Technical Bulletin 9: Software Update V 1.22 - Guardian R1000 Operation Manual

To: All Alexeter Guardian Reader System™ Customers
Subject: Guardian Reader Software Update (v 1.22)
Date: 18 January 2006
Some time ago, Alexeter identified an issue with the Guardian Reader's internal clock. The time
setting was "drifting" more than our engineers had initially anticipated. After being deployed for
several years, the Reader's clock might be "off" by almost an hour. Note that this time
discrepancy has no effect on Reader performance. It only affects the "time stamp", which
records the time each test is run.
Summary:
To address this issue, we are offering a software update that installs operating system version
1.22 on your Guardian Reader. Version 1.22 allows the user to reset the Guardian's clock. The
software also improves the reliability of the testing procedure, ensuring that expired test strips
cannot be inadvertently used. Alexeter customers may request this software update at no
charge, or download it from our website.
Recommendations:
1. We recommend that you run this update, installing operating system version 1.22. The
update software is available on Alexeter's website: www.alexeter.com. You can also
obtain a copy via email by sending a request to service@alexeter.com.
2. In order to install the software, you must have access to a computer with a DB-9 serial
port. The software cannot be loaded via USB or with USB to Serial adapters. You will
also need a serial cable to perform the update. If you cannot access such equipment,
Alexeter will update your Guardian Reader for a nominal fee.
3. Complete upgrade instructions are available in the document "Installing the Guardian
Software Update 1.2.2", available at Alexeter's website: www.alexeter.com.
