ASSEMBLY INSTRUCTIONS

Identify and install the following parts as shown in Figure 4-2. After soldering each part, mark a check in the
box provided. Be sure that solder has not bridged to an adjacent pad.

Figure E

Stand diode on end. Mount
with band as shown on the top
legend.

Figure D

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. Note: If the
IC is already inserted into
the socket, do not attempt to
pull it out, as this will
damage the IC and socket.
Instead, solder the socket to
the PC board with the IC in it.
