Technical information

Front Panel Control

• Upper & base lighting

• Positive/Negative toggle

• Color/B&W Selection

Upper & Base lighting buttons

• A press of a button will turn on/off the desired lamp.

• Only one lighting source can be “on” at the same time. (e.g. If the

upper lamps are on when the base button is pressed, they will

toggle off automatically prior to base illumination.)

• When using transparencies, film, etc. be sure to use the lower

lamp so that proper illumination will occur.

• The lamps are flourescent and will require a second or so to

power on after pressing either button.

Positive/Negative toggle

• This feature will permit the display of a film negative as though it

were a photograph or slide.

• When using this function, please allow a member of the court

staff to assist in fine tuning your negative’s appearance.

• Note that this button toggles between positive and negative mode

when pressed

• Also, the base lamp will not automatically come on when the

positive/negative button is pressed.

Color/B&W toggles between the display of color and black & white.

This function is rarely needed. The default mode is color.

Note: These four buttons each contain an arrow. The arrows are used for inter-

nal configuration of the system and have no significance during courtroom op-

eration. Ignore them.
