phone number (without pre-
dialling).
Telephone numbers from the redial
list can only be pre-dialled.
Please note that once a connection
is established you can hear the
other party, but they can only hear
you when you lift the handset.

Last Number Redial

You make a call from the Open-
Phone 52 in the normal way: Lift the
handset and dial a telephone num-
ber. You also accept calls in the
usual way, by lifting the handset.
On the following pages you will find
the basic functions of your tele-
phone, with the section entitled
"Features" explaining the more
extensive enhanced functions.
Lift the handset and press the redial
key. Your OpenPhone 52 now dials
the last telephone number you
entered
or
press the redial key several times
(on-hook). The last five telephone
numbers dialled are displayed con-
secutively. When you lift the hand-
set the displayed telephone number
is dialled.

Automatic Callback

If you fail to get through to the

had called you back.

Press the softkey.
After a few seconds a message
appears telling you that your call-
back request has been received and
saved by the ISDN. You can now
hang up.
A callback request is saved by the
network, not in your telephone or
the telephone of the dialled party.
This means that automatic callback
is not possible from all subscriber's
phones and in these cases an error
message appears. To delete a call-

softkey when the callback is sig-
nalled.
The connection charges for the call-
back service are normally incurred
by you.*
NB: If the "Callback" function is
unavailable, "Callback" does not
appear as a softkey.
* For further information about callback calls
please contact your network operator.
