Furman PST-8D Manual página 6

Note:
It is not possible to make an in-line cable or satellite protector "virtually
maintenance-free" as we have accomplished with the 120 VAC line.
This would necessitate limited signal bandwidth that would not allow
the signal to pass. Under extreme conditions, it is possible that
the surge suppression in one of these devices could sacrifice itself
after a catastrophic event. If the telephone, cable or satellite signal
will no longer pass through our protector, please send your Power
Station to Furman for servicing. To test this, simply disconnect
the incoming and out going cable from the PST-8D. Connect the
incoming connector to the component that formerly received the out
going connector, thus by-passing the in-line protection. If the signal
is present (but not when used with the PST-8D's) then the protection
circuit is damaged (assuming it worked properly before the storm or
catastrophic event).
Circuit Breaker
If the PST-8D is connected to an AC outlet where sufficient voltage
is present, the unit should operate properly with the protection OK
indicator lit, after the main power switch is turned to the on position.
If the unit still does not function under these conditions check the
circuit breaker button! It is the round black button adjacent to the
incoming AC cord. If the circuit breaker trips immediately, there may
be too great of a current load placed upon it. Simply disconnect one
product at a time until this no longer happens. If the breaker trips
with no components connected, there may be a wiring defect that
requires Furman service.
