scanner mode, or with Bluetooth devices, other than the 2020 base.

Unlinking the Image Scanner

If the base has an image scanner linked to it, that image scanner must be
unlinked before a new image scanner can be linked. Once the previous image
scanner is unlinked, it will no longer communicate with the base. To unlink an
image scanner from the base, scan the Unlink Image Scanner bar code below.

Single Image Scanner Operation

There are two link modes to accommodate different applications: Locked Link
Mode and Open Link Mode. Scan the appropriate bar codes included in the
Open Link and Locked Link Mode explanations that follow to switch from one
mode to another. Default = Locked Link Mode .
