(EMP-74/54 only)

Brightness Control

The following six preset colour modes are provided so that you can easily obtain the optimum images simply by selecting the image quality. In addition, if projecting onto blackboards rather than projection screens in places such as schools, you can select the "Blackboard" setting to allow images to be projected in their natural tints. Troublesome colour adjustments can thus be avoided.

• Blackboard

The brightness of the lamp can be set to one of two settings. If projecting images in a dark room or onto a small screen and the images are too bright, change the setting to "Low". In addition, when the setting is changed to "Low", the amount of power consumed and noise produced are reduced and the operating life of the lamp can be extended.

• Reduction in power consumption of approximately 20%

• Reduction in operating noise of approximately 10%

• Approximately 1.5 times longer lamp life

p.61

Automatic keystone correction function

The vertical angle of the projector is detected, so that any vertical keystone distortion in the projected images can be automatically corrected.

Features of the Projector

Compact and lightweight while producing beautiful, crisp images

The projector has a compact body with a footprint the size of an A4 page (24 (D) × 31.5 (W)

× 8.7 (H) cm (9.45 (D) ×

12.4 (W) × 3.43 (H) in.) and is light in weight (approximately 2.9 kg. (6.4 lbs)), making it easy to carry. Clear and attractive images can be obtained even in bright locations.

Easy to Operate

The accessory remote control can be used for operations such as pausing projection (see "Freeze" on an image (see "E-Zoom" on used to move the pointer around on th (see "Wireless Mouse Function" on

p.47) and zooming in on important areas of

function, you can use the remote control to scroll back and forth through pages when projecting a PowerPoint presentation.

Password protect function assists administration and theft prevention

If the password Protect function is em

ployed, a password can be used to limit operation of the projector and changing of settings. This means that the projector cannot be used if it is taken without authorisation, and thus serves as a theft-prevention feature.

Command List

When a power ON command is sent to the projector, the power for the projector turns on. When the projector is in a command ready state, it returns the "3Ah" (:) code. Furthermore, when command processing is complete, the projector also returns a ":" code. The ":" code status can be used to determine whether the projector is ready or busy. If command processing terminates with an error, an error message is output and then the ":" code is sent.
