SETTING THE DELAY OF DOOR ALARM
The door check indicator is lit when the door is opened, and the buzzer sounds with some delay to notice
the door opening.
The delay time (between lighting of the door check indicator and activation of the buzzer) can be changed.
Set an appropriate delay time according to the condition of use to prevent the rise of chamber
temperature occurring as a result of the door being left open for too long.
 Setting range of delay time: between 1 and 15 minutes
 Initial setting (factory setting): 2 minutes
Example: Change the delay time to 3 minutes from 2 minutes
► Following shows a sample setting. Set the desired delay time according to the condition of use.
