- Slide or open the cover.
- Insert two (2) AA batteries, ensuring correct polarity (+ and -).
- Close the battery compartment cover securely.
The thermometer requires 2 AA batteries for operation.
Operating Instructions
Taking a Measurement (Body Temperature)
- Ensure the thermometer is in Body Measurement mode (indicated by a human head icon on the display). If not, refer to the "Switching Measurement Modes" section.
- Point the thermometer at the center of the forehead, approximately 1-2 cm away.
- Press the measurement button (often the same as the power button).
- The temperature reading will appear on the display within 1 second.

Switching Measurement Modes (Body/Object)
The URF102 thermometer supports both body and object temperature measurement. Refer to the device's specific buttons (often a dedicated mode button or a long press of the measurement button) to switch between these modes. The display will show a human head icon for body mode and a house/object icon for object mode.

Figure 4: An illustration demonstrating the AlphaMed URF102 thermometer's capability to measure both body and object temperatures. The main image shows the thermometer with a body temperature reading (36.3°C), while smaller inset images show the display in body mode and object mode (32.3°C).
Switching Temperature Units (°C/°F)
The thermometer can display temperatures in Celsius (°C) or Fahrenheit (°F). Typically, this setting can be changed via a dedicated button or by accessing a settings menu (e.g., by holding down a button while the device is off, then pressing it again to cycle through options).
Fever Alarm Function
The URF102 features an alarm function that activates when a temperature reading exceeds 37.5 °C (or 99.5 °F). This is often accompanied by a visual indicator (e.g., a change in backlight color) and an audible beep.
- Normal Temperature: Between 36.5°C and 37.5°C
- Elevated Temperature: Between 37.6°C and 38.5°C
- Fever: Above 38.5°C (High Fever above 39.5°C)

Memory Function
The thermometer can store up to 20 sets of previous temperature readings. To access the memory, typically press a dedicated memory button or cycle through readings using the measurement button when the device is off or in a specific mode. Refer to your device for exact instructions.
Automatic Shut-off
To conserve battery life, the thermometer will automatically shut off after approximately 60 seconds of inactivity.
