See figure 3-3. Insert the new micro-
processor IC (“BC” in the part number) in the empty
socket. Ensure that the notch on the new micropro-
cessor IC is facing the same direction as the old one
(toward the seven pod connector cables) and that all
IC pins are properly inserted in the socket—not bent
under.

Reassemble the lightbar.
3-3. SOFTWARE REVISION LABEL INSTALLATION.
In addition to the three microprocessors, labels
indicating the software type and revision are also
included. The labels are to be installed on the control
head, Interface/Relay Unit, and the lightbar.
After the microprocessors are installed as
described above, install the labels as follows:
A.
Place the label marked with a “CH” on the
control head housing near the modular jack.
B.
Place the label marked with a “BB” on the
bottom of the Interface/Relay Unit housing.
C.
Install the label marked with a “BC” inside
the dome of pod 1 (first pod on driver’s side). Place
the label near the rear of the metal motor support.
