413. Convenient FeaturesChecking Energy-Saving Effect [CARBON METER]This feature will show energy-saving effect in terms of CO2 emission reduction (kg) when the projector’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 CARBONSAVINGS] message shows the total amount of CO2 emission reduction from the time of shipment up to now. You cancheck the information on [USAGE TIME] from [INFO.] of the menu. (→ page 139)The [CARBON SAVINGS-SESSION] message shows the amount of CO2 emission reduction between the time ofchanging 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 CO2 emission reduction. Amount of CO2 emission reduction = (Powerconsumption in [NORMAL] LIGHT MODE – Power consumption in current setting) × CO2 conversion factor.* When an energy-saving LIGHT MODE is selected, or the Lens Shutter is used, there will be a further reduction in CO2 emission.* Calculation for amount of CO2 emission reduction is based on an OECD publication “CO2 Emissions from Fuel Combustion,2008 Edition”.• The [TOTAL CARBON SAVINGS] is calculated based on savings recorded in 15 minutes intervals.• This formula will not apply to the power consumption which is not affected by whether [LIGHT MODE] is turned on or off.
