if required. Contact your ADSL provider if you are unsure if microfilters are needed
for your installation.

About Microfilters

A microfilter is a small device designed to reduce interference between ADSL signals
and your regular telephone signals.
The use of microfilters is only required if your ADSL modem and your telephone
devices share the same wiring. This is known as ‘splitterless’ ADSL. Without
microfilters, ADSL may cause background noise on your phone, Additionally, ADSL
data transfer may be interrupted by phone calls.
If microfilters are required, you must install one on each telephone device that shares
the same wiring as the ADSL signals, including telephones, answering machines, and
fax machines.
If your installation uses a splitter, it should not be necessary to use microfilters as
ADSL data is carried on separate wiring up to the point of entry to your location.
Your package may or may not include a microfilter. If you are unsure as to how to
connect the microfilter, orwhether or not one is necessary, contact your
ADSL provider.

Connecting the Microfilters

To install the microfilter, plug your phone into the microfilter, then plug the microfilter
into your telephone jack, as shown below.
You must use one microfilter per telephone device in your location. Do not install a
microfilter on the cable that connects your ADSL device to the telephone jack.
