I'm trying to access your on-line info regarding my Expandable Digital Cordless Anwering System W/2 Handsets. I'm unable to find the material because you don't list the model numbers of my hardware to select from. I want to print a copy of the operating instructions for my use to replace the original One that was destroyed by our puppies and is beyond repair or use. I need your help. I don't want to purchase a new operating manual if one can be obtained on-line. Thanks
