SETTING THE ALARM TEMPERATURE
Setting the high-temperature alarm
An abnormality (chamber temperature rise) is indicated by the blinking of red LED lamp and the chamber
temperature display and the buzzer sounding (15 minutes after blinking) if the chamber temperature
exceeds the set value of the high-temperature alarm. Always set the high-temperature alarm to protect
stored items from damage resulting from an increase in temperature.
 Setting range for high-temperature alarm:
between 2 o C and 14 o C higher than the chamber set temperature
 Initial setting (factory setting): 5
o
C higher than the chamber set temperature
Example: Change the high temperature alarm to chamber temperature plus 3
o
C from chamber
temperature plus 5 o C
