This is a Omron electronic thermometer. It can measure oral temperature and axillary temperature. The thermometer uses predictive measurement technology to predict how the temperature will change in the next few hours based on the measured temperature data.
This manual explains the components, safety warnings, and step‑by‑step procedures for preparing, measuring body temperature, viewing charts, and using predictive measurement functions of the MC‑440 electronic thermometer. It also covers setting the date, time, alarm, brightness, and restoring factory defaults.
The later sections list technical specifications, battery information, warranty terms, and contact details for service. Appendices include the warranty card, compliance statements, and disposal guidelines for used batteries. This manual is written in Chinese.
