Turn the VR12 on, and allow to warm up for at least one
minute.
Set the brightness POT on the VR12 to 3/4 maximum.
(NOTE: if a

intensity
to
burning the phosphor)
Set the MODE switch on
console to L mode.
Depress
preset.
Set all switches to ¢ 0 s.
(This will set up the program for the first display)
