2. What's in the Box
- 1x Refrigerator Thermometer (Main Unit)
- 2x Wireless Sensors
- 1x User Manual

3. Setup and Installation
3.1 Battery Installation
The main unit requires 3x AAA batteries (not included). Each wireless sensor requires 2x AA batteries (not included). Ensure batteries are inserted with correct polarity.

3.2 Sensor Placement
Place the wireless sensors inside your refrigerator, freezer, or cooler. Ensure they are not obstructed by food items for optimal signal transmission. The main unit can be placed on a table using its integrated bracket, hung on a wall via the hanging hole, or attached to a metallic surface using its magnets.


The transmission range is up to 100 meters (328 feet) in an open area. Walls and other obstructions may reduce this range.
4. Operating Instructions
4.1 Display Overview
The main unit displays temperatures from both wireless sensors (Sensor 1 and Sensor 2) and the indoor temperature of the main unit itself. It also shows maximum and minimum recorded temperatures for each channel over the last 24 hours, along with temperature trend indicators (up, down, or parallel arrow).

4.2 Temperature Range
- Indoor Thermometer Range: -10℃ to 60℃ (14℉ to 140℉)
- Outdoor Thermometer Range: -40℃ to 60℃ (-40℉ to 140℉)
4.3 Switching Between Celsius and Fahrenheit
Press the "+/℃/℉" button on the main unit to toggle between Celsius and Fahrenheit display modes.
4.4 Alarm Function
The thermometer features an audible alarm. You can manually set maximum and minimum alarm values for each sensor. The alarm will sound if the temperature exceeds the set maximum or falls below the set minimum. Note: The alarm function activates 10 minutes after being turned on.

4.5 Max/Min Temperature Records
The unit records the maximum and minimum temperatures for each sensor and the indoor unit over the last 24 hours. These records update daily. To clear the Max/Min values, press the "CLEAR" button.
5. Maintenance
To maintain optimal performance, wipe the units clean with a soft, dry cloth. Avoid using abrasive cleaners or submerging the units in water. Replace batteries when the low battery indicator appears on the display.
6. Troubleshooting
- No Temperature Reading/Sensor Not Connecting:
- Ensure all batteries are correctly installed and have sufficient charge.
- Remove batteries from both the main unit and sensors, wait 30 seconds, then reinsert batteries into the main unit first, followed by each sensor.
- Ensure sensors are within the transmission range (100m/328ft in open area) and not heavily obstructed.
- Allow up to 30 minutes for sensors to register with the main unit after initial setup.
- Alarm Not Sounding:
- Verify that the alarm function is enabled and the maximum/minimum temperature thresholds are set correctly.
- Remember the alarm activates 10 minutes after being turned on.
- Inaccurate Readings:
- Ensure sensors are not placed directly next to cooling vents or heating elements, which can cause localized temperature fluctuations.
- Compare readings with another calibrated thermometer if possible.
