*3) Lamp frequency of inverter may produce interferenc e with horizontal synchronous frequency,
and this may cause horizontal beat on the display. Therefore, please adjust lamp frequency, and
keep inverter as far from module as possible or use electronic shielding between inverter and
module to avoid the interference.

*4) Lamp life time is defined as the time either when the brightness becomes 50% of the initial
value, or when the starting lamp voltage does not meet the value specified in this ta ble.
*5) The life time of the backlight depends on the ambient temperature. The life time will decrease
under low/high temperature.
