Disclaimers - Northern Digital Polaris Vicra User Manual

3. Always place the Position Sensor on a rigid support system. If not supported, the Position
Sensor may fall which will affect the calibration and damage the Position Sensor.
4. Use only 70% isopropanol and a lens cleaning solution formulated for multi-coated lenses (for
example, AR66) to clean the Position Sensor. Other fluids may cause damage to the illuminator
filters. Do not use any paper products for cleaning. Paper products may cause scratches on the
illuminator filters.

Disclaimers

1. Read the entire "Polaris Vicra User Guide" before attempting to operate the Polaris Vicra
System.
2. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
a) this device may not cause harmful interference, and
b) this device must accept any interference received, including interference that may cause
undesired operation.
See Section 12.6 on page 68 for further information.
3. The user must determine the suitability of the Polaris Vicra System for their own application.
4. The Underwriters Laboratories Inc. (UL) recognition of the Polaris Vicra System includes only
the Polaris Vicra Position Sensor, Host USB Converter and the APS APS49ES-24021/Hitron
HES49ES-24021 power adapter. This investigation does not include the use of any other power
adapter or source with the Polaris Vicra System. Any such configuration will require further
investigation. If the Polaris Vicra System is used in a medical application, the final end-use
configuration must be independently investigated to the IEC 60601 family of standards and all
applicable national differences.
5. This equipment has been investigated with regard to safety from electrical shock and fire
hazard. The inspection authority has not investigated other physiological effects.
6. The Polaris Vicra Position Sensor requires a thermal stabilization period in order to provide
reliable measurements. Up to 10 minutes are required for the optical components to reach
operating temperature from a cold-start at normal room temperature. Testing should be
conducted to determine the thermal stabilization time necessary specific to your application
requirements. NDI recommends that a reference tool be used with its systems whenever
possible, to ensure there is no drift in the measurement caused by time, settling and/or
temperature.
7. Northern Digital Inc. has not investigated the implications of incorporating the Polaris Vicra
Position Sensor with an automatic position device, or any other automated closed loop systems.
Using the Polaris Vicra System in such an application is solely the responsibility of the user.
8. Northern Digital Inc. has not fully validated the Polaris Vicra Position Sensor in an MRI
environment. If the Polaris Vicra Position Sensor is used in an MRI environment, the user is
responsible for determining the performance of the system, including accuracy, in an MRI
environment.
