10. Do not sterilize the Polaris Vicra Position Sensor as this may cause irreversible damage to its
components. Reliance on data provided by a damaged Position Sensor may lead to inaccurate
conclusions. If your application involves personal safety, these inaccurate conclusions increase
the possibility of personal injury.
11. Do not use the Position Sensor without inspecting it for cleanliness and damage both before and
during a procedure. Reliance on data provided by an unclean or damaged Position Sensor may
lead to inaccurate conclusions. If your application involves personal safety, inaccurate
conclusions increase the possibility of personal injury.
12. Do not use the Polaris Vicra System for absolute measurements; the system is designed for
relative measurements only. Treating measurements as absolute may result in an incorrect
interpretation of results. If your application involves personal safety, these incorrect
interpretations increase the possibility of personal injury.
13. Do not use a wireless tool whose design does not conform to the Polaris Vicra System's unique
geometry constraints. When a Polaris Vicra System attempts to track more than one wireless
tool in the measurement volume, these unique geometry constraints ensure that they are
distinguishable from each other. Reliance on data produced by two indistinguishable tools can
lead to inaccurate conclusions. If your application involves personal safety, these inaccurate
conclusions increase the possibility of personal injury.
14. Do not use a tool with a tip without first performing a pivot procedure to verify the tip offset.
Reliance on data produced by a tool with an inaccurate tip offset may lead to inaccurate
conclusions. If your application involves personal safety, these inaccurate conclusions increase
the possibility of personal injury.
15. Do not use markers without inspecting them for cleanliness and damage both before and during
a procedure. Reliance on data produced by unclean or damaged markers may lead to inaccurate
conclusions. If your application involves personal safety, inaccurate conclusions increase the
possibility of personal injury.
16. Do not obstruct the normal flow of air around the Position Sensor (for example, draping or
bagging the Position Sensor). Doing so will affect the Position Sensor's operational
environment, possibly beyond its recommended thresholds. Reliance on data provided by a
Position Sensor that is outside of recommended thresholds may lead to inaccurate conclusions.
If your application involves personal safety, inaccurate conclusions increase the possibility of
personal injury.
