The pre-emphasis is 2.6 dB. The DTMF tones are
according to CEPT recommendations.
Tone Ringer (Melody/Volume)
The tone ringer incorporates two basic selection, namely 2-
tone or 3-tone melodies. The default set-up selection is the
3-tone ringer.

The chosen melody will be heard in the loudspeaker during
programming. Pressing the [PG] key will end the procedure
and the last selected melody will be stored.
When 2-tone melody is selected through the set-up
procedure, it is possible to chose the following melodies:

Repetition rate means that a sequence of 6 frequencies is
repeated 1, 2, 4, 5, 6 or 10 times within 1 second.
Pacifier Tone
Any key entry is acknowledged by a pacifier tone (key-in
tone) of 1333 Hz. The pacifier tone can be
enabled/disabled through set-up programming.
