5. Safety Information and Precautions

  • If the display indication becomes blurry, replace the batteries promptly.
  • Do not place this product in hot, humid, dusty environments, or areas with corrosive gases, as this may damage its electronic components.
  • The temperature alarm will not activate immediately upon exceeding a preset value. It will compare the temperature after a 10-minute interval. If the temperature remains outside the set range after this period, the alarm will sound. This delay prevents false alarms from brief door openings.

6. Setup

6.1 Battery Installation

Main Unit: Open the battery compartment on the back of the main unit. Insert 2 x AAA batteries, ensuring correct polarity (+/-). Close the compartment.

Remote Sensors: Open the battery compartment on the back of each remote sensor. Insert 2 x AA batteries into each sensor, ensuring correct polarity (+/-). Close the compartment.

6.2 Sensor Placement

Place the remote sensors in your desired monitoring locations, such as inside a refrigerator, freezer, or outdoors. The sensors can be attached using their integrated clips or hanging holes.

6.3 Main Unit Placement

Position the main display unit in a convenient location within its transmission range (up to 100m in open air). It can be:

  • Standing: Use the integrated kickstand to place it on a table or countertop.
  • Hanging: Use the hanging hole to mount it on a wall.
  • Magnetic: Attach it to a metallic surface, such as a refrigerator door, using the built-in magnets.

7.2 Basic Operation

  • Temperature Unit Selection: Press the "+/°C/°F" button to switch between Celsius (°C) and Fahrenheit (°F).
  • View Min/Max Records: The display automatically cycles through current, maximum (MAX), and minimum (MIN) temperatures for each channel.
  • Clear Min/Max Records: Press the "CLEAR" button to reset the recorded maximum and minimum temperatures for all channels.

7.3 Setting Temperature Alarms

The device allows you to set high and low temperature alarms for each sensor channel (Sensor 1, Sensor 2, and Indoor).

  1. Press the corresponding "ALARM SENSOR1", "ALARM SENSOR2", or "ALARM INDOOR" button to select the channel you wish to set an alarm for.
  2. While the alarm setting is active for a channel, use the "+/°C/°F" and "-" buttons to adjust the desired high and low temperature thresholds.
  3. Press the alarm button again to confirm the settings and activate the alarm for that channel. The alarm icon will appear on the display.
  4. To deactivate an alarm, press the corresponding alarm button until the alarm icon disappears.

8. Maintenance

  • Cleaning: Wipe the device and sensors with a soft, damp cloth. Do not use abrasive cleaners or immerse in water.
  • Battery Replacement: Replace batteries when the low battery indicator appears on the display or if the display becomes blurry. Ensure to use the correct battery types (AAA for main unit, AA for sensors).
  • Storage: If storing the device for an extended period, remove all batteries to prevent leakage.

9. Troubleshooting

ProblemPossible CauseSolution
No display or blurry displayLow or dead batteries; incorrect battery installation.Replace batteries with new ones, ensuring correct polarity.
No temperature reading from a sensorSensor out of range; sensor batteries low/dead; interference.Move sensor closer to the main unit; replace sensor batteries; reduce sources of interference (e.g., large metal objects).
Inaccurate temperature readingsSensor exposed to direct heat/cold; sensor not properly calibrated (unlikely for this type of device).Ensure sensors are placed in a representative area; compare with another known accurate thermometer.
Alarm not soundingAlarm not activated; alarm thresholds set too wide; 10-minute delay not passed.Ensure alarm is activated for the specific channel; adjust alarm thresholds; wait for the 10-minute delay to pass.
