Operational Description 1. The SH52 Bluetooth headset based on CSR BC57F687A05 chipset, It is compliant to Bluetooth v2.1 + EDR specification. It works with a crystal Y1 (26MHz) References to the document schematic U101_BC57F687A05 is a single chip Radio and baseband IC for Bluetooth 2.4GHZ systems. it provides Bluetooth RF, baseband and some power regulator functions. It is integrated DC +1.8V and +1.5V power supply. U1 ATS2301is a MP3 MCU IC Y2 is a crystal oscillator, provides 32.768kHz clock reference. The headset has Blue, Yellow and Red indicator lights to show different working state, and has paly,Phone, Volume up, Volume Down buttons to operation the headset. 2．The Signal Path description When the headset connects to a mobile phone, the built-in MCU will control the RF modem to process the baseband signal, indicate the working state by the LED. There are Multi-function Button, Volume up button and Volume Down button for you to increase the volume or decrease the volume of the speaker.

RF Exposure Requirements Product Description: Bluetooth Headset Model No.: SH52 FCC ID: SF4-SH52 Acorrding to the KDB-447498, the following RF exposure evaluation shall to demonstrate RF exposure compliance. Tx frequency range: 2402~2480MHz Device category: Portable device Maximum Conducted Output Power: 3.4041 mW (5.320 dBm) Maximum Antenna Gain: 0 dBi Maximum EIRP Output Power: 3.4041 mW (5.320 dBm) Limit: 10mW Source-based time-averaged EIRP output power is 3.4041 mW < 10mW So the transmitter complies with the RF exposure requirements and the SAR is not required.
