Adding a polarity guard to NE tone Princess with QNB17A network

[RotoTech99]

Dear Unibeldi:

Attached is a .pdf document for adding a separate polarity guard to a QNB17A network equipped NE Princess with either a 25H4 or 35H4 dial.

The polarity guard is a 2 wire 2 terminal AT&T Type polarity guard; Please look at the document and verify if the connection and wiring information is correct, please.

Ktownphoneco gave me the information and said I could post it, but he recommended I double check it with you first.

Please let me know, all adbvice and feedback appreciated.

Thank you, Rototech99
