Calculation of lamp hour
When the projector is in operation, the duration (by hours) of lamp usage is automatically calculated by the
Total (equivalent) lamp hour = hours used in Economic mode + hours used in normal mode
See "Economic Mode (Off)" on page 43 for more information on Economic mode.
The lamp hour in Economic mode is calculated as 2/3 of that in normal mode. That is, using the projector in Economic mode helps to extend the lamp hour by 1/3.
