Maintaining the SG20T
To keep your SG20T in good working order, you may need to upgrade
the SG20T firmware and clean the scanner window.
Upgrading the SG20T
You may need to upgrade the SG20T firmware if there is an update
that incorporates changes to a feature or adds functionality to the
scanner. When you upgrade your scanner the current settings are
erased and replaced with the default settings. The process of
upgrading the SG20T takes about 10 minutes to complete.
To upgrade the SG20T you need:
• An RS-232 or USB cable. For more information on cables, see
“Required Accessories” on page 6.
• Minimum PC operating system requirements are Microsoft®
Windows® XP with SP2 or Microsoft Windows 2000 with SP4 or
higher versions.
• EasySet version 5.6.5.1 (see “Configuring Your System with
EasySet” on page 31) or later.
• The firmware update file (.bin).
