This guide is for installation only. For more detailed information regarding
the product and its features, please refer to the user manual located on the
included CD-Rom.
Before you begin:
1. If you have had a service technician install your DSL Line, please skip
to Step 1 “Review Package Contents.” If you are installing DSL
yourself, please follow all instructions.
Install a “Z-Blocker” phone filter at EACH telephone wall
jack in your home.
Q: Why do I need these filters?
A: DSL service shares the line with your regular telephone service. In-line
filters prevent these services from interfering with each other, improving both
the telephone audio and DSL data rate.
Disconnect the existing cord from the wall jack.
Plug the LINE end of the
filter into the wall jack.
Plug the device into the
PHONE jack on the filter.
Use only filter for all devices
sharing the jack.

Sharing your phone jack with the modem and another
device.
If you would like to share your phone jack with the modem and your phone,
then use a standard 2-line adapter.
Install the 2-line adapter into the wall jack.
Plug the RJ-11 cable into one adapter jack.
Plug the Line end of a “Z-Blocker” filter into the other adapter jack.
Plug your telephone devices into the PHONE jack on the “Z-Blocker”
filter.

Installing the “Z-Blocker” filter on a wall-mounted
telephone, using the wall-mount filter.
Remove the phone. On some phone you must pull out a locking lever
before removing the phone. Then push up on the phone and pull it out
from the wall.
Slide the filter locking tabs (located at the top and bottom on the front
of the filter) to the UNLOCKED position.
Place the filter over the existing wall outlet, aligning the plug and
mounting slots with the socket and mounting tabs on the existing
outlet, then push into place.
Move the locking tabs to the LOCKED position as indicated in the
drawing.
Mount the telephone. If your phone has a locking lever, be sure it is
unlocked before you mount it. Position the phone’s plug and mounting
slots over the filter jack and metal mounting pegs. Press the phone in
and pull down until secure.
If desired, install your ADSL or Home Phoneline Network (HPN)
device cord into the jack on the left side of the adapter. An answering
machine may also be attached to the jack on the right side of the filter.

Filter Installation Tips
DO NOT install a filter on your DSL modem or on any broadband
devices.
Check the orientation of each filter.
1. PHONE jack towards the telephone device.
2. LINE connection towards the wall jack.
Try to limit the number of filters in your home to the fewest practical.
Do this by:
1. Using one filter to isolate several devices.
2. Not installing filters on unused phone jacks.
Do not use more than one filter for each telephone device or group of
devices.
Plug the filter directly into the wall jack using only the attached short
cord. If this cannot be done, then use a twisted-pair cable like the data
cable for the modem (i.e., NOT a flat phone cord) to connect the filter
to the wall jack.
