Frequently Asked Questions

Which measurement method is most accurate — oral, rectal, or underarm?
Rectal temperature measurement is generally considered the most accurate method for core body temperature, particularly for infants and young children. Oral measurement is the most common method for older children and adults. Underarm measurement is the least accurate of the three methods — it typically reads 0.5 to 1 degree Fahrenheit lower than oral temperature — but is the most convenient and least invasive option. Consult your healthcare provider about which method is most appropriate for your situation.

How do I clean the thermometer between uses?
The thermometer is waterproof, which makes cleaning straightforward. Wipe the probe with a cotton ball or swab moistened with rubbing alcohol (isopropyl alcohol 70% or higher) after each use, then rinse with cool water and allow to air dry before storing in the protective case. Do not submerge the entire thermometer in liquid or use hot water. For rectal use, clean the probe thoroughly with alcohol before and after each measurement.

How do I switch between Fahrenheit and Celsius?
The thermometer can be switched between Fahrenheit and Celsius display modes. Refer to the included user manual for the specific button sequence to toggle between temperature scales. The selected scale is retained in memory until changed again.

What does the memory function do?
The thermometer stores the last temperature reading in memory so it can be recalled after the measurement session ends. To recall the last reading, turn on the thermometer — the previous reading will typically display briefly before the device enters measurement mode. Refer to the user manual for the specific memory recall procedure for this model.
