Installation Steps(Please be patient install!!!):

1>.Step 1: Install 1pcs SMD component SOP23-5TP4054at U1. Verify and confirm the installation direction of TP4054.

2>.Step 2:Randomly choose a pad on the PCB, and then melt the solder on this pad.

3>.Step 3:Fix TP4054: Use a soldering iron to melt tin on the pad just now and hold TP4054with tweezers in the other hand to place/press on U1 to prevent movement. Take care to match and align each pads. Then remove soldering iron. Then remove tweezers after solder tin cooling and solidification.

4>.Step 4:Connect others pads on TP4054to pads on PCB by tin and soldering iron.

5>.Step 5: Install 1pcs510ohm Metal Film Resistor at R2.

6>.Step 6: Install 2pcs 10Kohm Metal Film Resistor at R1,R2.

7>.Step 7:Install 1pcs micro USB socket at ‘micro’or J2.

8>.Step 8: Install 2pcs 0.1uF Monolithic Capacitor at‘104’or C1,C2.

9>.Step9: Install 1pcs 1pcs 3mm Blue light LED at D2.Note: The longer pin is positive pole which need connect to ‘+’pad.

10>.Step 10: Install 1pcs 1P2TSK-12D07 Switch atS7.

11>.Step 11: Install 1pcs 3.5mm AUX Audio Socket at J5.

12>.Step 12: Install 5pcs 6*6*20mmBlack Button atSP+/SP-/P+/P-/AUTO or S1-S5.

13>.Step 13: Install 1pcs FM Receiver LCD Display Moduleat FM.

14>.Step 14: Install 3.7V 250mAh Lithium polymer battery. Red wire connect to BAT+ pad and black wire connect to BAT- pad.

15>.Step 15: Tear off the protective film on the surface of the acrylic board.

16>.Step 16: Fix 4pcs Nut and 4pcs M3*6mm Screw on Acrylic bottom board.

17>.Step 17: Place PCB on M3*6mm Screw.

18>.Step 18: Fix 4pcs M3*10mm Copper Pillar.

19>.Step 19: Fix other acrylic plate by 4pcsM3*6mmScrew.
