FAQ:

Q: What is the transmission power of this device?

A:  The transmitter power is 50mW.
Q:What is the maximum open field range of this device in meters?

A: The maximum open field range of this device is about 50meters.

Attention:

Must connect the antenna before power on!

2  Make sure the antenna operating frequency and operating frequency to match the transmitterOtherwise it may affect the normal operation of the transmitter because the standing wave is too large!

3 Make sure the power supply is strong enough for the Fm transmitter!
