6.Installation Steps (Please be patient):
Step 1: Install 2pcs 68Kohm Metal Film Resistor at R1,R2.
Step 2: Install 27pcs 10Kohm Metal Film Resistor at R3-R29.
Step 3: Install 2pcs TO-92 S9014 Transistor at Q1,Q2. The arc of the S9014 corresponds to the arc silk screen of the PCB.
Step 4: Install 2pcs 10uF Electrolytic Capacitor at C1,C2. Note: Pay attention to distinguish between positive and negative. The Longer pin is positive pole and connect to symbol ‘ + ’.
Step 5: 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:
5.1>.According to the length of the LED lead to distinguish. The longer pin is positive(anode) lead. The shorter pin is negative(cathode) lead.
5.2>.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.
5.3>.Identify by edge of plastic case. The negative(cathode) lead of the LED should be the pin nearest the flat on the plastic case.
5.4>.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)
5.5>.It is positive(anode) where the white mark “+” pointing to on PCB., Electronic Assembly Training parts
Step 6: Install 3pcs 3mm Green LED at D63,D64,D65. Note: The longer pin connect to square pad.
Step 7: Install 8pcs 3mm Red LED at D55-D62. Note: The longer pin connect to square pad.
Step 8: Install 72pcs 3mm Blue LED at D1-D54,D66-D83. Note: The longer pin connect to square pad.
Step 9: Install 1pcs 8.5*8.5mm Self-locking switch at S1.
Step 10: Install 1pcs 3.5mm DC Socket at P1.
Step 11: Install 4pcs M3+10mm Copper pillar and 4pcs M3+7mm Screw on PCB as bracket.
Step 12: Tear off the acrylic surface protective film.
Step 13: Install Acrylic bottom plate by 4pcs M3+7mm Screw.
Step 14: Install 4pcs side acrylic panels by M2+10mm Screw and M2 Nut.
Step 15: Install Acrylic top plate by M2+10mm Screw and M2 Nut.
