This manual introduces the Polar WM21/22/41/42 weight‑control watch, its components (heart‑rate sensor, elastic band, and control band) and explains the basic operation of the heart‑rate monitor and weight‑control program. It guides users through creating a personal weight‑control program, setting goals, and logging daily activity and calorie consumption.
The guide also covers navigation of the device menus, updating weight data, using the UpLink function to transfer data, safety precautions, warranty information, and answers to common questions. This manual is written in Chinese.
Use the heart‑rate monitor to input your current weight and set the desired goals; the device will calculate the program and update it automatically.
