I have a Panasonic DECT 6.0-Series 3-Handset Cordless Phone System with Answering System (Model KX-TG1033S) which includes 1 base unit, 3 handsets and 2 chargers. All of the handsets have NEW Panasonic NiMH 700mah AAA Rechargeable Batteries.

When the phone rings, a buzzing sound emanates from the handsets. (The caller does not hear the buzzing sound).

How can I eliminate the buzzing sounds?

Do you have a wireless router? You might try turning that off to see if it's interference from it. What's the frequency of your phone system? Sometimes WiFi routers interfere with cordless phones. ?(?)?
