5473A Clouds Rest Road : Mariposa, CA 95338 : Phone 209-966-5420 : Fax 209-742-6133 Maximum Permissible Exposure Calculations Date of Report: 7/2/04 Calculations prepared for: Calculations prepared by: John Kim Eddie Wong AnyData.net Incorporated 110 N. Olinda Place 18902 Bardeen Rd Brea, CA 9283 Irvine, CA 92612 Model Number: EMIV- Dual FCC Identification: NA Fundamental Operating Frequency: 824.04- 848.97, 1851.25-1908.75 MHz Maximum Rated Output Power: +25.5 dBm (0.3548Watt) Conducted Measured Output Power: 836.52 MHz +26.1 dBm (0.4074Watt) EIRP Measured Output Power: 1880.00 MHz +28.3 dBm (0.6792Watt) EIRP MPE Limit in accordance with 1.1310(b): Limits for general population/uncontrolled exposure MPE Limit for 824.25-848.97 MHz = f /1500 mW/cm2 = 1.25 mW/cm2 ( 12.5W/m2 ) MPE Limit for 1851.25-1908.75 MHz = 1 mW/cm2 (10 W/m2 ) Power Output Power Density Minimum (Watts) Limit Distance (mW/cm2) (Meters) 0.6792 1 0.0532m 0.4074 1.25 0.0509m 30 x Pt x G Power Density (W/m 2 ) = d 2 x Z0 Pt = Power Delivered to the Antenna G = Antenna Gain d = Distance in meters Zo = Impedance of Free Space The typical antennas to be used with the EUT are structure mount antenna which under normal operation has an antenna height of at least 0.2 meters (20 cm). As can be seen from the MPE result, this device passes the limit specified in 1.1310 at a distance of 0.0532and 0.0509 meter. Calculation:

30 x 0.6792 x 1 d= 10 x 377 = 0.0532m 30 x 0.4074 x 1 d= 12.5 x 377 =0.0509m
