Patient Registration
Warning
Make sure that all screws of the Reference Clamp Universal are tightly closed before
beginning registration.
Warning
Make sure that the Reference Clamp Universal is tightly attached to the head holder before
beginning registration. Any movement of the Reference Clamp Universal independent from
a movement of the patient’s head causes inaccuracy and is a hazard to the patient.
Warning
Do not unscrew any Reference Clamp Universal screws after registration. Only the fixation
nut can be unscrewed to exchange the Standard Cranial Reference Array.
