Auto Sensing Mode-Automatic Detection Of Labels - Denso GT10B-SU User Manual

6.3 Auto Sensing Mode—Automatic Detection of Labels
In auto sensing mode, bringing a code label within the scan range of the reading window turns on the illumination LED
and starts the scanner reading the bar code. No trigger switch operation is required. Use this mode when the scanner is
stationary to a stand and a bar code label is moved.
The illumination LED comes on when you bring a bar code label within the designated range or move a bar code label
within the same range. The LED goes off when a bar code label is moved away from the range or stays within the range
without move for approx. 5 seconds.
The scanner offers a choice of three sensitivity levels for responding to bar codes. Switch to a higher sensitivity level if the
illumination LED will not come on when a bar code is brought into the range, for example.
Note: Even if you do not bring a bar code label within the scan range, the illumination LED may come on when the
ambient level of light changes or any shadows move within the scan range.
