Frequently Asked Questions - SL257 LIVOO
How do I turn on the thermometer?
Press the power button (usually marked with a circle or 'ON'). The LCD screen will display the last measurement and then show 'L°C' or 'L°F' indicating ready.
How do I switch between Celsius and Fahrenheit?
While the thermometer is off, press and hold the power button for 3 seconds until the unit flashes. Then press the button again to switch. Confirm by letting it beep.
What does the fever alarm mean?
If the temperature is above 37.5°C (99.5°F), the device will emit a series of short beeps to indicate a possible fever. For higher temperatures (usually >38°C), the beeping may be faster.
How do I clean the thermometer?
Use a soft cloth dampened with 70% isopropyl alcohol or warm soapy water to wipe the tip. Do not immerse the entire unit in water or use abrasive cleaners.
How long does the battery last?
The CR2032 battery typically lasts for about 2000 measurements or 1 year under normal use. Replace when the display is dim or shows 'Low Battery'.
Where can I get a replacement battery?
CR2032 batteries are widely available at electronics stores, supermarkets, and online retailers. Open the battery compartment (usually on the back) with a small screwdriver if needed.
Is the thermometer waterproof?
The tip is water-resistant for cleaning purposes, but the entire device is not waterproof. Do not submerge it in water or use it in the shower.
Why does the display show 'Lo' or 'Hi'?
'Lo' means the measured temperature is below 32.0°C (89.6°F) – the sensor may not be placed correctly. 'Hi' means above 42.9°C (109.2°F) – remove and let cool.
How do I know if the measurement is accurate?
Ensure the sensor tip is in full contact with the skin (for underarm) or under the tongue (oral). Wait for the final beep. The device is calibrated at factory; no user calibration needed.
Can I use the thermometer for children?
Yes, but supervision is required. For children under 3, use the rectal method (with a clean tip). The fever alarm is helpful for monitoring.
