Overview

The Elmo document camera is a visual presentation unit that can display a

variety of presentation materials.

Text, photos, slides, negatives, transparencies, drawings and three-dimensional

objects can be displayed in full color for local presentations and over the

Distance Learning network. The zoom lens can clearly display items as small as

the date on a dime.

The document camera has two built in lights to illuminate the objects being

presented, and a base light to illuminate slides and transparencies from beneath.

• The power cable should be

plugged securely into the unit.

• The power switch is located

on the left at the rear of the unit.

White Balance White balance can be set with the one-touch button.

The Presenter Camera automatically adjusts the color balance (AUTO mode). If,

however, this setting is lost, shoot the stage surface, and press the white balance

button [WHITE BALANCE] on the operation panel. The indicator lamp blinks and

then lights up, the mode is switched to the ONE-PUSH mode, and the white

balance is fixed.

When the white balance button [WHITE BALANCE] is pressed again, the

indicator lamp goes out, and the mode returns to the AUTO mode.

AUTO................. To set the white balance in the auto follow mode (initial setting).

ONE-PUSH ......... To set the push-set white balance. By pressing the button

[WHITE BALANCE], the white balance for the then color temperature is fixed.

Focus Allows you to manually fine tune the focus of the image displayed.

(It is also possible to adjust focus by turning the lens by hand.)
