Getting started
Optional headset
Make sure the headset is firmly plugged into the headset jack under the
rubber flap on the right side of the telephone. There is a low pitch (error)
tone if you press HEADSET when the headset is not plugged in.
For hands-free telephone conversations, use any industry standard 2.5 mm
headset (purchased separately). For best results, use an AT&T 2.5 mm headset.
To order an AT&T 2.5 mm headset, visit our website at

Plug 2.5 mm headset into
the jack on the right side
of the telephone base
(beneath the small rubber
flap).
NOTE: If the sound quality of the headset is poor, try unplugging it, and firmly plugging it in
again.
