Should be an easy question.
Never used a tesa 300 before.(or any of the new systems for that matter)
When you turn the unit on (in the back) does the lamp automatically come on, or is there an icon in pcdmis that you have to click to make it come on??
You can switch from "cad" to "live" and the screen is just black. no light comes on.
How often do the bulbs need replacing?
This is brand new - just has not been used for about a year.
