Preventive Maintenance General Information
1-6 MS278XB OM
1-3 Preventive Maintenance
Routine maintenance that can be performed by the operator consists of cleaning the data display, protecting
the operating system, and replacing a defective line fuse.
Cleaning the Touch Screen
The touch screen is protected by a plastic display filter. To clean the display filter, dampen a soft cloth with a
mild soap and water solution, or a commercial window cleaner. Do not use abrasive cleaners, tissues, or paper
towels that can scratch the plastic surface. Gently wipe the display filter to clean.
Operating System Integrity
The Microsoft Windows XP operating system is configured for optimum signal analysis performance when it
leaves the factory. To maintain the system’s operating integrity, follow proper Windows shutdown procedures
and do NOT modify the operating system settings or registry, hard drive partitions, or Anritsu user accounts.
Antivirus Protection
Signature is compatible with McAfee® VirusScan® Enterprise version 8.0.0. Signature has also been
tested with most common antivirus software, but stability is not guaranteed with all antivirus software.
Anritsu recommends that antivirus software be installed when the instrument is connected to a
network/Internet. The user assumes the responsibility to provide antivirus software as this is not
supplied with the instrument.
Windows Updates
Anritsu tests Signature with the latest Microsoft security updates as they become available; however,
not all Microsoft updates are compatible with Signature and may affect the performance of the analyzer,
if installed. Before connecting Signature to the Internet, consult Anritsu customer service for procedures
on how to safeguard the instrument from undesired conditions that could result from Windows
vulnerabilities.
