Does anyone know of a thrid party vendor that repairs and calibrates Critlines? Thanks

Wish I did $600.00 per machine is not cheap.

What maintenance is required on Critlines? All I see in the manual that is posted on line is the verification test that has to be performed every thirty days. They mention an annual procedure that has to be done by "in-house biomedical staff" but they don't say what that entails. Is that what is costing $600.00, and does the unit have to be sent back to Salt Lake? Tell us more about your experience with these. I see that they make sure to tell you about proper procedure and solutions for cleaning the sensor head, have those been a problem with these?
