Information on using the phone
You have decided on the Aton C28 telephone - an efficient telephone in a mo-
dern design. The telephone is simple to operate. The telephone is intended for
use in the Swiss analogue network.
Menu driven operation
You only need to make the settings once or only seldom. This is done with a
simple menu driven operation.
Opening the menu: Press the R-key and the redial key
at the same time. (The„P“ for „Programming-mode“ appears
in the display).
Select functions: The functions are all on one level and are
selected with the arrow keys.
Change setting: The settings can be change directly using
the OK-key or you will get to a second level to enter digits or
characters. With some functions you have to enter a 4-digit
PIN code that protects the function.
Leaving the menu: You can use the C-key to delete parts of
the input, to return to the first level or end programming. After
the end of programming the „P” in the display disappears.
Please note the following information:
• If you enter a „wrong key“ (related to the corresponding function) during the
programming process, the procedure is aborted without saving the changes.
• If you do not press any key for 40 seconds while you take out a specific
programming step, the procedure is aborted without saving the changes.
• You can interupt the programming process without saving the changes by
lifting and replacing the handset.

word disappears before requesting further functions or ending programming.
• If you want to alter several functions protected by a PIN one after the other,
you only need to enter the PIN for the first function (exceptions: reset/restore
the delivery status).
• When you program a telephone number under a memory location, you can
enter manual dialling pauses via the redial key. In the display, a pause is
indicated by the symbol „P“ in the upper display line. If you made a mistake
when entering the telephone number, just use the C-key to erase it.
• If you have stored an Exchange Identification Code you have to enter this in
front of the phone numbers that you want to enter in a memory (phone
numbers for speed dialling, abbreviated dialling, assistance call function and
dialling restriction).
