HandHeld Entertainment Document Reader 4800dr - Manual (Page 31)

4800dr Barcode Guide 3 - 9
Decode Window
This feature defines an area or window within which a barcode must be placed in order to be decoded. Although the aimer
brackets are displayed over a wide area, you can define a smaller window for decoding barcodes. This will improve decode time.
Note that the barcode can only be decoded if it is entirely within the defined window.
Setting a decode window does not change where the illuminated aimer brackets appear, so the user may think the decode area
is larger than it is. A user should center the barcode under the illuminated crosshairs to insure a proper read.
The decode window is based on the percentage of the field of view. The 4800dr defaults to Decode Window On, Decode Window
X at 68%, and Decode Window Y at 60% (this emulates the decode area of our other imaging products).
If you want the decode window to use the full field of view, scan the Decode Window Off (Full FOV) barcode. (Note that this
slows decode time.)
To set a decode window, scan the Decode Window On barcode. Next set the percentage of the field of view for the window by
scanning the Decode Window X barcode and scanning up to 3 digits from the inside back cover this manual to set the
percentage of the field of view for the X setting. Scan the Decode Window Y barcode and scan the digits for the percentage of
the field of view for the Y setting. Scan Save.
