Focus Lock/Unlock
You must perform the Focus Lock procedure to save the mechanical focus position to
memory. If the mechanical focus position is changed by more than the allowed tolerance of
the value in memory, a diagnostic alarm will be sent to the display.
1. Enter the Focus Lock function by holding the Mode push button pressed until the FOCUS
LOCK LED is on.
2. Release the button to enter the Focus Lock function.
Once entered, the scanner automatically performs the Lock (saving) or Unlock procedure
depending on the previous state of the Locked Position parameter.
