2) Inspect the unit to see that the two power sup-

ply LED DC indicators are lit (remove any dust

or debris that may obscure the LEDs). This will

verify that DC power is flowing properly. Check

all hardware for tightness.

3) Compare system performance to initial perfor-

mance levels measured when the system was

first installed. The lack of signal can be traced

to a malfunctioning amplifier by progressive sig-

nal monitoring from the output (far end) to the

input end of the system noting the area where

the signal returns to normal level. The next

amplifier toward the output end of the system

will probably be the one that failed.

Measure the gain at any convenient frequency

in the working frequency band to verify that the

performance is still within specifications.
