PC BOARD ASSEMBLY
Identify and install the following parts as shown in Figure 6-15. After soldering each part, place a check in the
box provided.
C8 - .02µF Discap (.02 or 203)
C10 - 30pF Discap (30)
X - Resonator 3.58MHz
C11 - 30pF Discap (30)
C3 - 47µF Lytic Capacitor
(see Figure F)
Figure G
Insert the IC socket into the
PC board with the notch in
the direction shown on the
top legend.
Solder the IC
socket into place. Insert the
IC into the socket with the
notch in the same direction
as the notch on the socket.

Figure H
Identify the pulse/tone switch as
shown in Figure Ha. The pulse/tone
switch is mounted on the copper
side of the PC board. Insert the
switch tabs into the holes provided
and solder the three terminals as
shown in Figure Hb. Be sure that
the switch is perpendicular to the
PC board.
To anchor the switch in place,
grasp the switch tabs with your
pliers and give a 1/8 turn as shown
in Figure Hc.
