5 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 CAR-
BON 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 “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 [ECO MODE] is turned on or off.
