SETTING OF DELAY OF DOOR ALARM
The door check indicator lights 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.
Setting range of delay time: between 1 minute 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.
