ETTING OF
Setting of high temperature alarm (freezer)
The abnormality (chamber temperature rise) is noticed by blinking of alarm indicator and chamber
temperature display and sounding of the buzzer (15 minutes after blinking) if the chamber temperature
exceeds the set value of high temperature alarm. Always set the high temperature alarm to protect the
storage items from damage resulting from temperature rise.
Setting range of work temperature for high temperature alarm:
Between 5
o
C and 15
o
C higher than the chamber set temperature
Initial setting (factory setting): 10

C
Details: Change from ”the setting that the high temperature alarm works at 10
o
C higher than the chamber set
temperature” to ”the setting that the high temperature alarm works at 5
o
C higher than the chamber set
temperature.”
