4. 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 [CARBON METER]. There are two messages: [TOTAL CARBON SAVINGS] and [CARBON SAVINGS-SESSION]. The [TOTAL CARBON SAVINGS] message shows the total amount of CO2 emission reduction from the time of shipment up to now. You can check the information on [USAGE TIME] from [INFO.] of the menu. (→ page 62) The [CARBON SAVINGS-SESSION] message shows the amount of CO2 emission reduction between the time of changing to ECO MODE immediately after the time of power-on and the time of power-off. The [CARBON SAVINGSSESSION] 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 x CO2 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. 30

4. Convenient Features
Checking Energy-Saving Effect [CARBON METER]
This feature will show energy-saving effect in terms of CO
2
emission reduction (kg) when the projector’s [ECO MODE]
is set to [ON]. This feature is called [CARBON METER].
There are two messages: [TOTAL CARBON SAVINGS] and [CARBON SAVINGS-SESSION]. The [TOTAL CARBON
SAVINGS] message shows the total amount of CO
2
emission reduction from the time of shipment up to now. You can
check the information on [USAGE TIME] from [INFO.] of the menu. (

)
The [CARBON SAVINGS-SESSION] message shows the amount of CO
2
emission reduction between the time of
changing 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 CO
2
emission reduction.
Amount of CO
2
emission reduction = Power consumption in OFF for ECO MODE – Power consumption in ON for ECO MODE x
CO
2
conversion factor.*
* Calculation for amount of CO
2
emission reduction is based on an OECD publication “CO
2
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.
