Use

First, remove the protective foil from the display. For switch on, briefly press the on/off key. A short acoustic signal will announce that the thermometer is switched on. The thermometer will carry out a self-test for about 2 seconds. During the self-test, all segments of the display will appear. Then the reference reading (37 °C) appears. Next, the measurement symbol “°C” flashes and “Lo” is shown on the display. The thermometer is now ready for use. During the measurement, the current temperature is displayed continuously, and the “°C” symbol flashes on and off. The measurement is completed when a stable temperature has been reached. At this stage, an acoustic signal is heard, the “°C” symbol stops flashing, and the measured temperature is displayed. As long as the measured temperature is below 32 °C, “Lo °C” will appear. Higher temperatures will be shown directly, e.g., 32.1 °C. By prolonging the measurement beyond the acoustic signal, more accurate measurements can be obtained. When measuring the temperature in the armpit, the thermometer should remain in place for the recommended measurement time, despite the acoustic signal. If temperatures over 37.8 °C are measured, a fever alarm sounds (short bleeping tones lasting 10 seconds). If temperatures higher than 42.9 °C are measured, the symbol “Hi °C” will appear. To prolong the battery life, switch off the thermometer by briefly pressing the on/off key after the measurement. Otherwise, the thermometer will automatically switch off after 10 minutes.

Memory

The last measured value will be stored automatically. Press the on/off button to display this value. The thermometer first carries out a self-test. Next, the last stored measured value is displayed for approximately 2 seconds. Then the reference value of 37 °C and “Lo” are shown on the display. The thermometer is ready to take a measurement, and the previously stored measurement value is automatically replaced by the new measurement value.

Changing the battery

The clinical thermometer contains a long-lasting alkali-manganese battery (type LR41, 1.5 V) with an approximate service life of 2 years. The battery needs to be replaced when all digital readings appear flashing on the display screen. Release the battery compartment cover by gently pressing on the catch. Remove the old battery and replace it with a battery of the same type. The + sign on the battery must point upwards. Then close the battery compartment, making sure that the catch clicks into place. Empty, completely flat batteries must be disposed of through specially designated collection boxes, recycling points, or electronics retailers. You are legally required to dispose of batteries properly. The codes below are printed on batteries containing harmful substances:

• Pb = Battery contains lead.

Troubleshooting the Beurer FT 09/1 Thermometer: Common Issues and Fixes

Encountering problems with your Beurer FT 09/1 Thermometer? Start with basic checks: Ensure the battery is inserted correctly (1 x LR41) and is not low—replace it if the indicator shows. If no display appears, press the power button; "Lo" followed by flashing °C indicates readiness.

• No acoustic signal or incomplete reading: Measurement takes ~30 seconds; wait for stability. Clean the waterproof tip with disinfectant and dry thoroughly.
• Error in readings (e.g., outside 32-42.9°C range): Verify ambient temperature (18-28°C for optimal ±0.1°C accuracy); reposition for oral/rectal/axillary use.
• Blinking °C or "Lo" persists: Battery issue or improper contact—replace battery and ensure snug fit.

Prevent issues by storing with protective cap, avoiding drops, and disinfecting post-use. No specific error codes are listed, but contact Beurer support for anomalies. Enjoy 5-year warranty coverage; register at beurer.com.
