5. Setup

1. Battery Installation:
   • Locate the battery compartment on the back of the main unit.
   • Open the compartment cover.
   • Insert the required batteries (e.g., AAA, check compartment for type) ensuring correct polarity (+/-).
   • Close the battery compartment cover securely.
2. Probe Placement:
   • Carefully route the remote temperature probe into the refrigerator or freezer. Ensure the cable is not pinched by the door seal, which could damage the cable or compromise the seal.
   • Place the probe tip in the area where temperature monitoring is desired. Avoid placing it directly against cooling elements.
3. Main Unit Placement:
   • Attach the main unit to the exterior of the refrigerator or freezer using its built-in magnets.
   • Ensure the display is easily visible for regular temperature checks.

6. Operating Instructions

1. Power On/Off:

   The device typically powers on automatically upon battery installation. There may not be a dedicated power button; removal of batteries usually powers it off.
2. Switching Temperature Display (Room/Fridge):

   Press the ROOM/FRIDGE button to toggle between displaying the ambient room temperature (measured by a sensor in the main unit) and the temperature measured by the remote probe (for the fridge/freezer).

3. Viewing MAX/MIN Temperatures:

   Press the MAX/MIN button once to display the maximum temperature recorded since the last reset. Press it again to display the minimum temperature. Press a third time to return to the current temperature display.

4. Resetting MAX/MIN Temperatures:

   While MAX or MIN temperature is displayed, press and hold the MAX/MIN button for a few seconds until the display resets to the current temperature. This clears the recorded high and low values.
5. Alarm Function:

   The device features an alarm. Press the Bell Icon button to activate or deactivate the alarm. If the temperature goes outside a pre-set range, an audible alarm will sound. (Specific instructions for setting alarm thresholds are not available; refer to the device's on-screen prompts or manufacturer's website for advanced settings if applicable).

6. Changing Temperature Units (°C/°F):

   Look for a small switch or button, often located in the battery compartment or on the back of the unit, to switch between Celsius (°C) and Fahrenheit (°F) display.

7. Maintenance

• Cleaning: Wipe the main unit with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water. The probe can be cleaned with mild soap and water, then thoroughly rinsed.
• Battery Replacement: When the display becomes dim or the unit stops functioning, replace the batteries as described in the "Setup" section.
• Storage: If storing the thermometer for an extended period, remove the batteries to prevent leakage.
• Product Care: The product is specified as "Freezer Safe" and "Hand Wash Only" for the probe.
