Section 4: Routine maintenance
This section provides instructions for performing routine maintenance on the XR12 transmitter. This
section includes the following topics:
• Scheduled maintenance
• Replacing air filters - see page 4-2
• Performing on-air checks - see page 4-3
• Replacing the control/display PWB battery - see page 4-3
• Inspecting lightning protection systems - see page 4-4
Scheduled maintenance
Scheduled maintenance consists of performing a visual inspection of the XR12 at scheduled intervals.
The recommended minimum time between scheduled maintenance visits is three months. Local
operating and environmental conditions may dictate more frequent visits, while in remote sites less
frequent visits may be acceptable. Experience and system reliability will determine the most practical
schedule for a specific installation.
Cleaning
At a minimum, follow the cleaning procedures listed below.
1. Inspect the air filter. If the air filter becomes damaged, it should be replaced as soon as
possible. See “Replacing air filters” on page 4-2 .
2. Clean the XR12 using a vacuum cleaner and a soft-bristle brush to remove loose dirt. Clean,
damp rags should be used to remove dirt that cannot be removed with a vacuum cleaner.
Never use compressed air to clean the XR12.
Note:
A site located in a dirty area using open-air cooling requires more extensive cleaning than a site
located in a clean area using closed-air cooling.
