簡稱 SAR, 不過近年各廠商只在說明書內簡單說明輻射量數據 (SAR) 已測試低於安全標準, 往往不列出實際輻射量數據為何. 小棗在 Motorola 網頁終於找到 Moto G 既輻射量數據. 不過, 這個 SAR 數值會否只代表單 sim card 版本就不得而知, 始終香港版本 Moto G 為雙卡手機, 理論上 SAR 數值相對單 sim card 版為高.

THE SELECTED PRODUCT Moto G - XT1032 MEETS THE GOVERNMENT'S REQUIREMENTS FOR EXPOSURE TO RADIO WAVES.

Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. Government and by Health Canada for Canada. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age or health.

The exposure standard for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate, or SAR. The SAR limit set by the FCC and by Health Canada is 1.6W/kg.* Tests for SAR are conducted using standard operating positions accepted by the FCC and by Industry Canada with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station, the lower the power output.

Before a phone model is available for sale to the public in the U.S. and Canada, it must be tested and certified to the FCC and Industry Canada that it does not exceed the limit established by each government for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) reported to the FCC and available for review by Industry Canada. The highest SAR value for this model phone when tested for use at the ear is 1.17 W/kg** and when worn on the body, as described in this user guide, is 1.06 W/kg.** While there may be differences between the SAR levels of various phones and at various positions, they all meet the governmental requirements for safe exposure.

Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) web-site at http://www.phonefacts.net or the Canadian Wireless Telecommunications Association (CWTA) website, http://www.cwta.ca.
