Press and release button HARD / SOFT: LED HARD
will switch off.
5.1 According to the model, the display will show the work-
ing setpoint during the blast freezing or the blast freez-
ing cut off temperature.
5.2 Press and release button UP or button DOWN in 15 s
to modify these values.
6.
Press and release button START / STOP: LED
and
LED
will firmly remain switched on and it will be
started the test for the verification of the proper in-
sertion of the needle probe.
6.1 If the test is successfully completed, the cycle will be
started.
