ET-177 (430-0583) Preparation Faxback Doc. 6727 You can connect your phone on a flat surface such as a table or counter top, or mount it on a wall plate or directly on a wall. Notes: If you do not have a modular phone jack, you can either update the wiring yourself or the phone company can update it for you. Radio Shack Stores sell the jack and adapters necessary to convert from older wiring methods to modular wiring. The telephone company will charge you for installation of necessary jacks. The telephone company will ask you for the USOC number of the jack to be installed. This number is RJ11C (or RJ11W for wall mounting). (br/all-6/29/94)
