POTS Splitter (DSL Microfilter)
Your phone line carries with it both phone calls and Internet signals.
When you are using the Internet, the connection produces high-
pitched tones that can affect your voice calls when using the phone.
Installing a Plain Old Telephone Service (POTS) splitter separates the
two signals and eliminates the noise.
To setup a telephone on the POTS Splitter (DSL Microfilter):
a. Locate the phone jack in your house.
b. Insert the POTS Splitter into the phone jack.
c. Plug one end of the telephone cable from the POTS Splitter's TEL
port and then plug the other end into the telephone.
4. Connect the power adapter from the modem router's 12V 1.0A DC
port into the electrical outlet.
5. Press the ON button to turn ON the device.
