Procedure of assembly wiring (7/13)
Mount the Light Emitting Diode D3(red)
The light emitting diode(LED) has polarity.
The long lead is a anode side( connect to plus voltage ) in the case of a new article. If you don't understand the polarity, see the page 'Light Emitting Diode'.
Mount D3 to 5F(anode side) and 6F(cathode side) from parts side.
Mount the LED, providing about 5-mm distance from printed board.
Solder the lead of D3 and R4 at 5F together.
Cut the lead of D3 at 5F.
Bend the lead of D3 of 6F with confirmation of it's hight to 7F, and bend more to 8F and 9F, and cut it at 9F.
Solder the lead of D3 and TR1 at 9F together.
Solder at 5E, 6F, 7F and 8F to the turn.
Mount the transistor TR2
Mount the transistor TR2 that flat face(name is printed) toward 9L, and the center lead(collector) to 9J, lead of emitter to 10K and the lead of base to 8K.
If you don't understand, see 'Component lead of the transistor'.
Mount the transistor, providing about 5-mm distance from printed board.
Bend the lead of 9J toward 9I, 8K toward to 7K and 10K toward to 11K each to prevent it fall.
Solder the lead of TR2 and R5 at 8K. (The hight of TR2 is fixed)
Adjusted TR2 vertically with printed board.
Cut the lead of TR2 at 8K.
Cut and leave about 0.5 mm the lead of 9J of TR2 that is bended toward 9I so as not to contact with surrounding land.
Cut and leave about 0.5 mm the lead of 10K of TR2 that is bended toward 11K so as not to contact with surrounding land.
