Memory recall state (only UBA2051x)
Repertory numbers can be dialled out after or before
entering manual dialling, last number redial and by
entering the memory locations in successive order.
Repertory recall is not possible as long as a dial out is
pending. The three direct memory locations are numbered
[M1] to [M3] and the ten indirect memory locations
[MEM] [1] to [MEM] [0].
The stored numbers can be dialled by using one of the
following procedures:
Press one of the direct memory keys [M1] to [M3]
or
Press [MEM], followed by one of the numeric keys
[1] to [0], corresponding to the memory locations 1 to 10.
In case [R] is included in one memory location, when the
LNR capacity is exceeded by using it, the LNR function is
inhibited.
Program state (only UBA2051x)
The program state can be entered from the conversation
mode (on-line) when no dial out is pending. Pressing the
[STORE] key in this state puts the UBA2051x in the
program state and also clears the LNR memory. Pressing
the [STORE] key again in the program state will restart the
program sequence.

Leaving the program state
The program state can be left in one of the following
ways:
– By going on-hook; the entered digits are stored in the
– By ending the store procedures properly (see below),
Programming repertory numbers
A maximum number of 32 digits can be stored in the
memory of repertory numbers (including access pauses,
tone switch and flash) and can be achieved by using the
following procedure:

dialler and ringer functions
LNR memory
resulting in a proper store of the programmed item.

– Press [STORE]; the LNR memory is cleared
– Press the sequence of digits that must be stored; the
– Store the number in the memory.
Memory overflow
If more than 21 digits are entered the old memory
contents is kept and the LNR memory is cleared. All the
following digits are ignored, except the [STORE] key.
The memory overflow state can be left:
– By going on-hook
– By pressing the [STORE] key again to restart the
Clear repertory numbers
Clearing a memory location is possible by using the
same procedure as for storing a number, except that no
telephone number is entered:
– Press [STORE]; the LNR memory will be cleared
– Press one of the memory keys.
Notepad function
In the conversation state it is possible to store a 21 digit
number into the LNR memory, which may be dialled
after an on-hook/off-hook action. The procedure is as
follows:
– Press [STORE], the LNR memory will be cleared
– Press the sequence of digits that must be stored; the
– Go on-hook/off-hook.
