(Note 1) Please design your lamp driving circuit (inverter) according to the above specifications,

and inform Hitachi of it.

(Note 2) Starting discharge voltage is increased w hen LCM is operating at low er temperature.

Please check the characteristics of your inverter before applying to your set.

(Note 3) Average life time of CFL w ill be decreased w hen LCM is operating at low er temperature.

(Note 4) Under low er driving frequency of an inverter, a certain backlight system (CFL & CFL

reflection sheet) may generate a sound noise. Before designing the inverter, please

consider the driving frequency and the noise.

(Note 5) Under low er temperature, please check CFL characteristics on your inverter.
