INGER REPETITION RATE CHANGE DURING
CONVERSATION AND RINGER MODE
The generated melody is built up out of three frequencies.
These frequencies are generated successively in a
selected repeat frequency.
There are four steps and they can be changed:
Via the EEPROM programming procedure (See
Section 5.3.2)
During conversation mode, when the function keys
option is chosen, with a special key sequence
During active ringer by a simple key press.
In conversation mode the procedure is as follows:
Put the set in conversation (supply necessary)
Depress PR (ringer program key)
Press one of the four acceptable repeat frequency keys
(9,
, 0 or #) see Table 10.

The newly selected value is directly stored into EEPROM.
During active ringing the PR key is not used, the procedure
is as follows:
Active the ringer (only then this repetition rate correction
is possible)
Press one of the four acceptable repeat frequency keys
(9,
, 0 or #) see Table 11.
