Power Supply: Connect the power supply to terminals #7 and #8 as
shown above.
Display Adjust: Connect a short between terminals 5 and 6 as
shown. Shorting these terminals will cause the display to continuously
cycle through 6 levels of brightness. When the desired brightness level
is attained, remove the short. The selected brightness level is stored in
memory and will be maintained. To readjust brightness level, repeat the
above procedure.
NOTE: Recalibration is not required after an input change. If
desired, however, procedure is available from Technical Support.
