AdminManager Tasks
• Use the Installation Wizard to:
• Set the Operation Band
• Use the Configuration & Maintenance panel to:
• Set Callback Number
• Set Contact Sense Properties
• Set System Parameters
• Perform System Test
During the System Test the system is out-of-service and no RF is being trans-
mitted. Choose a time of day to perform the System Test that will have the least
impact on the system.
