Attention
:
1
Must connect the antenna before power on!
2
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!
3
Make sure the power supply is strong enough for the Fm transmitter!
