Basically, all the acoustic signals are played in the melody and at the
volume selected by the user.
The signal transmitter can only be ended with the STOP key.

To inform the user that the automatic self-test has been
successfully completed, the selected melody is played.
2 Furnace head open and temperature below 550 °C / 1022 °F
To inform the user that the temperature in the open furnace head
has dropped below 550 °C / 1022 °F, the selected melody is
played (5 seconds). In other words, the furnace head is basically

To inform the user that the temperature in the open furnace head
has dropped below 320 °C / 608 °F, the selected melody is
played.
If the first playback (10 seconds) is not acknowledged with the
STOP key, a second playback sounds after 5 minutes (for
5 minutes). After that, no further signal is played.
If one of the two playbacks is acknowledged with the STOP key,
the signal transmitter is switched off immediately and no further
signals indicating the cooled furnace head will be sounded.
4 For error messages
Error messages are acoustically supported with the ‚error melody‘
(endless beep). The signal transmitter may be switched off with
the STOP key, while the error message still remains visible. If the
error message is acknowledge with the ESC key, the signal
transmitter is also switched off.
