293. Convenient FeaturesNOTE:• 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 blue. Thelamp 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] willautomatically 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] modeto protect the projector. When the projector is in [ECO1] mode, the picture brightness decreases. When the projector comes backto 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 istoo high.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] or [ECO1]. 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 101)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 AUTO ECO/ECO1 forECO MODE) × CO2 conversion factor.* When the image is turned off with the AV-MUTE button or with the lens cover closed, theamount 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, 2008Edition”.• 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.
