Troubleshooting
I experience poor sound quality when using the speakerphone.
•For increased sound quality while using the speakerphone, place the handset on a flat surface with the dial pad facing up.
•When using a speakerphone, controlling background noise in your environment is essential. While you are listening to your party, press the MUTE softkey to temporarily turn your microphone off. When it is your turn to speak, remember to press the MUTE softkey again to turn the microphone on.
•Excessive background noise will cause a speakerphone to fade in and out. Try controlling the background noise by turning off any audio devices near the speakerphone. Also, try to avoid interrupting the person at the other end of the conversation while they are speaking. If background noise cannot be controlled, you should terminate speakerphone operation and return to normal handset mode.
I hear other calls while using my phone.
•Disconnect the telephone base from the telephone jack, and plug in a different telephone. If you still hear other calls, the problem is probably in your wiring or local service. Call your telephone service provider.
While on a call or playing messages, there is too much noise, or the voice sounds tinny, shrill or flat.
•While on a call or playing messages, press the EQ 
button on the side of the handset until you find the settings that sounds the best.
