Maintenance, Cleaning and Disposal
This chapter provides information on maintenance and cleaning of the Dantec Keypoint G4 system. Natus Technical Support contact
information is provided at the end of this chapter.

Maintenance

Follow a regular schedule of maintenance and safety checks to keep the Keypoint G4 system in good working condition. Regular maintenance
performed by the user does not involve access to the interior of the system or components. If issues arise, contact Natus Technical Support per
contact information at the end of this chapter.
• Reboot the Keypoint G4 laptop or desktop on a weekly basis to optimize computer operation.
