Note (2) The voltage that must be larger than Vs should be applied to the lamp for more than 1 second
after startup. Otherwise, the lamp may not be turned on normally. It is the value output voltage of
NF circuit.
Note (3) The lamp frequency may produce interference with horizontal synchronization frequency from the
display, which might cause line flow on the display. In order to avoid interference, the lamp
frequency should be detached from the horizontal synchronization frequency and its harmonics as
