SECTION 4 MAINTENANCE
In order to ensure that the STR-1800 system is always ready for operation, it should be checked
periodically so that potential defects may be discovered and corrected before they develop into any serious
damage or system failure. A minimal preventive maintenance program will significantly increase the
systems life span.
This section describes the necessary preventive maintenance checks and tests the user can perform to easily
identify most defects and problems. Any other defects or problems discovered during the normal operation
of the system should be noted for future corrective measures.
CAUTION
Stop the operation of the system immediately if a problem is noted during
normal operation which can otherwise damage the system.
This section also describes the corrective maintenance checks that can be performed on the STR-1800
system.
4.1 Maintenance Concept
The maintenance concept for the STR-1800 system is limited to the removal and replacement of the entire
unit.
4.2 Preventive Maintenance Requirements
The following is a recommended timetable for performing preventive maintenance checks on the STR-
1800.
CAUTION
Primary power to the radio must be turned OFF when
performing preventive maintenance on the equipment
4.2.1 Inspection
The STR-1800 system should be inspected periodically for defects or physical damage developed during
operation. Inspect all the interface cables to and from the system for cracks, breaks and proper seating with
their mating connectors on the card. Inspect all cables for frayed, broken or damaged wires. In addition,
inspect all STR-1800 connections for accumulation of dirt, grease, or any foreign material that can cause a
non-connection. If a cable is found damaged or non-repairable, it should be replaced before operating the
system again.
Inspection should be performed at least once every month. The frequency of inspection should be increased
for units exposed to dusty or heavy particulate environments.
5.2.2 Cleaning
Clean the outside surfaces and areas around the connectors periodically. Clean the surfaces with a clean,
soft, lint-free cloth. Clean the areas around the connectors with a soft bristle brush. To remove grease,
fungus, or corrosion, use a cloth dampened with an appropriate electronics cleaning fluid. Cleaning should
be done at least once every month. The frequency of cleaning should be increased for units exposed to
dusty or heavy particulate environments.
