Unitech Electronics Co. Ltd. MS926BT ユーザーズマニュアル

 

Use Presentation Centering to narrow the scanner’s field of view when it is in 

the stand to make sure the scanner reads only those bar codes intended by 

the user. For instance, if multiple codes are placed closely together, 

Presentation Centering will insure that only the desired codes are read.     

To adjust centering when the scanner is hand-held, 

is not touched by a predefined window, it will not be decoded or output by the 

scanner. If Presentation Centering is turned on by scanning Presentation 

Centering On, the scanner only reads codes that pass through the centering 

window you specify using the Top of Presentation Centering Window, Bottom 

of Presentation Centering Window, Left, and Right of Presentation Centering 

Window bar codes. In the example below, the white box is the centering 

window.    The centering window has been set to 20% left, 30% right, 8% top, 

and 25% bottom.    Since Bar Code 1 passes through he centering window, it 

will be read. Bar Code 2 does not pass through the centering window, so it will 

not be read.
