User manual

This manual describes the essential parts of the MR compatible camera with vario lens and
illustrates its operation.

1. Intended use

The MR compatible camera is designed to record video images of subjects in a MR scanner from a
distance. It can be used in a distance of about 1 m from the scanner entrance (depending on the
scanner's type and field strength). The correct orientation of the cables, the correct installation of
the filter box, and the correct grounding should be checked before the application. Respective
descriptions can be found in this user manual.
