Abstract

A remote-controlled slide projector is proposed in which for interrupting a slide presentation the projection lamp and the blower can be de-energized by a standby command of the remote control device. To continue the slide presentation, blower and projection lamp can be re-energized by another command via the remote control device. In the standby mode, the electronic control circuit of the projector is continued to be supplied with power.
