253. 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 [NORMAL] 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] willautomatically switch to [ECO]. The projector will return to its original setting 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 [NORMAL]mode to protect the projector. When the projector is in [NORMAL] mode, the picture brightness decreases. When the projectorcomes back to normal temperature, the [ECO MODE] returns to its original setting.Thermometer symbol [ ] indicates the [ECO MODE] is automatically set to [NORMAL] mode because the internal temperatureis too high.• Immediately after [ECO MODE] is changed from [ECO] to one of [OFF], [AUTO ECO], or [NORMAL], the lamp brightness maydecrease temporarily. This is not a malfunction.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], [NORMAL], or [ECO]. 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 81)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/NORMAL/ECO for ECO MODE) × CO2 conversion factor.* When the image is turned off with the AV-MUTE button, the amount of CO2 em-mission 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.
