The following three Eco Mode settings are available to specify whether priority should be given to 
low-power, low-noise operation or to projection brightness.
Important!zWhile “On (Auto)” is selected as the Eco Mode setting, make sure that the brightness sensor 
on the top of the projector is not blocked by anything.
zThe local environment and setup conditions affect the brightness sensor, so operation when 
“On (Auto)” is selected for the Eco Mode depends on these factors.
To select the Eco Mode
1.Press the [ECO] key.
zThis causes “Eco Mode” window to appear on the projection screen.
2.Use the [W] and [X] keys to select the setting you want.
zIf you select “On (Manual)” here, go to step 3. If you select another setting, jump to step 4.
3.Perform the following steps to adjust the “Eco Level” (the balance between 
low-power, quiet operation and projection brightness).
4.To hide the window, press the [ESC] key.
Important!The “On (Auto)” setting cannot be selected for the Eco Mode while “Rear” is selected for “Screen 
Settings
J Projection Mode” (page 37) on the setup menu. If the “Projection Mode” setting is 
changed to “Rear” while “On (Auto)” is selected for the Eco Mode setting, the Eco Mode setting 
will automatically change to “On (Manual)”.
Eco Mode (Power Saving, Low Noise)
On (Auto): A brightness sensor on the top of the projector senses surrounding light, and 
automatically adjusts projection brightness and color accordingly. Brightness is 
reduced for darker surroundings, which saves power and reduces operation noise.
On (Manual): Enables manual adjustment to balance the needs of low-power, quiet operation and 
projection brightness.
Off: Give top priority to projection brightness.
1Press the [T] key to move the highlighting to the Eco Level.
2Use the [W] and [X] keys to adjust the Eco Level to the setting you want.
Fewer   marks gives higher priority to projection brightness. A greater number gives high 
priority to low-power, quiet operation. 
						

							24
NotezWhile “Off” is selected for the Eco Mode setting, you also can specify whether brightness or 
color should be given emphasis. For details, see “Eco Off Mode” (page 34) under “Image 
Adjustment 1 Main Menu”.

Basic Setup Menu Example
The procedure below shows how to configure the following three settings:
zImage Adjustment 1 J Contrast
zImage Adjustment 1 J Color Mode
zInput Settings J Signal Name Indicator
NotezThe setup menu items that you can change depend on whether or not an image signal is being 
input to the projector, and on the currently selected input source. Perform the procedure 
below after starting projection of an image from an input source.
zThis example covers basic steps only. For more detailed information, see “Setup Menu 
Contents” on page 33.
To configure the “Image Adjustment 1J Contrast” setting
1.Press the [MENU] key to display the setup menu.
2.“Image Adjustment 1” is initially selected on the main menu, so simply press the 
[ENTER] key.
3.Use the [T] key to select “Contrast”.
4.Use the [W] (lighter) and [X] (darker) keys to adjust contrast. 
						

							27

6.Press the [ENTER] key.
zThis displays the color mode menu.
7.Use the [T] and [S] keys to select the color mode you want, and then press the

Direct Power On
You can configure the projector so it powers up automatically as soon as you plug it into a power 
source. With this “Direct Power On” feature, you do not even need to press the [P] (Power) key. To 
enable Direct Power On, display the setup menu, and then change the “Direct Power On” setting to 
“On”.
Important!When you have Direct Power On enabled, do not leave the projector plugged into an electrical 
outlet while it is turned off. If you do, there is the chance that it (and the light source unit) might 
turn on automatically when power is restored after being cut off by a power outage, tripping of a 
breaker, etc.
NotezDirect Power On causes the projector to turn on automatically as soon as it is plugged into a 
power outlet. This greatly reduces the amount of time it takes until you are ready to start 
projecting. Note, however, that the actual startup sequence (Standby StateJ Power OnJ 
Projection Starts) that the projector performs is the same, regardless of whether Direct Power 
On is enabled or disabled. The only difference is what triggers the sequence (plugging in or 
pressing the [P] (Power) key).
zFor details about configuring the Direct Power On setting, see “Direct Power On” (page 39) 
under “Option Settings 1 Main Menu”.

The password feature lets you keep unauthorized individuals from using the projector. You can specify 
whether password input is required whenever you turn on the projector, and you can specify and 
change the password as required. Use the setup menu “Option Settings 1J Power On Password” 
setting to configure power on password settings.
Inputting a Password
The password of your projector is not really a “word” made up of letters, but rather a sequence of 
remote controller key inputs. The following is the 8-key sequence that represents the initial factory 
default password.
Using the Password Feature
Note the following precautions whenever you use the password feature.
zThe password feature protects against unauthorized use of the projector. Note that it is not an 
anti-theft measure.
zYou will need to enter the initial factory default password the first time you use the projector after 
turning on the password feature. Change the initial factory default password to a different one of 
your choice as soon as possible after turning on the password feature.
zRemember that password operations are always performed using the remote controller, so you 
should take care not to lose or misplace the remote controller.
zAlso note that you will not be able to input the password if the remote controller batteries are dead. 
Replace the remote control batteries as soon as possible after it starts to go low.
If you forget your password...
You will not be able to use the projector if you forget the password for some reason. If you forget the 
password, you will need to bring the following two items to your CASIO distributor to have the 
password cleared. Note that you will be charged to have the password cleared.
Note that your CASIO distributor will not be able to clear the password of your projector unless you 
bring both of the items listed above.
Also, keep the projector’s warranty in a safe place.
Important!Having your password cleared using the procedure described above will return all of the settings 
of your projector, except for the Light Time, to their initial factory defaults.
