Remote Control
The AP250 is operated by an intuitive remote control that
is divided into various sections for ease of use (see gure
5). When the power switch on the back of the instrument
is in the ON position, slides can be projected by simply
pushing any button. The Lamp ON / OFF button can
be used to turn the lamp off at anytime. Otherwise, the
AP250 lamp shuts off automatically after 10 minutes of
non-use.
