Phone not working when plugged in surge protector

Unplug and reconnect the phone/fax input cable with the surge protector. If that does not work, plug the phone/fax directly into the phone wall jack. If the phone/fax works in the wall jack, the surge protector has been damaged by a surge or could be defective (phone/fax protection circuits are separate and not related to the indicator lights.) If the phone does not work, check your phone in another outlet as you may have a defective phone.
