Troubleshooting

 

 

 

 

 

 

 

Noise interference on

Make sure the extension phone is properly filtered. If a

 

 

 

the extension telephone

filter is installed, this noise could be a faulty filter, line

 

 

when using the modem

cord, phone service, phone, or the Elite1Modem. While

 

 

 

using the modem, try to eliminate these possibilities in

 

 

 

the following order:

 

 

 

1.

Turn OFF the Elite Modem. Make a call on your

 

 

 

 

extension phone and check the noise. If the noise is

 

 

 

 

gone, the modem may have a fault.

 

 

 

2

Exchange the line cord between the modem and the

 

 

 

 

wall jack with a known good line cord. Check the

 

 

 

 

noise. If it persists, place the known good line cord

 

 

 

 

between the modem and the phone.

 

 

 

3.

If you have a known good spare phone, use it to

 

 

 

 

replace the suspect phone. If the noise is goes

 

 

 

 

away, the telephone is bad. If the noise persists, it

 

 

 

 

may be the Elite Modem. Contact distributor

 

 

 

 

technical support.

 

 

 

4.

Call your phone service and ask them to check the

 

 

 

 

line for noise. If they assure you that the noise

 

 

 

 

problem is not with their equipment, check your

 

 

 

 

phone unit.

 

 

 

 

 

 

Noise interference on

The Elite Modem has a built-in filter to prevent this. The

 

 

 

the telephone

noise could be a faulty line cord, phone, the Elite

 

 

connected to the modem

Modem, or it could be coming from your phone service.

 

 

 

Try to eliminate these possibilities in the following order:

 

 

 

1.

Disconnect the phone from the modem and connect

 

 

 

 

it directly to the wall jack, bypassing the modem.

 

 

 

 

Disconnect the modem from the wall jack. If the

 

 

 

 

noise is gone, you should probably solve the

 

 

 

 

problem by replacing the Elite Modem. If the noise

 

 

 

 

persists, it may be your phone service.

 

 

 

2.

Check your telephone line cords by exchanging

 

 

 

 

them one at a time with a known good line cord. If

 

 

 

 

you eliminate the line cords as a possibility, check

 

 

 

 

the phone unit.

 

 

 

3.

If you have a known good spare phone, use it to

 

 

 

 

replace the suspect phone and reconnect the

 

 

 

 

modem. A new phone may eliminate the noise. If the

 

 

 

 

noise persists, call distributor technical support.
