Tell me a lot about your skill sets and instruments on hand, I can coach you most appropriately that way.

Is the system still running correctly or is OFF on this error code.

Tell me the blink pattern so I can confirm the 53 code.

We can go from there

About how old is the system?

Can you tell me a bit about its service history?
