Frequently Asked Questions - BDT-2978 Becken
How should I measure my temperature with the Becken BDT-2978?
Place the probe under your tongue (oral), in the rectum (rectal), or in the armpit (axillary). Press the on/off button, wait for the beep, and read the display. For best accuracy, keep your mouth closed during oral measurement.
What does the fever beep mean?
A continuous beep or a special alarm sound indicates a fever when the measured temperature is above 37.8°C (100°F). Normal readings produce a single short beep.
How long does it take to get a reading?
The BDT-2978 typically gives a reading in about 60 seconds. The actual time may vary slightly depending on the measurement site and the person's condition.
How do I replace the battery?
Slide the battery cover on the back of the thermometer open using a small screwdriver. Remove the old LR41 button cell, insert a new one with the positive (+) side facing up, and close the cover securely.
Can I use this thermometer on babies?
Yes, the BDT-2978 is safe for newborns and infants, but we recommend rectal measurement for the most accurate temperature in babies under 3 months. Always clean the probe thoroughly before and after use.
How do I clean the thermometer?
Use a soft cloth dampened with 70% isopropyl alcohol to wipe the probe and the body. Never immerse the thermometer in water or use harsh cleaning agents, as this can damage the electronics.
What is the accuracy of this thermometer?
The BDT-2978 is accurate to ±0.1°C (0.2°F) within the range of 35°C to 42°C. This meets the requirements for clinical use according to ASTM standards.
Why does the display show 'Lo' or 'Hi'?
'Lo' indicates the temperature is below 32.0°C (89.6°F), and 'Hi' indicates it is above 42.9°C (109.2°F). This usually means the probe was not placed correctly or the ambient temperature is too extreme.
Does the thermometer have a memory function?
Yes, the BDT-2978 automatically stores the last reading in memory. When you turn it on again, the previous temperature is displayed for a few seconds before the device is ready for a new measurement.
Is this thermometer waterproof?
No, it is only splash proof (IP22). Do not submerge it in water or expose it to heavy moisture. For cleaning, use a damp cloth with alcohol instead of rinsing under a tap.
