is very important.Because the blood pressure of the human body is constantly
changing on the same day, it is recommended that you set the correct date and
time immediately after installing the battery.Please set the correct date and time
as following,(Example: enter time and day -12:01 pm. on Aug. 28th )
1. In power off mode, press and hold the [START/STOP] key and the [MEM] key
for about 3 seconds at the same time, and the product will enter the function
setting mode (if not selected, the system defaults to the factory year). The
last two digits of the year will flash on the screen. You can enter the year by
pressing the [MEM] button. For example, the default year is 20: press once to
increase the year from 20 to 21.
2. Press the [START/STOP] button again, and there will be a jump of the month
in the left corner of the screen. At this time, the first digit of the month starts
to flash. You can enter the month by pressing the [MEM] button (for example,
you can increase the month from January to 8 months by pressing 7 times).
