6.3.1

Visual Inspection

At one-month intervals, the Indoor SSPA should be visually inspected for physical defects. If the
equipment is subject to severe environmental conditions, inspections should be performed more
frequently.
The event log is a good source for clues that could indicate an intermittent or marginal condition.
Any increase in reflected power, temperature or unexplained fault conditions could point to a
deteriorating condition.
The circuit breaker must be off while the following general inspection is performed.
Perform the following visual inspection:
•
Check that all connector plugs are properly seated in their mating connectors and have not
been damaged. Only have a service technician replace any bad connector plugs and reseat any
that are dislodged.
•
Inspect cables for signs of discolored, broken, or bad insulation. A service technician should
repair or replace cables as needed.
• Inspect all waveguide for discoloration, cracks, loose connectors, and improper sealing.
Contact a qualified service technician for repairs.
•
Check for other defects. These include, but are not limited to, wear, breakage, deterioration,
fungus, excess moisture, and mounting integrity. Contact a qualified service technician for
repairs.
• Inspect the air intake filter. This is a removable and washable filter; clean it if necessary.

Unit Cleaning

Look for signs of dirt or moisture contamination, which can cause short-circuiting, arcing,
corrosion, or overheating. Use a lint-free cloth, a small vacuum cleaner, or a compressed-air
blower at low pressure to clean contaminated areas with.
