This manual explains how to safely set up and use the Omron HEM‑7220 electronic sphygmomanometer. It covers safety warnings, battery handling, power‑adapter use, cuff placement, posture, and step‑by‑step measurement procedures, including automatic memory of results and weekly average calculations.
Additional sections describe how to set the date and time, interpret icons such as morning‑blood‑pressure alerts, perform manual inflation, read stored records, maintain the device, and understand the technical specifications such as pressure range, pulse rate detection, and environmental limits. This manual is written in Chinese.

It appears when the weekly average of morning measurements exceeds the high‑blood‑pressure threshold of 135 mmHg systolic or 85 mmHg diastolic.
No. The manual advises not to use the device on moving transportation such as cars or airplanes because measurements may be inaccurate.
