5. MAINTENANCE PROCEDURES
5.1 Introduction
This section provides the procedures required for accomplishing periodic and incidental maintenance activities. This
section is divided into three parts: performance check procedures, other maintenance procedures, and special
maintenance procedures.
5.2 Performance Check Procedures
Performance checks are accomplished using the built-in test equipment capabilities of the Marker Beacon. These
procedures do not require the use of external test equipment. The procedures can be performed at the Marker Beacon site
or from a physically separated site through the use of the Remote Maintenance Monitoring (RMM) capabilities.
5.2.1 Equipment Sign-On
Sign-on and procedures for operation of the equipment are available in Section Error! Reference source not found..
5.2.2 Perform Time Update
This procedure updates the Marker Beacon time indication.
Note: The RCSU will update time and date on a periodic basis. If the Marker Beacon is connected to an RCSU this time
and date will be replaced with the RCSU time and date. It is suggested that time and date be set at the RCSU so that all ILS
equipment is updated consistently from the RCSU.
