TELEPHONE OPERATION

Headset Jack

You can use this telephone hands-free when you install a 2.5 mm headset
(SKU 24099), purchased separately.
Plug the headset into the jack located on the right side of the handset
(under the small rubber flap). Do not force the connection, but make sure
the plug fits securely.

Operating Range

This cordless telephone operates within the maximum power allowed by
the Federal Communications Commission (FCC). Even so, this handset and
base can communicate over only a certain distance — which can vary with
the locations of the base and handset, the weather, and the construction of
your home or office. For best performance, keep the base antenna fully
upright.
If you receive a call while you are out of range, the handset might not
ring — or if it does ring, the call might not connect when you press P.
Move closer to the base, then press P to answer the call.
If you move out of range during a phone conversation, you might
hear noise or interference. To improve reception, move closer to the base.
If you move out of range without pressing O, your phone will be
left "off the hook." To hang up properly, walk back into range, periodically
pressing O.
