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.

Must connect the antenna before power on! Make sure the antenna operating frequency and operating frequency to match the transmitter. Otherwise it may affect the normal operation of the transmitter because the standing wave is too large!

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