Operation; How To Turn The Freezer On/Off; Changing The Set Temperature - STRILING Shuttle ULT25NE Operating Manual

4. Operation

Important changes to the freezer settings require sustained button pushes.
This helps prevent accidental changes to the settings during transportation.
Some sequences require a three-second button press and hold while other
sequences require a five-second button press and hold.
For example,
Turning the freezer ON requires a three-second press and hold (two beeps).
Turning the freezer OFF requires a five-second press and hold (three beeps).
The default display is the chamber temperature. Other displays such as Setpoint,
Alarm Postpone, etc., are marked with a letter such as S (Setpoint), h (Alarm
Postpone), etc. These secondary displays revert to the default display after
approximately eight seconds of button inactivity.
