Focus Lock/Unlock
You must perform the Focus Lock procedure to save the mechanical focus position to
memory. When Locked, 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. See
par. 2.3.1 for details.
NOTE: For Stand Alone or Master devices, the diagnostic alarm can also be
sent to any of the desired communication channels by selecting it in the
Diagnostic>Actions branch of the Genius configuration tool.
1. Enter the Focus Lock function by holding the X-PRESS 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.

Function
The procedure is as follows:
A) enter the Focus Lock function
B) wait until the "Focus locked at..."
message appears on the display
(indicating the focus position has
been saved to memory). The
following parameters are set:
Locked Position = your mechanical
setting
Focus Displacement (Alarm) = set
(default to display only)
The scanner will be reset at the end of the process. The LEDs turn off, the Display goes
blank and then the Ready LED will turn on indicating the scanner is ready.
