PRODUCT FEATURES

FM transmitter module
Transmit power : 3mW Operating voltage : DC 3V-16V Working current : 16mA

Instructions for use:
K1: short press , plus frequency 0.1MHz, long press , plus frequency 1MHz;
K2: Short press , reducing the frequency of 0.1MHz, long press , reducing the frequency of 1MHz;
K3: Short press , volume plus a stall current emission frequency ( total volume 4 files ) , press , display ;
K4: Short press , volume down a gear ( total volume 4 files ) , press , restore factory settings , the frequency of 99MHz, Volume 3 files ;

Module using the digital tuner, there will be no frequency offset, run frequency, cling to the antennas do not have any influence, need welding the antenna when use , the antenna length recommendation 75CM, if you use doubles as a transmitting antenna signal input line, need to connect the jumper beside the C6.

This plate shows the frequency, is 4 blue LED indicates that, if the current transmission frequency is 87.5M, long press K3, second LED slowly flashes 8 times, and third LED slowly flashes 7 times and 4th LED slow Flash 5 times. When viewing frequencies, the current normal launch, without any effect.

The transmitter module, using United States production launch stereo IC, stereo launched, transmitting frequency adjustable from 76MHz to 108MHz, whether the treble, or bass, and all have a great performance, great sound, distortion and signal to noise ratios are in line with GB, up to broadcast standards

Note on volume adjustment:

Audio signal inputs with 4 volume, minimum volume 1 document 4 document the loudest, the factory default in 3 gear, such as distortion discovered listening to, you can decrease the volume by one notch, to avoid distortion. (Input level is too high, will be distortion caused by over-modulation, audio input signal standard value is 1000mVP-P), short press K3 or K4, corresponding to position the lights flash, says it has operations in place, if the LED lights Flash 3 times, indicating current is minimum or maximum.

This product has a regulator circuit, regardless of input voltage is high, is the result of constant voltage supply circuit after use, under favorable conditions, Troy brand radio receiver, distance is 100 meters, using a mobile phone's built-in radio receiver, distance is 50 m. (Note: the distance from the antenna, topography, weather and other conditions vary)

Other notes: ...

matched with the transmitter module receiver wired microphones microphone core (moving coil) ...

as FCC test requirements, resistor R1 can play a relevant role ...
