How to use Mini FM Transmitter

Definitely. Mini FM Transmitter is coin-sized for us to carry and use. Moreover, it is very high sensitivity. It can detect the footsteps in the quiet room and sound of the wind clearly outside. If you use the wire as the antenna, the antenna’s length can be appropriately adjusted according the actual environment. FMUSER M01 is the typicle example of Mini FM Transmitter. We will introduce how to use Mini FM Transmitter by example of FMUSER M01.

Usage Method

You could connect 9V batteries with the FMUSER M01 Mini FM transmitter and put it at somewhere you like, then open your receiver and adjust to the same frequency. After doing above steps, you can hear the sound broadcasted by the FMUSER M01 from your receiver.

Description

1. Working voltage: 1.2V—–9V

2. Working current: 3mA~1.2V, 25mA~9V

3. Broadcast frequency rang: 60MHZ—-128MHZ

Precautions

1.  Lock the 9V battery on the transmitter. The yellow wire is used as antenna, please keep it straight during use. Keep the transmitter far away from metal objects or structure, this will help transmitting longer distance. We can also keep it higher from ground to get farther distance.

2.  During test, please make sure the receiver frequency should be the same as transmitter’s. The test could be hearing the clock ticking in a quiet room, no need to use a special audio resource.

3.  When doing test, please make sure the transmitter and receiver should be away from each other at least 10 meters, otherwise it could cause howling or hum. When finding the best transmitting frequency, please adjust the frequency finely manually, do not use receiver to do automatic search in case it gets too much spurious signals and influence the sound effect.

4.  Please avoid receiving very loud signals, this transmitter is preferably suitable for tiny sounds like clock ticking.

5.  Please keep transmitter away from strong audio resource because of its high sensitivity, otherwise the big input will cause distortion of sound and lots of spurious will get in.

6.  The transmitting frequency will be affected by the battery voltage, when voltage changes, the transmitting frequency might deviate a little, please kindly note that during use. Generally it’s within acceptable range.
