Before Use
Warning
Use of Z-touch is strictly limited to medical personnel familiar with laser products.
Inappropriate handling of laser equipment is a hazard to patients and clinical staff.
Correct Instrument Handling
Warning
Handle the pointer with extreme care. Should the pointer tip become bent or deformed in
any way, report this to Brainlab support. Working with a damaged pointer tip will lead to
extreme inaccuracy during navigation.
Warning

camera.
Do not modify Z-touch.
