7.2.3 Changing the Joystick TV Angle
In TV mode (chamberscope), it can occur that dual joystick and stage seem to move to opposite
directions. This is because the selected CCD camera is installed at a certain angle relative to the
stage. Thus, the camera shows a side-inverted view. To remedy this, you need to change the joy-
stick TV angle setting in the software.
Info
If you are working with two CCD cameras: The joystick TV angle can only be set for one CCD
camera. When selecting the other CCD camera, you have to change the setting.
CAUTION
Moving the specimen stage
Fingers can be trapped by the moving specimen stage.

Always close the chamber door before moving the specimen stage.

To remove parts fallen into or near to the stage use a tool (e.g. tweezers) instead of your
fingers.
