2. RF Exposure Evaluation 2.1. Product Category for RF Exposure
Product Category for using: Portable. Note: The Bluetooth part is in the controller which is operated by hand, so we categorize this product to be portable product for RF exposure. The distance from the wireless part to the body is <5mm. 2.2. Limits According to KDB 447498 D01 General RF Exposure Guidance v06 For 100 MHz to 6 GHz and test separation distances  50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [f(GHz)]  3.0 for 1-g SAR, and  7.5 for 10-g extremity SAR, where  f(GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation
 The result is rounded to one decimal place for comparison

2.3. Test Procedure
Software provided by client enabled the EUT to transmit and receive data at lowest, middle and highest channel individually. The temperature and related humidity: 24 and 53RH.

For the worst: the RF power: [2480 MHz, -10.863 dBm, 0.0820 mW) output power] (0.0820/5) ·[2.480(GHz)] = 0.0258 < 3.0 for 1-g SAR
Then SAR evaluation is not required.
