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 88.1MHz to 107.9MHz, frequency interval is 0.1MHz. Operating Instructions: Connecting with all iPod models, PSP, MP3 players: 1.Insert one AAA battery into battery compartment of transmitter. 2.Insert one end of the supplied connection cable into Transmitter’s audio jack 3.Insert the other end of cable into your iPod/PSP/MP3’s headphone output jack Listening to music: 1.Turn on your car radio or home radio and select a suitable frequency (eg.88.1MHz). 2.Press for 3 seconds to turn on the FM Transmitter.⑤ 3.Press ③ or to sele④ct the frequency as same as radio’s (eg.88.1MHz). 4.Turn on the connected MP3 player. 5.Check signal quality, in case that quality is not satisfactory, try turn to a suitable FM Frequency. Press and hold (3 seconds) the or ①②buttons to save the current frequency. 2) Provide information on the device and its antenna. The transmitter has seven parts: memory button, forward frequency knob, 3.5mm audio jack, backward frequency knob, on-off switch, LCD display and battery box. The transmitter utilizes a wire as dipole antenna. 3) How is it installed? The transmitter is powered by 1 ̄ AAA batteries. It can be connected to audio source headphone 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. Antenna 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, frequency interval is 0.1MHz. We selected the low (88.1MHz) mid (98.1MHz) and High (107.9MHz) working frequency to measure the frequency. tune the knob 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 (music song). We have indicated the operating condition in the test report, see clause 5.3.

Operational Description

Operation Description TMP3FT-FS(Jack-703) Operation Frequency: 88.1M-107.9MHz Modulation Type: FM 1. The unit may be powered by a battery (DC1.5V). Internal DC/DC circuit increases voltage to 3.3V to supply the unit. The unit is in standby mode this moment. 2. When long press “POWER” button 3 seconds, MCU switches on electronically and supply local oscillating circuit and amplifier. The background light is on and to shut off after 5 seconds. MCU recalls the frequency of last use from PLL (31202) and HT1621. 3. R&L of audio signal is filtered by low-pass filter. One is input to local oscillating circuit. The other is input to MCU and is processed to output to local oscillating circuit too. The signal is modulated and amplified to match network. Its harmonics is filtered and it is transmitted by antenna. When no audio input, audio detecting circuit outputs a signal of level 1 to MCU. MCU counts time and will shut down the unit and LCD does not display after 60 seconds. The unit enters to standby mode. When audio input, audio detecting circuit outputs a pulse voltage to MCU, MCU will switch on and LCD displays the frequency of last transmission. 4. S1 and S3 are frequency + and – buttons. S2 and S4 are M1 and M2 memory buttons. Every button is pressed, MCU will control PLL IC and HT1621 to display the same frequency of transmission. At the same time, background is light on and to shut off after 5 seconds.
