ATTACHMENT B to File No.: T34121-01-00HU Maximum permissible exposure (MPE) Model: WRTZ - 1000 and Antenna Type No. 520 10073 1.1 For test instruments and accessories used see section 6 Part CPC 2. 1.1.1 Description of the test location Test location: AREA4 1.1.2 Applicable standard According to FCC Part 15, Section 15.247(i): Systems operating under the provisions of this section shall be operated in a manner that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. The test methods used comply with ANSI/IEEE C95.1, “IEEE Standard for Safety Levels with respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz”. This test report shows the compliance with the limits for Maximum Permissible Exposure (MPE) specified in FCC Part 1, Section 1.1310 and the criteria to evaluate the environmental impact of human exposure to radio- frequency (RF) radiation as specified in FCC Part 1, Section 1.1307(b). 1.1.3 Description of Measurement The maximum total power input to the antenna has been measured conducted as described in clause 5.3 of this document. Through the Friis transmission formula, the known maximum gain of the antenna and the maximum power, the MPE can be calculated in a defined distance away from the product. Pout * G Friis transmission formula: Pd = 4*Π *r2 where Pd =power density (mW/cm2) Pout = output power to antenna (mW) G = gain of antenna (linear scale) r = distance between antenna and observation point (cm) mikes-testingpartners gmbh ‹ Ohmstrasse 2-4 ‹ D-94342 Strasskirchen ‹ Tel:+49-9424-9481-0 ‹ Fax:+49-9424-9481-240 ‹ Rev.

The EUT is designed to be used that radiating structures are more than 20 cm outside of the body of the user. (r = 20 cm). Note: The manufacturer shall state in the manual the minimum cable length for each antenna. Aditionally this shall be stated on the label of the EuT. The requirements are FULFILLED.
