Q500 to ST10 Binding Verification.
The verification is not just "binding instructions". It is a verification of the MANY hidden clues in the binding process. The purpose is to identify abnormal conditions that are preventing a successful bind and to identify the exact point the binding process is failing. That information can assist in determining the best course to remedy the problem.
You will need to perform every step up to the point the verification does not match what you see. Do not skip any steps. Every step must be performed. Even the steps you have no doubt are already in the correct condition. After some preparation steps, the verification falls into a routine of directing an action, then verifying the correct response to the action. When you reach a verification step that does not match what you see, or if you are unsure if it matches, STOP. Report the step number back to the forum, and what you actually saw at that step. We can then go from there.
