The following parameters are set:• Locked Position = your mechanical setting• Focus Displacement (Alarm) = set (default to display only)If the Focus lock has already been set, this procedure can be used to Unlock the focus value.In this case control of the focus position is disabled.The scanner will restart at the end of the process.Reset Scanner to Factory DefaultIf it ever becomes necessary to reset the scanner to the factory default values, you canperform this procedure by holding the X-PRESS™ push button pressed while powering upthe scanner.
