Main Functions

Tabletop projection
This projector can project images on a tabletop.
Image eco function
The projector switches the lamp power automatically by detecting the brightness of the image
signals. This function is useful for energy saving.

The projector starts projection automatically if the image signals are input even while in standby.
Auto keystone function
The projector automatically adjusts the shape of the projected image according to the angle at
which the projector is positioned.
AV Mute/Freeze
Pressing the [AV Mute] button mutes the sound and blanks the screen. Pressing the [Freeze] button
freezes the image temporarily.

Pressing the [Magnify] button enlarges the projected image. Pressing the [Zoom] button reduces the
projected image.
Presentation timer function
Pressing the [Timer] button displays the countdown timer on the projection screen. You can check
the elapsed time on the projection screen.
Wall color mode
You can adjust the hue of the image in accordance with the color of the wall on which it is
projected.
Password setting/Key lock
You can specify a password for the projector to limit the people that can use it. The buttons on the
control panel can be disabled with the key lock setting to prevent misoperation.
Administrator authentication
Enable administrator authentication so that only the administrator can change the security settings.
This improves the security of the projector because general users cannot change the settings.
