4. Convenient Features
Checking Energy-Saving Effect
This feature will show energy-saving effect in terms of CO
2
emission reduction (kg) when the projector’s [Lamp
mode] is set to [Quiet]. This feature is called as [Carbon meter].
There are two messages: [Total carbon savings] and [Carbon savings-Session]. The [Total carbon savings] mes-
sage 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 [Information] of the menu. See page
.
The  [Carbon  savings-Session]  message  shows  the  amount  of  CO
2
  emission  reduction  between  the  time  of 
changing  to  [Quiet]  mode  immediately  after  the  time  of  power-on  and  the  time  of  power-off.  The  [Carbon  sav-
ings-Session]  message  will  be  displayed  in  the  [Push  POWER  button  again  to  turn  off  power/  Carbon  savings-
Session/23.220(g-CO2)] 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 [Quiet] for [Lamp mode] – Power consumption in [Quiet] for Lamp 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 [Lamp mode] is set to [Quiet] or not.
