Quick start & quick cool down
Eight seconds after turning on the power, the projector is ready to display PC or video images. Powering down, the fans stop 30 seconds
after turning off the power from the remote control or cabinet control panel. The projector can be stored immediately after powering down.
The main power for the projector can be turned off by either pressing the main power switch or by unplugging the power cable, even
during the cool down period after the projector is turned off.
Auto Vertical Keystone Correction adjusts the trapezoidal distortion to correct the projected image.
Wall Colour Correction for vivid images even without a screen
Without a screen, projected images are affected because of the colour of the wall or blackboard you are projecting on to. The built-in colour correction for projecting images on a coloured wall or blackboard in this projector means that the colour tones of the projected image is approximate to those that are projected on to a white screen. The following eight colour options are available : blackboard, blackboard (grey), light yellow, light green, light blue, sky blue, light rose, and pink.
