buzzing, and the video hum-bars that can result from typical in-line
suppressors. Further, our cable and satellite suppressors are TIVO
friendly as well as HD-Digital Television ready. Both DC carrier
signals as well as high bandwidth signals can pass through our
circuit. In fact the bandwidth is less than 0.1dB loss at 1GHz!
To connect your cabling to these in-line protectors, simply follow the
in and out indications marked next to the Telco, and Cable / Satellite
connectors.
Note:
It is not possible to make an in-line cable / satellite protector
"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-8. 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-8) then the protection
circuit is damaged (assuming it worked properly before the storm or
catastrophic event).
