4. Setup Instructions

4.1 Powering the Main Unit

The main unit can be powered by either AAA batteries or via the included USB cable.

• Battery Power: Open the battery compartment on the back of the main unit and insert 3 x AAA batteries (not included), ensuring correct polarity.
• USB Power: Connect the provided USB cable to the DC 5V port on the main unit and to a USB power source (e.g., USB adapter, computer USB port).

4.2 Powering the Wireless Sensors

Each wireless sensor requires 2 x AA batteries (not included).

1. Open the battery compartment on the back of each sensor.
2. Insert 2 x AA batteries into each sensor, observing the correct polarity.

4.3 Sensor Placement

Place the remote sensors in your desired monitoring locations, such as inside a refrigerator, freezer, or outdoors. Ensure the sensors are within the transmission range of the main unit (up to 30m/98.4ft in open areas, actual range may vary due to interference).

5. Operating Instructions

5.1 Temperature Display and Unit Switching

The main unit displays indoor temperature and the temperatures from Sensor 1 and Sensor 2. To switch between Celsius (℃) and Fahrenheit (℉), press the "UP ℃/℉" button (labeled 4 in Figure 2).

5.2 Setting Temperature Alarms

The thermometer features an audible alarm that activates when temperatures exceed or fall below preset limits. You can set independent high and low alarm values for indoor, Sensor 1, and Sensor 2 readings.

1. Press the "ALARM INDOOR", "ALARM SENSOR1", or "ALARM SENSOR2" button to select the channel for which you want to set the alarm.
2. Use the "UP ℃/℉" and "DOWN" buttons to adjust the maximum (MAX) and minimum (MIN) alarm values.
3. Press the corresponding "ALARM" button again to confirm the setting and activate the alarm for that channel.
4. To turn the alarm alert on/off at any time, press and hold the respective "ALARM" button.

5.3 Max/Min Temperature Record

The device automatically records the maximum and minimum temperatures for each channel (indoor, Sensor 1, Sensor 2) since the last reset. To clear these records, press the "CLEAR" button (labeled 6 in Figure 2).

5.4 Temperature Trend Indicator

The display shows an up, down, or parallel arrow next to each temperature reading to indicate the trend of the current temperature (rising, falling, or stable).

6. Maintenance

• Battery Replacement: When the display becomes blurry or the low battery indicator appears, replace the batteries in the main unit and/or sensors.
• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or immerse the unit in water.
• Storage: Store the thermometer in a cool, dry place away from direct sunlight and corrosive gases.
• Avoid Disassembly: Do not attempt to disassemble the product, as this may damage electronic components and void the warranty.

7. Troubleshooting

• No Display/Blurry Display: Check battery installation and replace with fresh, high-quality batteries if needed. Ensure USB power is connected if using.
• No Sensor Reading: Ensure sensors are powered on and within range of the main unit. Check for any physical obstructions or strong electromagnetic interference.
• Alarm Not Triggering Immediately: The device compares temperature after 10 minutes for initial alarm conditions. Once an alarm value is reached, it will alarm immediately.
• Inaccurate Readings: Ensure sensors are placed in appropriate locations, away from direct heat sources or extreme drafts.

9. User Tips

• Flexible Sensor Placement: The two wireless sensors can be used simultaneously in different locations, such as one in the refrigerator and another in the freezer, or one indoors and one outdoors.
• Optimize Wireless Range: For best wireless transmission, try to minimize physical obstructions (thick walls, metal appliances) between the sensors and the main unit. The stated range of 30m (98.4ft) is for open areas and may be reduced by interference.
• Battery Quality Matters: Using high-quality batteries for both the main unit and the transmitters can improve performance and battery life.
