Continue by wiring the front panel parts as shown in Fig 3. Notice that Individual
solder lugs are identified by part number and lug number. For example, S1-2
means the lug labeled “2” of the switch S1.
( ) Use a piece of excess resistor lead to connect S2-6 to S2-3. Solder the
connection at S2-3 but a second wire will connect
to S2-6 later and both wires soldered at that time.
In the following steps, connect wires from the
circuit board to front panel parts as listed.
Solder each connection as it is made.

( ) Connect and solder the free RED wire from one of the battery clips to S2-5.
( ) Connect and solder the free BLACK wire from the other battery clip to S2-2.
THE FRONT PANEL MAY NOW BE BOLTED TO THE CIRCUIT BOARD AS
FOLLOWS:
( ) Attach the two "L" brackets to the front panel by passing a 4-40 X 1/4"
machine screw through the holes in the panel and the unthreaded holes in the
"L" brackets. Secure each machine screw with a #4 hex nut. Do not fully tighten
until the front panel is aligned and attached.
( ) Fasten the front panel to the circuit board by passing a 4-40 X 1/4" machine
screw through the corner holes in the circuit board from the solder side and
into the threaded holes in the brackets. Tighten all screws.
( ) Mount the four rubber feet by peeling the protective backing and adhering
them to the corners of the bottom of the circuit board. See figure 2.

Note:
Be careful when
soldering the wires to the
switch. Too much heat
can soften the body of
the part causing the
solder lugs to shift
position. If you are using
a 30W or less soldering
iron there is little danger,
but higher power irons
should not be left on the
lugs too long.
