The main unit is powered by 3x AAA batteries, and each sensor by 2x AAA batteries (batteries not included).

Setup Guide

1. Battery Installation

For the Main Display Unit:

1. Open the battery compartment cover on the back of the main unit.
2. Insert 3 AAA batteries (not included) according to the polarity markings (+/-).
3. Close the battery compartment cover.

For the Wireless Sensors:

1. Open the battery compartment cover on the back of each sensor.
2. Insert 2 AAA batteries (not included) into each sensor according to the polarity markings (+/-).
3. Close the battery compartment cover. The sensor's LED indicator will flash once, indicating it is transmitting data.

Note: Use fresh alkaline batteries for optimal performance, especially in low temperatures. Rechargeable batteries are not recommended.

2. Sensor Pairing

The main unit should automatically connect to the sensors once batteries are installed. If a sensor does not connect, or if you need to re-establish connection:

1. Ensure both the main unit and the sensor are powered on and within range.
2. On the main unit, press the "CH/+" button to select the desired channel (1 or 2) for the sensor you wish to reconnect.
3. Press and hold the "CH/+" button for approximately 3 seconds. The main unit will attempt to reconnect to the selected sensor. The signal icon for that channel will flash until a connection is established.

3. Sensor Placement

Place the wireless sensors in the desired monitoring locations, such as inside a refrigerator, freezer, or other indoor areas. The sensors are designed to withstand cold temperatures.

Sensors also have hang holes for wall mounting or can be placed on shelves. The image shows the battery compartments and stand on the back of the main unit and a sensor.

Operating Instructions

1. Power On/Off

The main unit and sensors power on automatically once batteries are installed. There is no manual power on/off button for the sensors. To turn off the main unit, remove its batteries.

2. Temperature Unit Selection (°C/°F)

To switch between Celsius (°C) and Fahrenheit (°F), locate the °C/°F switch inside the battery compartment of the main unit. Slide the switch to your preferred unit.

3. Backlight Function

Press any button on the main unit to activate the backlight for approximately 10 seconds, improving readability in low-light conditions.

4. Setting Temperature Alarms (MAX/MIN)

The thermometer allows you to set upper (MAX) and lower (MIN) temperature limits for each channel. An audible alarm will sound if the temperature goes outside these set limits.

1. Press and hold the "ALARM" button for 3 seconds. The MAX alarm value will flash.
2. Use the "CH/+" or "CLEAR/-" buttons to adjust the MAX temperature limit.
3. Press the "ALARM" button again to confirm the MAX setting and proceed to the MIN alarm setting. The MIN alarm value will flash.
4. Use the "CH/+" or "CLEAR/-" buttons to adjust the MIN temperature limit.
5. Press the "ALARM" button once more to confirm the MIN setting and exit alarm setting mode. The display will return to normal operation.

5. Viewing MAX/MIN Records

The main unit records the maximum and minimum temperatures detected by each sensor and its own ambient sensor.

• In normal mode, press the "MAX/MIN" button once to display the maximum recorded temperatures for all channels.
• Press the "MAX/MIN" button again to display the minimum recorded temperatures for all channels.
• Press the "MAX/MIN" button a third time to return to the current temperature display.

6. Clearing MAX/MIN Records and Switching 24H/ALL TIME

To clear the MAX/MIN records or switch between 24-hour and all-time records:

• In normal mode, press and hold the "CLEAR/-" button for 3 seconds. This will clear the MAX/MIN records and switch the display between 24-hour and all-time recording modes.

Maintenance

Cleaning:

• Wipe the main unit and sensors with a soft, damp cloth.
• Do not use abrasive cleaners or solvents.
• Ensure the devices are completely dry before re-installing batteries or placing them in use.
