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.
