The Rossmax TG100 Thermometer comes with a pre-installed LR44 battery. Before first use, ensure the battery compartment is securely closed. If the display does not turn on or shows a low battery indicator, replace the battery as described in the "Maintenance and Care" section.

Initial Power-On:

1. Press the power button (usually located near the display) to turn on the thermometer.
2. A short beep will sound, and the display will briefly show all segments, followed by the last measured temperature.
3. The device will then display "Lo" and a flashing "°C" or "°F", indicating it is ready for measurement.

4. Operating Instructions

Taking a Temperature Measurement:

1. Clean the Probe: Before and after each use, clean the thermometer probe with alcohol or soap and water.
2. Power On: Press the power button. The thermometer will display the last reading and then "Lo" with a flashing unit symbol.
3. Positioning:
   • Oral Use: Place the probe tip under the tongue, as close to the heat pocket as possible. Keep the mouth closed.
   • Underarm (Axillary) Use: Place the probe tip in the center of the armpit. Hold the arm firmly against the body.
4. Measurement: Keep the thermometer in position until a series of beeps indicates the measurement is complete (approximately 60 seconds). The display will show the peak temperature.
5. Read the Result: Read the temperature displayed on the LCD screen.
6. Power Off: Press the power button to turn off the thermometer, or it will automatically shut off after approximately 10 minutes of inactivity.
