Using the Thermometer
High/Low Records
The “HIGH” and “LOW” temperature records are automatically cleared
every 24 hours. The time records clear each day is determined by the time the
battery was installed. For example, if the battery was installed at 6:00 pm,
then high/low records will reset at 6:00 pm daily.
Care & Maintenance
Clean with a soft, damp cloth. Do not use caustic cleaners or abrasives.
