Frequently Asked Questions

FREQUENTLY ASKED QUESTIONS:
I'm hearing humming or buzzing sounds/static on the line. What's wrong with my
phone?
1. Try a different handset and/or line cord. If the phone works correctly; replace the appropriate
cord(s).
2. If you have other equipment installed on the lines, it can cause interference on your system. Try
unplugging the other equipment. If the static goes away, try installing the adjunct device with a
different line cord or in a different jack.
3. If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone
jack that has a phone. The DSL signal can cause static/noise, squealing (similar to fax tones), caller ID
disruption and other issues on your line. DSL filters block the high frequency DSL signals from being
transmitted to the telephone. If you are not using the DSL filters provided by the telephone company,
this will cause static/noise and possibly caller id issues on your phones.
In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then
connect a telephone cord between the filter and your phone. Please contact your service provider to
obtain DSL filters and installation information.
4. Are you using the speakerphone when this problem occurs? Your speakerphone will only allow
sound to travel in one direction at a time. It can either receive or transmit; it cannot do both at once.
Background noise can cause the unit to seem like it is cutting in and out, when really it is switching
modes Any transient noise like a subtle cough or a fan in the background can cause the unit to switch
modes. If you are using a speakerphone where there is background noise, please use the MUTE button
when you are not speaking. This will prevent the unit from switching modes when you are not speaking.
5. If you have connected this telephone to a phone jack that has not been used before, or that has not
been used recently, there may be problems with this jack that you are not aware of. Use a telephone
jack that you know is in proper working order.
6. You may have a line problem. To test for a line problem, test your unit at another location. If your
unit works at another location, contact your local telephone company.
7. If your phone shares a power outlet with a modem, or if it is plugged in to a shared surge protector, it
may create static or noise. Try plugging the phone (or modem/surge protector) in at a different
location. If this solves the problem, re-locate your phone or modem farther apart from one another, or
use separate surge protectors.
8. Make sure that you are using the AC ADAPTER that came in the box with your unit. Using the wrong
AC ADAPTER with this phone, may cause the unit to malfunction.
