FM radio
Frequency Modulation (FM) is a close-range high-fidelity broadcasting system. Its advantages are beautiful sound quality and strong anti-interference ability.
The frequency of FM broadcasting in our country is 87~108MHZ, the frequency interval is 0.1MHZ, and the transmitting power of the station is between several hundred watts to 20 kilowatts.
The standard configuration includes the host, manual, after-sales service guarantee, and certificate of conformity.
In addition, a dry battery and a radio protection bag are provided(Available in black and white)
(Dry battery is ordinary dry battery)
