Note
The display positions that are set with [Display position] are cleared when the power supply to the Touch Finder is
turned OFF.
However, if the Sensor status is changed (by changing from Setup Mode to Run Mode), the current settings for [Dis-
play position] are saved in the Touch Finder. Therefore, the next time the same Sensors are connected, they will be
displayed in the same positions.
If a previously connected Sensor is not detected, either the display position will be blank, or if [Auto sensor detection]
is set to [ON], the Touch Finder will display another Sensor that it has detected.
If a previously connected Sensor is then detected by the Touch Finder, it will display the image from it in the previous
display position.
