Introduction The Sony Ericsson SAR Laboratory has performed measurements of the maximum potential exposure to the user of portable cellular phone FCC ID PY7AC052013 model Z525i. This phone is identical to FCC ID PY7AC052011 model Z520i (Hardware Version B) with added push-to-talk (PTT) functionality that is enabled in GSM Mode with 1/8 duty cycle. The Specific Absorption Rate (SAR) of this product was measured. The applicable RF safety guidelines and the SAR measurement specifications used for the test are described in [1]. 2.
