Memory dialling is cascadable up to a the maximum
of 31 digits/data.
Tone Generator
The tone generator incorporates the DTMF tones, 3
frequencies for the tone ringer and pacifier tones.
DTMF
The DTMF generator provides 7 frequencies.

The MF output level can be set through set-up
programming. The range is from -18 dBm to -6 dBm
in 1 dB steps.

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.

Press [PG] to store and terminate
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.
