Overview ¶ 

This section provides troubleshooting help, also found in the Welch Allyn Connex® Vital Signs Monitor 6000 Series Service Manual starting on page 29.

Symptoms and solutions: These tables list symptoms you might observe, list possible causes, and suggest actions that may eliminate the problem.

Technical alarm messages: These tables list messages generated by the device software when a problem is detected. The tables explain possible causes and suggest actions that can resolve the problem. 
These tables can help you diagnose and fix a problem. They do not replace basic troubleshooting skills. You must still trace the source of the problem to the board or module level to decide the best course of action. Welch Allyn does not support component-level repair to the board or module. For available replacement parts, see “Field Replaceable Units.” 
WARNING Do not perform troubleshooting on a device that is emitting smoke or exhibits other signs of excessive overheating. Disconnect the device from AC power and call Welch Allyn Technical Support immediately. 
CAUTION Replace parts, components, or accessories only with parts supplied or approved by Welch Allyn. The use of any other parts can lead to inferior device performance and will void the product warranty.
