Directions for use:
There is a button on the right side of the watch. The operation process is as follows:
(1) press the button once, it displays time interface with a format as HH (hour) /MM(minute).
(2) press the button again, it displays date interface with a format as DD (day) /MM(month).
It will return to the time interface if you press the button for a third time, and go into a loop.
In most case the watch is in deep sleep, almost with no current consumption.
After each display for 20 seconds, it goes to sleep again.
Time and date switch directions:
The bottom row of the LED on the watch represents the least significant digit.
The values corresponding to rows from bottom to top is: 1,2,4,8.
The time interface displays the columns from left to right in order:
tens digit of hour; units digit of hour; tens digit of minute; units digit of minute.
Take the picture in the upper left for example:
Tens digit of hour: one LED lighting represents 1.
Units digit of hour: two LED lighting represents 1+2=3.
Tens digit of minute: one LED lighting represents 4.
Units digit of minute: three LED lighting represents 1+2+4=7
So the time reading is 13:47.
The date interface shows the order from left to right:
tens digit of day; units digit of day; tens digit of month; units digit of month.
The same way as time reading, the date reading in the upper right picture is 23/08, which means 23rd, August.
