3. Convenient Features
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],
[NORMAL],
or
[ECO].
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/
ARE
YOU
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/NORMAL/ECO for
ECO MODE) × CO
2
conversion factor.* When the image is turned off with the AV-MUTE button, 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.
