FIGURE 35 - SETUP SCREEN
This screen is the top level of the general configura-
tion parameters. It allows programming of the time and
date, along with specifications as to how the time will
be displayed (12 or 24 hour format). In addition, the

Microboard Program Jumpers and Program Switches
is displayed. A qualified Service Technician, following
