Your telephone can accommodate up to eight cordless handsets. You can add
new handsets (AT&T model EP590-3, purchased separately) anytime. Up to three
handsets can be on a call at the same time.
The handset provided with your telephone sys-
tem is automatically registered as Handset 1.
Additional handsets will be assigned in numerical
order (2, 3, 4, etc.) when they are registered.
Before using a separately purchased handset, it
must be registered with the telelphone base. Put
the new handset on the telephone base. Press
SELECT/MENU, followed by ^DIR once to reach the
Register Handset screen. Press SELECT/MENU to
confirm.
When the handset has synchronized with the tele-
phone base, the screen on the handset will show
Registration in progress.
When the handset is successfully registered to the
telephone base, the telephone base will generate
a confirmation tone. The newly registered handset
will be assigned the lowest extension telephone
number which has not previously been assigned to
another system handset (2-8).
The newly registered handset will sound a confir-
mation tone.
