HC Telecom Co., Ltd. e-mail : [email protected] fax : +82 32 663-4489 Wireless Audio Sender - FM band Features FM Band full channels (88.0 ~ 108.0MHz) available Channel selection Up (1 or 0.1MHz) / Down (0.1MHz) Excellent sound by wireless solution LCD display (Frequency, Low Battery) Back Lighting Max. 8 hours play with one 1.5V AAA battery TX power : less than 0.1mW Allowable distance : 3m User’s guide 1. Plug the Audio Sender’s plug into your portable music player. 2. Turn on the power by pressing button (1) for at least 2 seconds. (Insert a 1.5V AAA battery before turning on the power.) 3. Turn on your car or home radio. 4. Select and save your car or home radio’s frequency to a channel that has no broadcasting on it. 5. Match the Audio Sender’s frequency with your radio’s frequency by pressing button (1) or (2). (Frequency goes up by 1MHz by long pressing the button (2).) 6. Turn on your portable music player (i.e. portable CD player, MP3 player, etc.,) and play the music. (Due to the characteristics of FM, for better quality sound, you should adjust the volume level by your radio’s volume switch while leaving your portable player’s volume to lower than medium level.) ** Change the frequency of your portable music player and car or home radio if you hear interferences. ** The Audio Sender’s wire performs as Antenna, so do not make the wire is rolled.

FCC ID : ON7HCF-3000 REPORT :THRU-402004 Pages: 2of 12 Page 2 of 10 TEST PROCEDURE GENERAL: This report shall NOT be reproduced except in full without the written approval of ThruLab & Engineering.. RADIATION INTERFERENCE: The test procedure used was ANSI STANDARD C63.4-1992 using a HEWLETT PACKARD spectrum analyzer with a preselector. The bandwidth of the spectrum analyzer was 100 kHz with an appropriate sweep speed. The analyzer was calibrated in dB above a microvolt at the output of the antenna. The resolution bandwidth was 100KHz and the video bandwidth was 300 kHz. The ambient temperature of the UUT was 63 degrees with a humidity of 49%. FORMULA OF CONVERSION FACTORS: The Field Strength at 3m was established by adding the meter reading of the spectrum analyzer (which is set to read in units of dBuV) to the antenna correction factor supplied by the antenna manufacturer. The antenna correction factors are stated in terms of dB. The gain of the Preselector was accounted for in the spectrum analyzer meter reading. Example: Freq (MHz) METER READING + ACF = FS 33 20 dBuV + 10.36 dB = 30.36 dBuV/m @ 3m ANSI STANDARD C63.4-1992 10.1.7 MEASUREMENT PROCEDURES: The unit under test was placed on a table 80 cm high and with dimensions of 1 m by 1.5 m. The table used for radiated measurements is capable of continuous rotation. When an emission was found, the table was rotated to produce the maximum signal strength. At this point, the antenna was raised and lowered from 1 m to 4 m. The antenna was placed in both the horizontal and vertical planes. The situation was similar for the conducted measurement except that the table did not rotate. The EUT was setup as described in ANSIC63.4-1992 with the EUT 40 cm from the vertical ground wall. Not Applicable battery operated. THRUlab & Engineering.
