I took a look at your filter and my
phone and the line cord that goes from the wall to the phone. It looks like the filter
could plug into the phone jack or into the telephone. What's the best place to put it?
We recommend that you plug the filter directly into the telephone. This is because
the line cord could be picking up interference. |

Isn't telephone interference a telephone
company problem? Shouldn't I call them?
It makes good sense to explore all of your options. The telephone company is
generally responsible for providing useable (interference-free) service to the
"customer interface" where the outside phone line enters the home or building.
Typically, the customer is responsible for the inside wiring. Be sure your phone company
explains their policies and rates. |

I tried your filters and they didn't
stop the interference. Can I get my money back?
Yes, you can. We offer a 90 day money back guarantee on all filters purchased from
K-COM. Simply return your purchase for a prompt refund. We do want you to know that K-COM
Filters are in use worldwide, solving telephone interference. You might want to contact us
first to discuss your particular situation. We may be able to offer information to help
you solve the problem. Phone toll-free 877-242-4540. |

There is interference on my wall phone.
How do I plug in a filter behind the wall?
Usually there isn't room to plug a filter into the back of a wall-mounted
phone. That's where the K-COM RF-2 Hard Wired Filter comes in handy. Installation is
simple and complete instructions are included. Once the RF-2 is connected, it can be
pushed back into the wall so it doesn't get in the way. |

I have been using a K-COM Filter with
good results until yesterday. My phone went dead and when I removed the filter and plugged
the line straight into the phone, the phone worked again. What happened?
In 99.9% of similar cases, the filter failed as a result of lightning or static
discharge on the telephone wiring. When this happens, the filter can act like a fuse and
often protects equipment (phone, modem, etc.) from damage. If your K-COM Filter ever fails
for any reason, return it for free repair or replacement. |
|
Do you have filters for 2-line
telephones?
Yes! The K-COM RF-1 Two Line Modular Filter plugs into the line input of
2-line telephone sets that use one line cord for the two phone lines (RJ-14 connectors).
If your 2-line telephone uses two single-line inputs, simply use two K-COM Single Line
Modular Filters. |
|
Do your filters work with FAX and
Answering Machines?
Yes! Telephone Interference can disrupt normal operation of these devices.
The correct choice here is the K-COM RF-1 Single Line Modular Filter. It's best to install
it at the line input to the equipment. |

In my house I have five telephones,
three computer modems, one answering machine and a phone line connection to a satellite
receiver. Am I going to need a filter at all of those places?
Isn't it amazing how much phone equipment we're using these days? You've just
identified 10 places where equipment connects to the telephone wiring in your house. While
we would happy to sell you 10 K-COM Filters, there are two things you should know: 1) One
of the devices connected to the phone line might be the source of the interference
problem; 2) Our Telephone Interference Technical Bulletin discusses similar situations and
offers tips on tracing down the problem. (Faulty Telephones) For technical support call
K-COM toll-free 877-242-4540. |

My small business uses a 6-line
Panasonic telephone system. We're getting interference from a nearby radio station. Can
you get that loud mouth DJ off my phones?
Yes. Say goodbye to Johnny Rocker. You have an electronic key phone system. These
are the most common systems used in small businesses and today's equipment includes analog
and digital technology. You'll want to install K-COM RF-1 Two Line Modular Filters at each
telephone set; just plug them in to the line input. And you should use K-COM Filters at
the input and output of your system controller (Key Switch Unit). This is a simple matter
of selecting the K-COM Filters that match your controller's wiring configuration.

I spend a lot of time online and a
friend told me your filters make modem connections run faster. Is that a joke?
That's no joke! As you know, the speed of your modem connection can be influenced
by numerous factors. One of these is "common-mode noise" which your ear can't
hear but your modem can. It has greatest effect on users in small town and rural
environments where telephone service requires very long runs of wire from phone company
equipment. K-COM Filters can reduce this type of noise and improve modem connection speed.
K-COM Filters also help to provide spike protection. Some spikes are not serious enough to
cause damage but contain enough energy to make you lose your modem connection. Here, your
K-COM Filter can actually reduce lost connections. And, K-COM Filters help protect modems
from larger, potentially damaging spikes, although they are not sold as lightning
protection or spike protection devices. |
