Key features include:

• Simultaneous display of current, minimum, and maximum temperatures.
• Real-time and date stamp with a 10-second refresh rate.
• Accuracy of ±0.5°C and a 0.1° display resolution.
• Large digits for quick and easy readings.
• Audible alarm for programmable low and high temperature limits.
• Multiple mounting options: fold-away stand, magnet, and hook-and-loop attachments.

Setup Instructions

1. Unpacking: Carefully remove the thermometer and its accessories from the packaging. Inspect for any damage.
2. Battery Installation: The thermometer typically comes with batteries pre-installed or requires 1 AAA battery. Open the battery compartment on the back of the unit and insert the battery, ensuring correct polarity (+/-). Close the compartment securely.
3. Probe Placement: The external probe is designed to be placed inside the refrigerator or freezer. Ensure the probe cable is not pinched by the door seal. The probe is encased in a bio-safe glycol bottle, which buffers temperature fluctuations for more accurate readings of stored items.
4. Initial Power-On: The device should power on automatically once batteries are installed. The display will show current, minimum, and maximum temperatures.
5. Mounting: Choose a suitable location for the main unit. Use the integrated fold-away stand for tabletop use, the magnet for metal surfaces, or the hook-and-loop attachment for other surfaces.

2. Switching Temperature Units (°F/°C):

   Press the Mode button to toggle between Fahrenheit (°F) and Celsius (°C) temperature units.

3. Setting Alarms (High/Low Limits):

   The thermometer features programmable high and low temperature alarms. Refer to the detailed instructions below for setting these limits:

   • Press and hold the Mode button until the alarm setting mode is activated.
   • Use the Min-Reset LO↓ and Max-Reset HI↑ buttons to adjust the desired low and high temperature limits.
   • Press Mode again to confirm each setting and move to the next.
   • An audible alarm will sound if the temperature breaches these set limits.
4. Resetting Min/Max Readings:

   To clear the recorded minimum and maximum temperatures:

   • Press the Min-Reset LO↓ button to reset the minimum temperature.
   • Press the Max-Reset HI↑ button to reset the maximum temperature.

Maintenance

• Cleaning: Wipe the thermometer unit and probe with a soft, damp cloth. Do not immerse the main unit in water. Use mild soap if necessary, then wipe with clean water and dry thoroughly. Avoid abrasive cleaners or solvents.
• Battery Replacement: When the display dims or becomes erratic, it's time to replace the battery. Open the battery compartment on the back, remove the old battery, and insert a new AAA battery, observing polarity. Dispose of old batteries responsibly.
• Probe Care: Ensure the probe cable is not kinked or damaged. The glycol bottle surrounding the probe is sealed; do not attempt to open it.
• Storage: If storing the thermometer for an extended period, remove the battery to prevent leakage. Store in a cool, dry place away from direct sunlight and extreme temperatures.
