How to Install a DSL Filter Correctly So it Will Not Damage
- 1). Unplug any device, such as a fax machine, land-line telephone or a dial-up modem, that is plugged into your DSL phone line.
- 2). Plug the DSL filters into every phone jack in use, except for the phone jack the DSL modem is plugged into.
- 3). Plug the phone device into the other end of the DSL filters. Make sure they are plugged in securely. Check the connection by picking up a telephone. If you hear a dial tone you have installed them correctly.
