 APP installation and usage instructions (Apple mobile phones pay attention to the second and third steps, there are differences!):

   When using the Bluetooth APP, please turn off the mobile phone''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s own player, and then use the APP to pause playback and select music（No panel buttons or remote control）; Otherwise there will be the phenomenon of playing two music at the same time

1）First on the phoneApplication market（Such as “application treasure” etc.）Search for “Bluetooth Companion” the suffix shows JL or Jerry, click to download and install it on your phone;

2) Press the MODE button to switch to Bluetooth（bluet）, And also hear “beep, beep or beep"; the phone must also enable the Bluetooth detection of the phone so that the phone can be detected by the device, and then enter the Bluetooth menu-search for devices or paired devices, search After arrival（M01BT）“touch to pair”also hear “beep”to complete pairing; not a smartphone（Android system）To enter the password -0000, the product Bluetooth device name M01BT;

3)Back to the mobile phone APP interface, double-click the software to open it and it will search for ”M01BT” (Apple mobile phone is “BT_BLE, both M01BT and BLE_NAME must be connected at the same time)；

4) Enter to play Bluetooth mode and submenu（Three small dots）；

5) When you click the corresponding menu on the phone, the product will enter the corresponding mode

6) U disk or TF device mode and sub-menu function selection（Three small dots）

7) Radio mode and sub-menu function selection（Three small dots）

8) External audio AUX input

Note: Not a smart phone（Android system）To enter the password -0000; product Bluetooth device name M01BT
Pay special attention to one:
    1: Working voltage 12V: DC 7V-12V, 5V: 3.7V-5V; current 800MA-1A. If the current is not enough, there will be phenomena such as skipping or remote control failure or abnormal Bluetooth reading.（If you have this problem, please check your power supply）; The voltage cannot be higher than the highest value of the voltage range required by the product, otherwise the main chip and related components will be damaged.      
    2: The module power ground and signal ground are separated, and there are separate resistors to make it easier to choose different power amplifiers（See the R32 0 ohm resistor on the board）, Now the shipment has been connected with 0 ohms. Some power amplifiers have noise. Please use a separate power supply to power the decoder board when using it. If it is the same power supply as the amplifier, please connect the audio output ground of the decoder board to the power ground ("AGND" and "GND" R32 0ohm resistor) must be opened here before wiring (operate with the power off); and if you don’t understand the wiring or other problems or can’t handle it well, you can contact us at any time）
    For Taoyou who are not sure about the power supply, in order to make the product work properly, it is recommended to use our power supply. You can put the power supply and the host into the shopping cart and take a picture. The power supply is connected to https ://item.taobao.com/item.htm?spm=a1z10.5-c.w4002-2821347443.18.Be9uky&id=38888023702
Pay special attention to two:
Car modification attention    
  Power supply: Do not directly connect the power supply to the battery, cigarette lighter, and car lock. There are precedents for the unstable voltage in these three places, and there are precedents that some cars have interference. Please pay attention ! ! Please connect to the regulated and rectified power supply (usually 8-10V) in the CD or cassette player. The 12V electricity on the car, including the pillars behind the CD iron shell, are not stabilized and rectified; remember!!; If you can’t or don’t find the corresponding power supply, you can contact us   
   If you are looking for the audio signal cable in the CD player when you are refitting on a car, if you are not sure which line is the audio input, it is recommended that the left and right audio output lines of the decoder board are connected in series. Electrolytic capacitors within 10UF to protect the decoding audio output module（Those who need to receive a message provide electrolytic capacitors free of charge, and no remarks without a message are not provided）
Three: Attention to home modification
power supply
A: When connecting from the original power amplifier, pay attention to the DC power supply after the power amplifier is rectified; do not directly connect the power supply at the transformer or before rectification. The power at the transformer and before the rectification is still AC power, and the router is also AC power. Can not directly supply power to the decoder board, this will burn out the product)
B: The power supply needs full-wave rectification, and the filter has a capacitor of more than 1000UF to supply power to the decoder board. If a poorly filtered power supply has a direct impact on the radio and decoding sound quality
About car audio interference（Common Land Phenomenon）, Depending on the car condition, it can be handled as follows
C: If the electricity is not taken from the CD circuit, you can add a DC-DC isolated power supply.
D: The audio output is connected with a 1:1 isolated audio transformer (note that it is a dedicated audio transformer).
E: Connect a BA3121 circuit (noise reduction circuit)
Four: Car and home modified audio wiring principle:
A. The audio line is connected to the circuit board: the decoder board audio output “R-OUT/GND/L-OUT” is connected to the audio input of your amplifier“R-IN/GND/L- IN” corresponds to the connection; then the sound source on your original power amplifier will be disconnected, and the audio output of the undecodable board and the sound source of the original power amplifier are connected in parallel to the power amplifier at the same time, so that the chip or other components will be burned out when the power is turned on; If you need to connect other audio sources, you must connect the audio source signal to the audio input of the decoder board, remember! !
B. Connect with 3.5 audio cable: connect the audio output on the decoder board “R-OUT/GND/L-OUT” with “3.5 audio cable” directly and then plug it into your amplifier Or the car''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s “AUX” hole, this is the simplest and most convenient wiring method, it is recommended to use this connection method
