424. Convenient Features Checking Energy-Saving Effect [CARBON METER]This feature will show energy-saving effect in terms of CO2 emission reduction (kg) when the projector’s [ECO MODE]is set to [ON]. 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 78)The [CARBON SAVINGS-SESSION] message shows the amount of CO2 emission reduction between the time ofchanging to ECO 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 as shown below is used to calculate the amount of CO2 emission reduction.Amount of CO2 emission reduction = Power consumption in OFF for ECO MODE – Power consumption in ON for ECO MODE xCO2 conversion factor.** Calculation for amount of CO2 emission reduction is based on an OECD publication “CO2 Emissions from Fuel Combustion,2008 Edition”.• This formula will not apply to the power consumption which is not affected by whether [ECO MODE] is turned on or off.
