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.
Some units have two optional, Auxiliary Lights to illuminate the objects being
presented.
BOCES DL classrooms are designed with sufficient ceiling lighting above
the teacher’s podium. Auxiliary Lighting is rarely necessary.
All units have a base light to illuminate slides, negatives and transparencies from
beneath.
Power Switch
•
Check to see that the power cable is plugged securely into the unit.
•
The power switch is located on the Back Panel to the left of the Pedestal
Arm.

Back Control Panel Adjustments
Input Selector
For Distance Learning the input selection should always be left
on INTERNAL. Press the round button above “INTERNAL”.
White Balance
In almost all cases,
leaving the White Balance on
AUTO will work best.
Manual White Balance adjustments can
be made, if necessary, by switching to
MANU and adjusting the red [ R ] and
the blue [ B ] levels with the button
above the coresponding letter.
If the switch has been moved
to MANU, it should be returned to AUTO.
POSI - NEGA Choose either a positive or negative image display. In some
cases changing to negative or positive can make printed material more readable.
It is also possible to display photographic negatives in true color (as if they were
positive transpariencies).
Color – B / W Choose either a COLOR or black and white B/W image
display. In some cases changing to COLOR or B/W can make an image more
readable.

Front Control Panel Adjustments
Lamp - Select
Power for the lamp or lamps is controled with the OFF – ON button at the left. If
your unit is equipped with the optional auxiliary lighting arms, they may be used
to Illuminate opaque materials on the STAGE.
The ceiling lighting in BOCES DL rooms should be sufficient for lighting opaque
materials.
The SELECT button is used to direct power to either the OPT. (optional auxiliary
lights) or the BASE lights.
BASE lighting is used for slides, photographic negatives and transparencies.
Some transparencies, however, may be more readable when illuminated from
above rather than from below.
Iris Adjustments
Iris adjustments will change the
exposure or brightness of the image.
In almost all cases, leaving the
IRIS adjustment in the automatic
position will work best.
Auto IRIS control is on when the knob
is left in the middle position. There is a
slight detent.
Manual IRIS adjustments can be made by turning the IRIS control knob.
If the switch has been moved away from the center position, it should
be returned to the center, AUTO position.

Focus
Focus adjustments must be made manually with the two FOCUS buttons.
Zoom
These controls increase or
decrease the image size
displayed.
T (for tele) will increase the
size of the image.
W (for wide) will decrease the
image size.
See important notes on font, format and image size in the
Presentation section of this manual.
Additional Magnification Range
Column Adjustment
By adjusting the column, you can lower the
camera head for very close work and
greater magnification.
For a wider view and greater coverage,
you can raise the column.
Adjustments are made by pressing
the latch on the side of the column and
sliding the column up or down.
Remember that you will have to adjust the
focus to accommodate the new column
height.
When you make adjustments, please consider that you can avoid confusion on
the part of other presenters if you will return the adjustments to their normal
settings.
