3. Product Features

• Wide Range & High Accuracy: The thermometer features a 3-channel system with three transmitters for monitoring temperature and humidity in multiple locations. It offers an indoor temperature range of 0°C to 60°C (32°F to 140°F) and an outdoor temperature range of -40°C to 60°C (-40°F to 140°F). Humidity is measured from 10% to 99%. Accuracy is ±1°C (±1.8°F) for temperature and ±5% for humidity. The wireless transmission range between the main unit and sensors is up to 100 meters (328 feet).
• Max & Min Record: The device records maximum and minimum temperature and humidity values for the main unit and all three remote sensors. Data updates every 60 seconds. Users can switch between Celsius and Fahrenheit display modes. The main unit also includes time, alarm clock, calendar, and snooze/light functions.
• Clear LCD Screen: The LCD screen provides clear readability. A humidity comfort indicator uses smiley icons to represent environmental conditions: 'DRY' for humidity below 45%, 'COMFORT' for humidity between 45% and 65%, and 'WET' for humidity above 65%.
• Backlight Function: The display features a backlight for enhanced visibility in low-light conditions. Pressing the backlight button activates the illumination, which automatically turns off after 5 seconds.
• Easy to Operate: The main unit can be placed on a surface using its integrated stand or mounted on a wall. Each remote sensor also supports wall mounting or standing. The main unit requires 3 AAA batteries, and each sensor requires 2 AAA batteries (batteries not included). A low battery indicator will appear on the display when sensor batteries need replacement.

4. Setup

4.1 Battery Installation

1. Main Unit: Open the battery compartment on the back of the main unit. Insert 3 AAA batteries, ensuring correct polarity (+/-). Close the compartment.
2. Remote Sensors: Open the battery compartment on the back of each remote sensor. Insert 2 AAA batteries into each sensor, observing correct polarity. Close the compartments.

Note: Batteries are not included and must be purchased separately.

4.2 Sensor Pairing

After battery installation, the main unit will automatically begin searching for sensor signals. The receiving icon on the main unit will flash. To pair the sensors:

1. Ensure all sensors have batteries installed and are powered on.
2. The main unit will attempt to connect to the sensors for approximately 3 minutes.
3. If a sensor does not connect automatically, press the 'CHANNEL' button on the main unit to cycle through channels until the desired sensor's data appears.
4. For manual re-pairing, press and hold the 'CHANNEL' button on the main unit until the receiving icon flashes again, then press the 'TX' button inside the battery compartment of the remote sensor you wish to pair.

4.3 Placement Options

The main unit and remote sensors offer flexible placement:

• Main Unit: Features an integrated kickstand for desktop placement and a mounting hole for wall hanging.
• Remote Sensors: Can be placed on a flat surface, mounted on a wall, or hung using the integrated hook.

6. Maintenance

6.1 Battery Replacement

When the low battery indicator appears on the main unit's display for a specific sensor, it is time to replace the batteries for that sensor. For the main unit, replace batteries when the display dims or functions become erratic.

1. Open the battery compartment.
2. Remove the old batteries.
3. Insert new AAA batteries, ensuring correct polarity.
4. Close the battery compartment.

Always dispose of used batteries responsibly according to local regulations.

7. Troubleshooting

If you encounter issues with your AMIR thermometer, refer to the following common problems and solutions:

• No Reading from Remote Sensor:
  • Check if the sensor batteries are installed correctly and are not depleted. Replace if necessary.
  • Ensure the sensor is within the 100m (328ft) transmission range of the main unit.
  • Reduce obstacles between the sensor and the main unit (e.g., thick walls, electronic devices).
  • Re-pair the sensor by pressing the 'CHANNEL' button on the main unit and the 'TX' button on the sensor.
• Inaccurate Readings:
  • Ensure sensors are not exposed to direct sunlight, rain, or extreme temperature fluctuations.
  • Place sensors away from heat sources or vents.
  • Allow the devices to stabilize for 15-30 minutes after initial setup or relocation.
• Display is Dim or Blank:
