Installation Tips:
1. User needs to prepare the welding tool at first.
2. Please be patient until the installation is complete.
3. The package is DIY kit. It need finish install by user.
4. The soldering iron can’t touch the components for a long time(1.0 second), otherwise it will damage the components.
5. Pay attention to the positive and negative of the components.
6. Strictly prohibit short circuit.
7. User must install the LED according to the specified rules. Otherwise some LED will not light.
8. Install complex components preferentially.
9. Make sure all components are in right direction and right place.
10. It is strongly recommended to read the installation manual before starting installation!!!
11. Please wear anti-static gloves or anti-static wristbands when installing electronic components.

Installation Steps (Please be patient install!!!):
Step 1: Install 1pc 39Kohm Metal Film Resistor at R1.
Step 2: Install 2pcs 10Kohm Metal Film Resistor at R2,R3.
Step 3: Install 1pc SOP-16 IC LM4863 at U1.There is a mark on one end of the IC and there is a mark on PCB where the IC can place on.These two marks are corresponding to each other and are used to specify the installation direction of the IC Socket.
Step 4: Install 1pc micro USB socket at J2.
Step 5: Prepare 6pcs pin header.
Step 6: Install 1pc Charging Module at J7 and fix by 6pcs pin header.
Step 7: Remove black fixed block from 6pcs pin header and fix Charging Module.
Step 8: Install 1pc 0.1uF Monolithic Capacitor at C2.
Step 9: Install 1pc 1uF 50V Electrolytic Capacitor at C1.Pay attention to distinguish between positive and negative.The Longer pin is positive pole.
Step 10: Install 1pc 3.5mm Audio Socket at J5.
Step 11: Cut a pin from 16Pin Female Socket.
Step 12: Install Female Socket at FM.Pay attention to the direction of the cut pin.
Step 13: Install 1pc Self-locking Button at S6.
Step 14: Install 5pcs 6*6*20mm Black Button at S1-S5.
Step 15: Install 1pc Self-locking Button Cap on Self-locking Button.
Step 16: Install 1pc Antenna at ANT.Note that the antenna should be installed on the front of the PCB.
Step 17: Install 1pc 18650 Battery Box at J1,J3.Pay attention to the positive and negative.Red wire is positive pole.
Step 18: Install 2pcs 15cm black Cable on speaker.
Step 19: Connect speaker to PCB at SP. The speaker does not distinguish between positive and negative.
Step 20: Install 1pc FM Audio Receiver on Female pins.Pay attention to the direction of the cut pin.
Step 21: Tear off the protective film on the surface of the acrylic shell.
Step 22: Install 4pcs M3*15mm Copper Pillar and 4pcs M3*10mm Screw on Acrylic bottom plate.
Step 23: Fixed speaker on acrylic bottom plate by 4pcs M3*6mm Screw.
Step 24: Install 3pcs M3*6mm Screw and 3pcs M3 Nut on Acrylic bottom plate.Note that the wire should not be placed between the PCB and the acrylic.
Step 25: Fixed main PCB on acrylic bottom plate by 3pcs M3 Nut.Note that the wire should not be placed between the PCB and the acrylic.
Step 26: Adjust the position of the battery box. Do not place the wires under the battery box. The wires can be moved to both ends of the battery box.
Step 27: Fix other acrylic plate by 6pcs M3*6mm Screw and 6pcs M3 Nut.
Step 28: Connect to power supply and enjoy the effect.
