Function key description:

S1 is the function selection button and the role of shift, S2 is the confirmation function, S3 is an increase in value.

 
Function adjustment instructions:
 
1. Clock function:
If it is the clock of the internal timer of the chip, it will display 00:00:00 after power-on (the time will not be saved after power off, and the time of re-powering will return to 0);
If it is a set of external clock DS1302, after power on, will display the internal time of the chip (this time can be kept walking after power-off, and the current time is displayed from the new power-on);
2. Calibration time function: Press S1 once, the digital tube displays SET1 (setting time), then press S2 once to enter the modification time, the digital tube displays 00:00, the ten-digit flashing (seconds is not adjustable), press again S1 can move the flashing position, press once to move one bit, press S3, the corresponding flashing position will increase by 1. After setting, press S2 again to save and exit.
3. Alarm function: press S1 twice, the digital tube displays SET2 (set alarm), then press S2 once to enter the modify alarm clock, the digital display shows 00:00 0 (the second digit is not adjustable, the latter 0 means the status of the alarm clock, 0 means the alarm is off, 1 means the alarm is on). Press S1 again to move the flashing position. Press once to move one bit. When pressing S3, the corresponding flashing position will increase 1, press S2 to save and exit.
4. Countdown function: press S1 three times, digital display SET3 (set countdown), then press S2 once to enter the modify countdown, the digital display 00:00:00, the hour flashes, press S1 again to move the flashing position, press once to move one digit. When pressing S3, the corresponding flashing position will increase 1. After setting, press S2 again and the system will start counting down.
5. Stopwatch function: press S1 four times, the digital tube displays SET4 (stopwatch function), then press S2 once to enter stopwatch function, this time S2 is used to open or close the stopwatch, press S3 to exit the stopwatch function.
6. Counter function: press S1 five times, the digital tube displays SET5 (counter function), then press S2 once to enter the counter, press S3 counter value increase 1, press S2 again to exit the counter, the system recovers.
