Use three screws to attach the back assembly to the C3765. Use the M4
x 40mm screw for the top hole and the M3 x 40mm screw for the lower
hole. These two screws use the two holes from which screws were
removed in the previous step. Use the M3 x 10mm screw to attach the
back assembly to the base CACStar assembly as shown below.
Turn on the C3765. Refer to the CACStar User’s Guide for
configuration.
