ME2-SF280WIRELESS STEREO MUSIC ADAPTER

Owners Manual For SOUND FEEDER SF280 Mini USB Wireless Music Adapter I. INTRODUCTION SF280 SOUND FEEDER Mini USB Wireless Adapter is a multi-purpose, USB-powered FM stereo music transmitter suitable for use with many types of consumer audio equipment. Use SF280 to transmit the music from your portable music player—including laptop computer, PDA, MP3 player, compact disc player, etc.—to any nearby FM receiver, whether in the car or at home. II. SET UP & OPERATION 1. Select a suitable transmission frequency for your area. We suggest you start with one of the frequencies in the 88-89MHz-band area since these stations are more likely to be unused in your area. Turn the frequency switch on the Sound Feeder to point to the letter or number that corresponds to the desired frequency listed on the backside of the Sound Feeder. 2. Then insert the Sound Feeder into the USB slot on the Car power adapter and insert the car power adapter into the lighter socket of a vehicle. 3. Then use the audio cord provided to connect the Sound Feeder to the headphone jack or line out jack of your portable music player. 4. Turn on your music player and make sure it has a medium (disc, tape, etc.) or an electronic file to produce sound. 5. Turn on your FM radio to medium volume and set it to the FM frequency your have selected in step 1 above. You should hear your music played over the FM radio. If you find that another broadcaster is already using the frequency you selected in step 1 above, then select another frequency. III. OPERATING TIPS Once you have discovered the best transmitting frequency for your area, you can make a note of the frequency and then directly tune to that frequency in the future or store this frequency as one of your preset stations. If you drive to another city and are listening to Sound Feeder, you may encounter interference from a radio station in that city that is using the same frequency that you are. If that is the case, you may need to select another frequency out of the total of 12 possible frequencies. VI.

Radiated test procedure: The EUT, associated cables and peripheral devices are placed on the supporting table and any support equipment is placed off the site. The EUT is turned on and any necessary operating or test software installed and allowed to warm up. The EUT is pre-scanned in our ferrite tile lined chamber where it is rotated 360 degrees and examined in both horizontal and vertical polarization, all emission frequencies are identified and recorded. The EUT is then moved to the OATS and the frequency band from 30 MHz to 40 GHz is scanned, all frequencies identified in the chamber are investigated, as well as harmonic frequencies of the EUT. When an emission is found the emission is maximized by varying the bundle position of the connecting cables, the antenna height, the antenna polarization (vertical and horizontal) and the table orientation (360 degrees). The maximum reading is recorded and the next signal is searched for. Conducted test procedure: The power line of the EUT is connected to the LISN (Line Impedance Stabilization Network). A measurement of the emissions are made from the power line for both phase and neutral on the analyzer in the frequency range from 150 kHz to 30 MHz. The maximum readings are recorded for each phase. All measurements are made according to the procedures defined in: "ANSI C63.4-2001 American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz” Page 7 of 36 Compliance Worldwide, Inc. – 357 Main Street – Sandown, NH 03873 (603) 887 3903 Fax 887 6445 http://www.cw-inc.com TEST NUMBER - 339-04 RevB RSS 210/ FCC Part 15 TEST LIMITS 1.
