ASSEMBLE COMPONENTS TO THE PC BOARD
Note: C7 is not used in this kit.
Figure D
These capacitors are
polarized. Be sure to
mount them with the “+”
lead in the correct hole as
marked on the PC board.
Warning: If the capacitor
is connected with incorrect
polarity it may heat up and
either leak or cause the
capacitor to explode.
Figure B
Mount the device with the flat
side in the same direction as
shown on the PC board. Solder
and cut off the excess leads.
Figure C
Align the socket notch (if any)
with the notch marked on the
PC board.
Solder the socket to the PC
board. Insert the IC into the
socket with the notch as shown
below.
