3. Convenient Features NOTE: • The [ECO MODE] can be changed by using the menu. Select [SETUP] → [GENERAL] → [ECO MODE]. • The lamp life remaining and lamp hours used can be checked in [USAGE TIME]. Select [INFO.] →[USAGE TIME]. • The projector is always in [ECO1]* for 90 seconds after the lamp is turned on and while the POWER indicator is blinking green. The lamp condition will not be affected even when [ECO MODE] is changed. • After a lapse of 1 minute from when the projector displays no-signal guidance, a blue, black or logo screen, [ECO MODE] will automatically switch to [ECO1]*. The projector will return to the [OFF] once a signal is accepted. • If the projector is overheated in [OFF] mode, there may be a case where the [ECO MODE] automatically changes to [ECO1]* mode to protect the projector. When the projector is in [ECO1]* mode, the picture brightness decreases. When the projector comes back to normal temperature, the [ECO MODE] returns to [OFF] mode. Thermometer symbol [ ] indicates the [ECO MODE] is automatically set to [ECO1]* mode because the internal temperature is too high. * [ECO2] on M300X and M260X only 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 [AUTO ECO], [ECO1], or [ECO2]. This feature is called as [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 88) 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 AUTO ECO/ECO1/ECO2 for ECO MODE) × CO2 conversion factor.* When the image is turned off with the AV MUTE button or with the lens cover closed, the amount of CO2 emmission reduction will also increase. * 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 [ECO MODE] is turned on or off. 27

• If the projector is overheated in [OFF] mode, there may be a case where the [ECO MODE] automatically changes to [ECO1]* mode
to protect the projector. When the projector is in [ECO1]* mode, the picture brightness decreases. When the projector comes
back to normal temperature, the [ECO MODE] returns to [OFF] mode.
Thermometer symbol [

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 [AUTO ECO], [ECO1], or [ECO2].This feature is called as [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/ AREYOU 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 AUTO ECO/ECO1/ECO2
for ECO MODE) × CO
2
conversion factor.* When the image is turned off with the AV MUTE button or with the lens cover closed,
the amount of CO
2
emmission reduction will also increase.
* Calculation for amount of CO
2
emission reduction is based on an OECD publication “CO
2
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.
