Make sure SOP-8 NY3P Music IC has been installed on PCB.

Install 8pcs 100ohm Metal Film Resistor at R1-R4,R7-R10.

Install 2pcs 10Kohm Metal Film Resistor at R5,R6.

Install 1pcs DO-35 1N4148 Diode at D5,D6.

Pay attention to the installation direction. Note: The black mark on Diode and the white mark on PCB are

corresponding.

Install 1pcs DIP-28 IC Socket at MCU.There is a mark(notch) on one end of the IC Socket and there is a mark(curved silk screen printing) on PCB where the IC Socket can place on.These two marks are corresponding to each other and are used to specify the installation direction of the IC Socket.

Identify the positive(anode) and negative(cathode) lead of LED.The leads of the LED must be installed correctly, otherwise the LED cannot be turned on.Here are

four methods as following:

6.1>.According to the length of the LED lead to distinguish. The longer pin is positive(anode) lead. The shorter pin is negative(cathode) lead.

6.2>.Identify the negative(cathode) of the LED is to look into the plastic case where one can see that the negative(cathode) is much thicker/bigger inside the plastic case

than the anode lead.

6.3>.Identify by edge of plastic case.The negative(cathode) lead of the LED should be the pin nearest the flat on the plastic case.

6.4>.Test by 3V battery or multimeter.The pin is positive(anode) lead which has connect to the positive of 3V if LED can light up after connect 3V power supply.(LED should

not be powered directly from the 3V for a short time:less then 0.5second)

6.5>.It is positive(anode) where the white mark “+” pointing to on PCB.

Install 4pcs 5mm Red/Green/Yellow/Blue LED at D1-D4. Note: The longer pin connect to ‘+’ pad. LED color be placed randomly

Install 3pcs 0.1uF 104 Ceramic Capacitor at C1-C3.

Install 1pcs TO-92 S8550 Transistor at Q1.

Install 1pcs TO-92 S9013 Transistor at Q2.

Install 1pcs TO-92 HT7550-1 Voltage regulator at U1.

Install 1pcs 470uF Electrolytic Capacitor at C4.

Note: Pay attention to distinguish between positive and negative. The Longer pin is positive pole.

Install 1pcs 10uF Electrolytic Capacitor at C5.

Note: Pay attention to distinguish between positive and negative. The Longer pin is positive pole.

Install 2pcs Red 2Bit Digital Tube at LED1,LED2.

Pay attention to installation direction.

Install 1pcs DIP-28 IC STC15W404AS at U2.There is a mark(notch) on one end of the IC and there is a mark(curved silk screen printing) 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

Connect 2pcs wire from 8ohm 0.5W Speaker to LS1 on PCB. The speaker does not need to distinguish between positive and negative, so the wire color is free to connect.

Connect 9V Battery Socket to PCB on ‘+’ and ‘-’. Red is positive pole to ‘+’.

Use a plastic bag to cover the speaker to avoid that the metal on the surface of the speaker directly touches the PCB pad, which may cause a short circuit.

Place speaker on case and fix PCB on case by 1pcs 1.7mm Self-tapping screw.

Install 1pcs 9V 6F22 battery.

Note:Users need to bring your own battery which not include in package.

Place 4pcs Button on LED. Just need place and no need to fix for now.

Install another case which also can fix buttons.

Press ‘START’ button to game and exercising your memory.
