format is selected. Adjust the inter-
character delay symptom.
Increase the interscan code delay
setting. Adjust whether the F0

It may be necessary to try this in
both settings.
Enable the Caps Lock detect feature
of the scanner to detect whether the
PC is operating in Caps Lock.
Try operating the scanner in Alt

Check to make sure that the baud
rate and parity of the scanner and
the communication port match and

"RS232" data.

connected to the correct com port
on the host device.
Check that the scanner and the host
are configured for the same
interface parameters.
