4.5 PREVENTIVE MAINTENANCE
Preventive maintenance is the systematic, scheduled care and inspection of equipment to prevent equipment failure
and to reduce downtime. This consists of keeping the equipment clean, dry, and dust-free. Clean equipment using a
soft brush, a moist sponge, and a cloth. Check all hardware for looseness and make sure units are secure. Check all
connectors for debris, damage or corrosion. Ensure protective caps are in place if connectors are not in use. Check
all cables and antennas for damage (cracks, breaks, or strains) and repair or replace as required.
