【Note 6-8】available area
Please turn on the lamp with symmetrical (negative and positive) voltage and current wave
form. Don’t use the unsymmetrical voltage and current wave which have spike wave.
【Note 6-9】Lamp frequency may produce interference with horizontal synchronous frequency,
and this may cause beat on the display. Therefore lamp frequency shall be detached
as much as possible from the horizontal synchronous frequency and from the
harmonics of horizontal synchronous to avoid interference.
【Note 6-10】The open output voltage of the inverter shall be maintained for more than 1s;
otherwise the lamp may not be turned on.
