4. “MODE”: Mode switching, each time you press to switch the working mode;
5. IN: Input, one-wire interface, 5V voltage and external sound can be input from this interface.
Wiring instructions:
1. 12V connection: 2P socket, +12V is connected to the positive pole of the 7V-12V DC power supply, and GND is connected to the negative pole of the power supply;
5V(3.7-5V)Connection method: connect BAT+ to 5V+ without header, connect BAT- to GND(Ground), Respectively connect to the positive/negative 5V power supply(GND)
Special note: The current is 600MA-1A, if the current is not enough, there will be phenomena such as skipping or remote control failure.(If you have this problem, please check your power supply); See the picture above, pay special attention to the product cannot be connected to two sets of power supplies at the same time(5V/12V choose one)The voltage cannot be higher than the required voltage value of the product, otherwise the main chip and related components will be damaged!
Tips: If it is modified to a car, you only need to connect the 12V voltage to the 12V voltage input terminal of the decoder board at the position where the car is installed with the radio.
1,If you connect directly to the battery, please add a 7812 regulator board, the current is stable, there is no current sound, and the effect is good. If you need it, please take the link below:

2,If you connect the battery directly to the battery, please connect a 4007 diode and a 2.2 ohm 2W resistor in series to limit the current, but the effect is not good.See the picture below for details, you need to send resistors and diodes(Components), Please contact customer service for instructions or remarks!
2. 3P seat: R-IN connects to the right sound channel of the external sound, GND connects to the external sound ground, and L-IN connects to the left sound channel of the external sound;
3. 5P socket: R-O is connected to the right channel output, G is connected to the audio ground, and L-O is connected to the left channel output; G is the power ground, and V is the 5V output (this 5V output can not be connected if it is not available).
(Note: 5V output when connected to 12V)
4. The ANT white pad on the side of the 3P seat is where the radio antenna is welded. The radio antenna can be a copper wire or whip antenna of more than 1 meter.
Radio operation instructions:
1. Weld the radio antenna first;
2. Press the MODE button to turn to the radio mode;
3. Press the PLAY/PAUSE button to search and store all channels in all channels;
4. Press the previous or next button to go to the previous or next station;
Note: The radio effect varies with different geographic environments. The radio may not be received in places with weak or no signal, so please be careful!
