Focus Lock/Unlock
Once entered, the scanner automatically performs 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.
The procedure is as follows:
-
enter
the Focus Lock function.
-
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)
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 Default
If it ever becomes necessary to reset the scanner to the factory default values, you can
perform this procedure by holding the X-PRESS™ push button pressed while powering up
the scanner. At the end of the procedure (about 5-6 seconds), the Configuration and
Environmental parameters are reset, all LEDs blink simultaneously 3 times and the message
"Default Set" is shown on the display.
