2.1Introduction

This chapter is divided into four basic sections: the Electrical Section, the Optical Section, the Electronic Section and the Miscellaneous Items. Each section gives a basic description of the components in the section and a description of the function of those components. This provides an overall view of the projector and its subsystems for a general understanding of how these systems contribute to the function of the projector.
