Note 3
Note 1: In order to satisfy the quality of B/L, no matter the type of inverter, the output lamp current must be between Min. and Max. to avoid abnormal dis-
play image caused by B/L.
Note 2: The waveform of lamp driving voltage should be as closed to a perfect sine wave as possible.
Note 3: The Max. of starting voltage means the minimum voltage of inverter to turn on the CCFl and it should be applied to the lamp for more than 1 sec-
ond to start up. Otherwise the lamp may not be turned on.
