Checking Energy-Saving Effect [CARBON METER]
This feature will show energy-saving effect in terms of CO
jector's [LIGHT MODE] is set to either [ECO1] or [ECO2]. This feature is called as [CARBON METER].
There are two messages: [TOTAL CARBON SAVINGS] and [CARBON SAVINGS-SESSION]. The [TOTAL
CARBON SAVINGS] message shows the total amount of CO
shipment up to now. You can check the information on [USAGE TIME] from [INFO.] of the menu.
(→ page 156)
The [CARBON SAVINGS-SESSION] message shows the amount of CO
the time of changing to [LIGHT MODE] immediately after the time of power-on and the time of
power-off. The [CARBON SAVINGS-SESSION] message will be displayed in the [POWER OFF / ARE
YOU SURE ?] message at the time of power-off.
TIP:
• The formula shown below is used to calculate the amount of CO
consumption in [NORMAL] [REF. LIGHT MODE] – Power consumption in current setting) × CO

Edition".
• The [TOTAL CARBON SAVINGS] is calculated based on savings recorded in 15 minutes intervals.
• The power consumption when the projector is in standby mode is excluded from the calculation of the amount of CO
reduction.
