How to adjust the time of electronic perpetual calendar?

The method of adjusting the time is as follows:

1. The button for adjusting time is on the back. Turn over the perpetual calendar.

2. There are four buttons in the lower left corner of the back.

3. Click the button next to "Settings" with a double arrow on it.

4. When you press it, the year number of the electronic clock will start flashing. When the flashing number disappears, Bian Xiao will take photos.

5. Press it again, and it will be the turn of the month to flash. In this way, the year, month, day and time are selected in turn. Press that number to change and start flashing. What Bian Xiao wants to change is the "minute" in an hour.

6. Then press the "+"key, which says "Modify/Alarm" next to it. (Pressing the "+"key can only add, but not subtract, just like if my 59 is changed to 49, I can only add 60, 1, 2, 3 ...)

7, so the adjustment, adjustment date or day of the week is also the same adjustment method.
