The Diagnostic menu contains items for controlling the operating behavior
of Alignment and the Alignment reporting capabilities.
Visible Align

Align Log…
Invokes Notepad with the Alignment Log loaded. The log can be
viewed or saved to an external media or drive. Notepad can be closed
without a mouse or external keyboard by pressing ALT front-panel
key, then arrow down to highlight Exit, then press Enter.
Align Log Mode
The Alignment System places information about the last alignment
performed into a log. The log can be configured to operate in clear or
append mode. In clear mode the log only contains information on the
last alignment performed; the log is cleared with each alignment
performed. In append mode each new alignment appends to the log.
In append mode, care must be taken by the operator to not allow the
log to grow to a size so large as to inhibit system operation.
