4. Setup
4.1 Battery Installation
- Main Display Unit: Open the battery compartment on the back. Insert 2 AAA batteries, observing polarity. Alternatively, connect the main unit using the provided USB cable for continuous power and backlight.
- Wireless Sensors: Open the battery compartment on each sensor. Insert 2 AAA batteries into each sensor, observing polarity.
4.2 Pairing Sensors
The main unit and sensors should automatically pair upon battery installation. If pairing does not occur or is lost:
- Ensure both the main unit and sensors have fresh batteries.
- Place the sensors close to the main unit.
- On the main unit, long press the /RF button to initiate re-pairing. The screen will display the alarm symbol. Press again to clear previous connection data and re-scan.
5. Operating Instructions
5.1 Button Functions (Rear of Main Unit)
- CH1 Button:
- Short press: Toggle CH1 alarm ON/OFF. An alarm symbol appears when active.
- Long press: Set CH1 alarm temperature (maximum and minimum values). Use +/- buttons to adjust. Configurable range: -40°C to 60°C (-40°F to 140°F).
- CH2 Button:
- Short press: Toggle CH2 alarm ON/OFF. An alarm symbol appears when active.
- Long press: Set CH2 alarm temperature (maximum and minimum values). Use +/- buttons to adjust. Configurable range: -40°C to 60°C (-40°F to 140°F).
- +/MEM Button:
- Short press: Switch between 24H and ALL TIME logging modes to display highest and lowest recorded values.
- Long press: Clear the history protocol for the currently displayed mode.
- /RF Button:
- Short press: Display the set alarm values for both channels (alarm symbol appears). Default values are 60°C (max) and -40°C (min).
- Long press: Re-pair the screen with sensors. Press again to remove previous connector data and initiate a new scan.

- Backlight:
- Battery mode: Short press to turn on the backlight for 8 seconds (automatic shutdown to save energy).
- USB mode: Short press to toggle the backlight ON/OFF. When ON, it stays illuminated.
- Temperature Unit (°C/°F): Long press for 2 seconds to switch between Celsius (°C) and Fahrenheit (°F).
5.3 Alarm Function
When the temperature measured by a sensor exceeds the set maximum or falls below the set minimum, the device will trigger a continuous audible alarm and the backlight will flash red. This provides an immediate warning to protect stored items.

6. Features
- Dual Channel Monitoring: Equipped with two independent wireless sensors to simultaneously monitor temperatures in two separate locations (e.g., fridge and freezer).
- Clear Color Display: A 3.42-inch color screen with white backlight ensures easy readability of all data, even in low light conditions.
- Adjustable Temperature Alarm: Set custom high and low temperature alarms for each sensor. An audible alarm and flashing red backlight activate if temperatures exceed or fall below these thresholds.
- Max/Min Temperature and Humidity Records: Displays the highest and lowest recorded temperatures and humidity for the last 24 hours or since the last reset.
- Indoor Monitoring: The main unit also monitors the ambient indoor temperature (-10°C to 60°C / -14.2°F to 140°F) and humidity (10% to 99% RH) where it is placed.
- Wide Outdoor Temperature Range: Wireless sensors monitor temperatures from -40°C to 60°C (-40°F to 140°F).
- Stable Wireless Transmission: Provides a stable wireless range of up to 100 meters (328 feet) in open areas.
- Dual Power Supply: The main unit can be powered by 2 AAA batteries or a USB cable. Sensors are powered by 2 AAA batteries each.
- Low Battery Warning: Indicates when batteries are running low.
7. Placement and Installation
Main Display Unit
The main unit offers multiple placement options:
- Stand: Use the integrated foldable stand for tabletop placement.
- Wall Mount: Utilize the hang hole on the back to mount it on a wall.
- Magnetic Attachment: The magnetic back allows attachment to metallic surfaces, such as a refrigerator door.
Wireless Sensors
Place the wireless sensors in the desired monitoring locations, such as inside a refrigerator or freezer. Ensure they are positioned to avoid direct contact with food or ice, which could affect readings. The sensors also have a hang hole for wall mounting.

9. Troubleshooting
- No Display/Low Battery: Check battery installation and replace with fresh AAA batteries. If using USB power for the main unit, ensure the cable is securely connected.
- Sensors Not Connecting: Ensure sensors are within range (up to 100m in open areas, less with obstructions). Re-pair by long pressing the /RF button on the main unit.
- Inaccurate Readings: Ensure sensors are not in direct contact with cold surfaces or food, which can affect readings. Allow time for temperatures to stabilize after placement.
- Alarm Not Functioning: Verify that the alarm is enabled for the respective channel (CH1/CH2) and that the alarm thresholds are set correctly.
- Backlight Issues: In battery mode, the backlight turns off after 8 seconds to save power. For continuous backlight, use USB power.
