USRobotics 9003 Connect Microfilters If Necessary, Connect Microfilters to Telephone Devices

Step 1. Connect Microfilters (If Necessary)

•If your package didn’t include microfilters, and your ISP didn’t provide any: Skip to Step 2 of these instructions.

•If your installation requires microfilters: Install one on each telephone device that shares the same phone line as the ADSL signal. (Tele- phone devices include telephones, answering machines, and fax machines.)

A microfilter is a small device that reduces interference between ADSL signals and telephone signals. You only need a microfilter if the ADSL router and telephone device share the same phone line. If you don’t use a microfilter, you may experience background noise on your telephone during data transmission. Also, telephone calls may interrupt data transmissions.

Connect Microfilters to Telephone Devices

To install the microfilter, plug the phone into the microfilter, and then plug the microfilter into the telephone wall jack. Do not install a microfilter on the cable that connects your router to the telephone jack unless your microfilter has a connection for both the telephone and the DSL device.
