NEC NP-P350W, NP-P420X, NP-P350X Checking Energy-Saving Effect CARBON METER, Convenient Features

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] ([ECO2])* for 90 seconds after the lamp is turned on and while the POWER indicator is blinking blue. 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] ([ECO2])*. 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] ([ECO2])* mode to protect the projector. When the projector is in [ECO1] ([ECO2])* 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] ([ECO2])* mode because the internal tem- perature is too high.

* [ECO2] on P350X 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 101)

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 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/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.
