Hold the MODE key for 3 seconds to enter High Alarm temperature setting mode. Use the up and
down arrows to adjust temperature accordingly.
Press MODE key ONCE to confirm the setting.
Low Alarm Temperature Setting
This is the low temperature limit. The current temperature is considered out-of-range if
the probe reads a temperature equal to or below the low temperature limit.

Battery Life
The unit comes with a rechargeable lithium battery. In case of power failure the average battery life is about 20 hours when fully charged.
To achieve longer battery life during operation, use a less frequent sample rate.
Set the high and low alarm temperature limits above and below the refrigerator/freezer operating temperature to prevent
false alarms. Refrigerators are designed to run between 2-8 °C (36-46 °F) while freezers run below -15 °C (5 °F).
