Crown RC5500:
RC5520-30 error 740

I am getting a sporadic error number 740. When it does this, it shuts down the side shift until you turn the key off and then back on. I have recalibrated it with no change. Any help would be greatly appreciated.

When calibrating the pot make sure to push the pot as far as possible. You can check the voltage in the analyzer menu A2.2.7 the voltage should be between 2v and 11v when using the pot. If it is outside that range replacing the pot should solve the issue.
