CERPASS TECHNOLOGY CORP. Report No.: SEFI1302096-A Radio frequency exposure LIMIT According to §15.247(i), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission's guidelines. See § 1.1307(b)(1) of this chapter. EUT Specification EUT SOUNDBAR SPEAKER WLAN: 2.412GHz ~ 2.462GHz Frequency band WLAN: 5.725GHz ~ 5.850GHz (Operating) Bluetooth: 2.402GHz ~ 2.480 GHz Portable (<20cm separation) Device category Mobile (>20cm separation) Occupational/Controlled exposure (S = 5mW/cm2) Exposure classification General Population/Uncontrolled exposure (S=1mW/cm2) Single antenna Multiple antennas Antenna diversity Tx diversity Rx diversity Tx/Rx diversity GFSK:-0.33dBm(0.927mW) Max. output power 8DPSK:-0.45dBm(0.902mW) Antenna gain (Max) 1.13 dBi (Numeric gain:1.297 ) MPE Evaluation* Evaluation applied SAR Evaluation N/A Remark: 1. The maximum output power is -0.33 dBm (0.927mW) at 2441 MHz (withnumeric 1.297 antenna gain.) 2. DTS device is not subject to routine RF evaluation; MPE estimate is used to justify the compliance. 3. For mobile or fixed location transmitters, no SAR consideration applied. The maximum power density is 1.0 mW/cm2 even if the calculation indicates that the power density would be larger.

CERPASS TECHNOLOGY CORP. Report No.: SEFI1302096-A TEST RESULTS No non-compliance noted. Calculation 30 × P × G E2 Given E= & S= d 3770 Where E = Field strength in Volts / meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power density in milliwatts / square centimeter Combining equations and re-arranging the terms to express the distance as a function of the remaining variables yields: 30 × P × G S= 3770d 2 Changing to units of mW and cm, using: P (mW) = P (W) / 1000 and d (cm) = d(m) / 100 Yields 30 × (P / 1000) × G P×G S= = 0.0796 × 2 Equation 1 3770 × (d / 100) 2 d Where d = Distance in cm P = Power in mW G = Numeric antenna gain S = Power density in mW / cm2 Cerpass Technology Corp.
