The fundamental frequency of transmitter emitted is due to a press on button of the EUT. The emitting time of fundamental frequency is less than 5 seconds pursuant to FCC Part 15.231(a). There are security codes for avoiding the possibility of duplicating codes in adjacent systems. The coding must be matching with the companion receiver. While testing the EUT was adjusted at a position which transmit the maximum emission. 1.3Description of Support Equipment The EUT itself forms a system. No support equipment is requited for its normal operation. Test Report -------------------------------------------------------------------------------- 4/20 Report No.: G2115962 (Tx) Training Research Co., Ltd., TEL: 886-2-26935155,Fax: 886-2-26934440 1.4Test Procedure All measurements contained in this report were performed according to the techniques described in measurement procedure of ANSI C63.4 1992 section 13 1.5Location of the Test Site The radiated emissions measurements required by the rules were performed on the three- meter, Anechoic Chamber (Registration Number: 93906) maintained by Training Research Co., Ltd. 1F, No. 2, Lane 194, Huan-Ho Street, Hsi-chih, Taipei Hsien 221, Taiwan, R.O.C. Complete description and measurement data have been placed on file with the commission. The conducted power line emissions tests and other test items were performed in a anechoic chamber also located at Training Research Co., Ltd. No. 2, Lane 194, Huan-Ho Street, Hsi-chih, Taipei Hsien 221, Taiwan, R.O.C. Training Research Co., Ltd. is listed by the FCC as a facility available to do measurement work for others on a contract basis. 1.6General Test Condition The conditions under which the EUT operates were varied to determine their effect on the equipment’s emission characteristics. The final configuration of the test system and the mode of operation used during these tests were chosen as that which produced highest emission levels. However, only those conditions that the EUT was considered likely encounter in normal use were investigated.

The EUT was placed on a wooded table which is 0.8 meters height and a bi-log periodic antenna was used distance about 3 meters for receiving. While testing EUT was set to transmit continuously. Various key configurations were also investigated to find the maximum duty cycle. The resolution bandwidth and video bandwidth of the spectrum analyzer was all set to 1MHz to encompass all significant spec…
