98 - Terminology
A lamp cooling procedure continues to operate even after the power supply
has been switched off and the lamp extinguished. The cooling fan will begin
to operate when the lamp is entinguished, and button operations will not
longer be possible. This period is known as the cooling down period. The
amount of time required for the cooling down procedure will differ in accor-
dance with the surrounding temperature.
By strengthening or weakening the tone of the colors, it is possible to project
characters and pictures more clearly and attain a softer tint. This is known as
contrast adjustment.
Refers to the simultaneous duplicate projection of images with the use of mul-
tiple projectors in order to increase projection image brightness.
A threft-proof cable (available on the open market) is passed through the
holes on the projector case to secure it to a desk or column. These holes sup-
port the Micro-Saver Security System manufactuered by Kensington Inc. The

Outputs computer signals at a pre-determined frequency. The image will not
be projected clearly unless this frequency is aligned with the frequency of the
projector. Aligning the signal phasing is known as synchronization. Projected
images will be subject to distrubance, blurring and horizontal noise if not syn-
chronized.
