How to use

Place the thermometer in the area of the refrigerator or freezer you wish to monitor, such as a middle shelf or compartment representative of typical storage conditions.

Usage recommendations

Position the thermometer away from direct airflow of vents and not immediately adjacent to door openings to obtain a representative temperature for stored items. Check readings periodically and place the device where it can monitor the typical storage zone for perishable foods. If the thermometer indicates temperatures outside recommended storage ranges, adjust the appliance settings or relocate items as needed.
