SLR 5000 Series Maintenance and
Disassembly/Reassembly
11.1
Introduction
This chapter provides details about the following:
• Routine maintenance
• Preventive maintenance (inspection and cleaning)
• Safe handling of CMOS and LDMOS devices
• Disassembly and reassembly of the repeater
• Repair procedures and techniques.
11.2
Routine Maintenance
NOTICE: It is recommended that the repeater is cleaned with a soft dry cloth while in service.
The repeater and ancillary equipment have been designed with state-of-the-art technology and operate
under software control, thus requiring minimal routine maintenance. Virtually all repeater operating
parameters are monitored and self-corrected by the Modem and the firmware it runs, which makes
adjustments and tuning virtually unnecessary.
Provided that the equipment is installed in an area which meets the specified environmental
requirements, the only routine maintenance task required is the calibration of the repeater reference
oscillator circuit.

Cleaning Procedures
The following procedures describe the recommended cleaning agents and the methods to be used
when cleaning the external and internal surfaces of the repeater. External surfaces include the top
cover and repeater enclosure.
Periodically clean smudges and grime from exterior enclosure. Use a soft, non-abrasive cloth
moistened in a 0.5% solution of mild dishwashing detergent and water solution. Rinse the surface
