Installation Tips:
1>.User needs to prepare the welding tool at first.
1.1>.Soldering iron (<50 Watt)
1.2>.Rosin core (“radio”) solder
1.3>.Wire cutters
1.4>.Wire strippers
1.5>.Screwdriver
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. Other wise 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: Identify the positive and negative poles of the LED.
1.1>.LED front: It is the negative pole where there is a greed mark.
1.2>.PCB mark: It is the negative pole where the round pad on.
Step 2: Install any 4pcs SMD 0805 LED on‘ R’ pads on 3pcs PCB.
You can choose to install in any of the three LED colors. Tips:
2.1>.Place tin on one pad.
2.2>.Hold LED with tweezers, melt tin just now with a soldering iron at the
same time.
2.3>.After aligning each pad and pin, use tweezers to place the capacitor on
PCB.
2.4>.Remove iron and hold LED by tweezers for about 5 second to waiting for
fix pin.
2.5>.Fix another pin and pad. .
Step 3: Install another 4pcs SMD 0805 LED on‘ Y’ pads on 3pcs PCB by the same methods.
Step 3: Install another 49cs
SMD 0805 LED on‘ Y’ pads on 3pcs PCB by the same methods.
Step 4: Install the last 4pcs SMD 0805 LED on’ G ‘pads
on 3pcs PCB by the same methods. 
Step 5: Install 1pcs S9012 2T1 SOT-23 Transistor at 01. 
Step 6: Install 1pcs SMD 0805 472 4.7Kohm Resistor at R5.
Step 7: Install 4pcs SMD 0805 471 470ohm Resistor at
R1,R2,R3,R4.
Step 8: Install 1pcs DIP-16 STC8G1K17 IC Controller. There is a dot mark on
one end of the IC and there is a gap mark on PCB silk screen 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. 
Step 9: Install 2pcs Toggle Switch.
Power Switch:
ON/OFF work power, switch next LED Flashing Status, playing next music at the
same time.
Music Switch:
ON/OFF music and switch next music. 
Step 10: Install 1pcs CR2032 Battery Socket. Pay attention to the installation
direction. 
Step 11: Install 1pcs Active Buzzer on PCB another side.
Note: Label ‘ + ‘ connect to the square pad.
Step 12: Install 2pcs 4Pin
Male Pin on the smaller PCB. Pay attention to the installation direction.
Step 13: Fix one on the biggest PCB. Note that two PCBs are in a vertical relationship. Step 14: Fix another on
the biggest PCB. Note that the two PCBs are in a vertical relationship.
Step 15: Install 2pcs
CR2032 or CR2025 batteries as shown. Note: The positive electrode of the
battery contacts the metal spring of the battery holder.
It does not include batteries, users need to prepare their own batteries.
