Possible Solutions
The omni-line scan pattern does not
display when following the directions for
installing the host cable on

Check for loose cable connections.
Scan line(s) display, but bar code cannot
be read.

the host’s settings.
• For keyboard wedge, ensure scanner is programmed with the correct
country code and that the CAPS LOCK key is off.

programmed.
