About Electromagnetic Interference (EMI) This device is designed and manufactured not to exceed the exposure limit for radio frequency energy, which is set by the Federal Communications Commission of the U.S government. FM Transmitter V10M10_IM_EN_09192006 www.i-Luv.com -4 - USER SAFETY GUIDE About Electromagnetic Interference (EMI) – Continued The term “EMI” is short for the electromagnetic interference caused by the electromagnetic field generated by electronic devices. In fact, most electrical appliances and devices emit electric and magnetic fields, and most of modern electronic devices are susceptible to electromagnetic interference (EMI) if they are inadequately shielded or designed. • If you use any personal medical device, such as a pacemaker, please consult the manufacturer of the device to determine if it is adequately shielded from electromagnetic interference. Your physician may assist you in obtaining this information. • Please turn off this device if you are instructed to do so, especially on an airplane and in a hospital. • Please keep away from the medical instruments in a hospital or medical unit while using this device. FCC Notices to U.S. Users This device complies with Part 15 of the FCC Rules.

1) How does this device operate? The FM transmitter is a FM stereo transmitting configuration, which radiates FM wave on the air by modulating the any required signal to the carrier signal. The transmission frequency is set from 88.1 to 107.9MHz. Operating Instructions: Turning on/off the FM Transmitter This unit is designed to be powered by your iPod. When connected to your iPod, it automatically turns on. When disconnected, it automatically turns off. If there is no audio input signal until 1 minute after connected to your iPod, this unit automatically enters the standby mode. In the standby mode, it stops transmitting and the LCD turns off. If there is an audio signal, it automatically wakes up and starts transmitting the music. Setting up the Preset Memory You can store two FM frequencies in the preset memory and easily call them up later by pressing one of the preset buttons. The default frequency for Preset 1 is 90.1MHz, and 98.1MHz for Preset 2. To change the default preset frequencies with other frequencies, follow the instructions below: 1. Connect the FM transmitter to your iPod. The LCD screen turns on. 2. Select a frequency using the “<” (Frequency Down) and “>” (Frequency Up) buttons. 3. Press and hold “•” (Preset 1) button until the selected frequency display blinks. 4. Select a frequency using the “<” (Frequency Down) and “>” (Frequency Up) buttons. 5. Press and hold “••” (Preset 2) button until the selected frequency display blinks. Transmitting Your Favorite Songs to a Nearby FM Radio 1. Connect the FM transmitter to your iPod. 2. Play a song on your iPod. 3. Press one of the preset buttons. 4. Tune your FM radio to a FM frequency stored on the selected preset memory, and listen to your favorite music. . 2) Provide information on the device and its antenna. The transmitter has seven parts: 1. • (Preset 1) button 2. < (Frequency down) button 3. Mini USB port 4. •• (Preset 2) button 5. > (Frequency up) button 6. LCD screen 7. 30-pin connector The transmitter utilizes PCB Layout as antenna. The antenna was soldered to main board. Antenna 7 6 1 5 4 3 2 3) How is it installed? The transmitter is powered from iPod. It can be connected to iPod 30pin dock. 4) What test procedure was used? ANSI C63.4, the test was performed in a semi-anechoic chamber. 5) If tested in a car, how was it configured/tested? Not tested in a car, it was tested in a semi-anechoic chamber. The EUT has been additionally tested / verified and does work in a typical car. 6) Was the tuning range properly verified? The test lab should indicate in the report that the tuning controls were manually adjusted to verify maximum tuning range. The FM transmitter is a FM stereo transmitting configuration, which radiates FM wave on the air by modulating the any required signal to the carrier signal. The transmission frequency is set from 88.1 to 107.9MHz. We selected the low(88.1MHz) mid(98.1MHz) and High(107.9MHz) working frequency to measure the frequency. press the “<” (Frequency Down) and “>” (Frequency Up) button to select the transmission frequency . We have indicated the testing in the test report, see clause 6. 7) Was the bandwidth properly tested with maximum audio input? The test was performed with the maximum audio input. And play typical audio signal(‘Highway Blues’ from sample music of windows XP). We have indicated the operating condition in the test report, see clause 5.3.

Transmitter Operation Description Operation Frequency: 88.1M-107.9MHz Modulation Type: FM The audio frequency signal is imported from the 1 st and 24 th foot of IC2, and exported by the 5 th foot in the format of mix-frequency signal, then get to the cathode frequency modulation of the trans-capacitance diode via C10、R6, it is also controlled by the lock-photograph loop signal DATA which passes by the MPU of IC1, when IC2 receive the modulating surge signal that exported from 7 th foot, it will pass this signal through C15,C16 and the 10 th foot of TX-VCO, and then compare to the inner benchmark frequency, at last, the lock-photograph loop press-control voltage FX-PLL is received. The adjusted transmit frequency signal is added to the basic-pole of C18 by Q2 to magnify the power, the magnified signal is passed by C19, L3, and then transmitted around by the antenna, this signal will be received by radiogram.
