given detailed instructions on how to
install and solder the first part on the
circuit board. Read and perform each
step carefully. Then use the same
procedure whenever you install
parts on the circuit board.

black-red) resistor by the body
as shown and bend the leads
straight down.

at the indicated location on the
circuit board. The &nd with [
color bands may be positioned
either way. : :
