When the Push-to Talk button is pushed it sends out radio frequency (RF) signals. This device is authorized to operate at a duty factor not to exceed 50% in August 1996, the Federal Communications Commission (FCC) adopted RF exposure guidelines with safety levels for hand-held wireless devices. CAUTION : To maintain compliance with the FCC’s RF exposure guidelines, hold the transmitter and antenna at least 0.5 inches (1.25 centimeters) from your face, with the antenna pointed up and away from the face, if you wear the handset on your body while using the headset accessory, use only the manufacturers supplied belt clip for this product and ensure that the antenna is at least 1 inch (2,5centimeters) from your body when transmitting. This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter and may violate FCC regulations. This phone (device) has an output power of max 32mW, which no warning statements required. Now this phone (device) designed to be hold transmitter and antenna at least 0.5inchs from your Face. Therefore this phone (device) satisfies RF exposure compliance. √ IMPORTANT Read this manual before attempting to setup or use this instrument.

FCC ID: PE3DT-1R REPORT :THRU-412003 Page 2 of 22 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written Approval of THRU &ENGINEERING. Shielded interface cables were used in all cases except for cables connecting to the telephone line and the power cords. A test program was run which simulated a normal data transmission on a network. POWER LINE CONDUCTED INTERPERENCE: The procedure used ANSI STANDARD C63,4-1992 using a 50uH LISN. Both lines were observed. The bandwidth of the spectrum analyzer was 10 KHz with an appropriate sweep speed. The ambient temperature of the UUT was 9 with a humidity of43%. BANDWIDTH 6.0dB : The measurement were made with the spectrum analyzer’s resolution bandwidth (RBW)=300 KHz and the video bandwidth (VBW) =300 KHz and the span set as shown on plot. POWER OUTPUT: The RF power output was measured at the antenna feed point by removing the permanent antenna and connecting the UUT to a spectrum analyzer, HP Model No.8866B, RBW=3MHz, VBW>or=RBW, span=5MHz. ANTENNA CONDUCTED EMISSIONS: The RBW=100KHz, VBW > or = RBW and the spectrum was scanned from 30MHz to the 10 th Harmonic of the fundamental. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a preselector. The bandwidth (RBW) of the spectrum analyzer was 100KHz up to 1GHz and 1.0MHz above 1 GHz with an appropriate sweep speed. The VBW above 1.0 GHz was = 1.0 MHz. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The ambient temperature of the UUT was 9 with a humidity of 43%. 15.247(d) POWER SPECTRAL DENSITY: The peak within the pass band was located with a RBW set to 30KHz and a span of 5 MHz, slightly greater than the 6dB bandwidth, then the emission was centered on the display and the span and RBW reduced. A 2MHz span, 3KHz RBW, and a sweep time to sweep time set to 670 seconds. Since spectral line spacing could not be resolved, the noise power density method was used. The response was then plotted, a correction factor of measured using the noise power density and adding the correction of 35dB and any attenuation used was added. 15.247(e) : PROCESSING GAIN, This gain is supplied by the manufacturer of the UUT.
