General Troubleshooting Guidelines
If the Valleylab LS10 generator malfunctions, check for obvious conditions that may have
caused the problem:
• Check the system for visible signs of physical damage.
• Make sure the fuse drawer is tightly closed.
• Verify that all cords are connected and attached properly.
• If the problem is still unclear, turn the generator off, wait a minute or two, then turn
it back on.
If the malfunction persists, the system may require service. Contact the institution's
biomedical-engineering department. Covidien Technical Service may be contacted in the
ways indicated.
