SETTING OF DELAY OF DOOR ALARM
The door check indicator is light when the door is opened, and the alarm buzzer sounds with some delay
to notice the door opening.
The delay time (between lighting of the door check indicator and activation of the alarm buzzer) can be
changed.
Set an appropriate delay time according to the condition of use to prevent the rise of chamber
temperature resulting from inadequate door close.

1 and 15 minutes
