project. This mode is used when replacing or reinstalling the operating
system. Contact Maple Systems for more information.
Normal Operation: All DIP switches must be in the OFF position for
normal operation.
Fusing Requirements
If the display does not come on within two seconds of power up, remove
power. An internal fuse will prevent damage if the polarity of the DC
power is incorrect. Check wiring to insure proper connections and try to
power up again.
