TEST REPORT No.: (5210)166-0896 Test Results Radiated Emissions (Fundamental) Test Requirement: FCC Part 15 Section 15.227 Test Method: ANSI C63.4 Test Date(s): 2010-07-05 Temperature: 32.0 oC Humidity: 65.0 % Atmospheric Pressure: 100.6 kPa Mode of Operation: Transmission mode Tested Voltage: 9Vd.c. (“6F22” size battery x 1) Test Method: Radiated emissions measurements are investigated and taken pursuant to the procedures of ANSI C63.4 – 2003. The equipment under test (EUT) was placed on a non-conductive turntable with dimensions of 1.5m x 1m and 0.8m high above the ground. 3m from the EUT, a broadband antenna mounting on the mast received the signal strength. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, For battery operated equipment, the equipment tests shall be perform using new battery. The turntable was rotated to maximize the emission level. The antenna was then moving along the mast from 1m up to 4m until no more higher value was found. Both horizontal and vertical polarization of the antenna were placed and investigated. For below 30MHz, a loop antenna with its vertical plane is place 3m from the EUT and rotated about its vertical axis for maximum response at each azimuth about the EUT. And the centre of the loop shall be 1m above the ground.

TEST REPORT No.: (5210)166-0896 26dB Bandwidth of Fundamental Emission Test Requirement: FCC 47 CFR 15.227 Test Method: ANSI C63.4:2003 (Section 13.1.7) Test Date(s): 2010-07-03 Temperature: 24.0 oC Humidity: 65.0 % Atmospheric Pressure: 101.3 kPa Mode of Operation: Transmission mode Tested Voltage: 9Vd.c. (“6F22” size battery x 1) Test Method: The bandwidth is measured at an amplitude level reduced from the reference level by a specified ratio. The reference level is the level of the highest amplitude signal observed from the transmitter at the fundamental frequency. Once the reference level is established, the equipment is conditioned with typical modulating signal to produce the worst-case (i.e. the widest) bandwidth.

TEST REPORT No.: (5210)166-0896 Duty Cycle Correction During 100msec: Each function key sends a different series of characters, but each packet period (49.2msec) never exceeds a series of 53 (0.7msec) pulses. Assuming any combination of pulses may be obtained due to encoding the worst case transmit duty cycle would be considered (53x0.7msec) per 49.2msec=75.4% duty cycle. Figure A through B show the characteristics of the pulse train for one of these functions.
