Figure E
Electrolytic capacitors have
polarity. Be sure to mount them
with the negative (–) lead
(marked on side) in the correct
hole.
Warning: If the capacitor is
connected with incorrect
polarity, it may heat up and
either leak or cause the
capacitor to explode.
Figure F
Thread the battery snap wires through the hole
in the PC board from the solder side as shown.
Solder the red wire to the (+) point and the
black wire to the (–) point on the PC board.
