Headset
You can use this telephone
hands-free when you install
any industry standard 2.5 mm
headset (purchased
separately). For best results
use an AT&T 2.5 mm headset.
Plug the headset into the jack
located on the left side of the
handset (under the small
rubber flap). Do not force the
connection, but make sure the
plug fits securely.
