The earlier data/manual is wrong for the +5V supply
(I changed LCD suppliers after the manual was written for the
prototype).
Backlight is 'BRIGHT' = 175ma of +5V
Backlight is 'NORMAL'
= 100ma of +5V
Backlight is off = 20ma of +5V
The manual is
....errr....fubar.
Also note, the '650 needs *all 3
supplies*.
