How to set an alarm in a perpetual calendar

This mainly depends on the specific model of the electronic calendar. I recommend the alarm clock setting method for general electronic calendars for reference: 1, time setting: A- date and time setting/moving the alarm clock switch on the hour/adding C- changing the pattern of solar energy-saving lamps/reducing D-.

Press the "A" key, and the "Year" flashes; Press the "b" or "c" key to set it to "20 10" year; Press the "A" key again, and the "Moon" flashes; Press the "b" or "c" key to set it to "1" month; Press the "A" key again, and the "Day" flashes. Press the "B" or "C" key to set it as "28th" day; Press the "A" key again, and the "hour" flashes. Press the "B" or "C" key in the morning and set it to "10"; Press the "A" key again, and the "Minute" flashes. Press the "B" or "C" key to set it to "38" minutes; Press the "A" key again, and the "second" will flash; Press the "B" or "C" key, and seconds will be counted from 00; (Note: This step is not displayed when there is no second digital tube. Press the "A" key again to exit the time setting. 2. Alarm setting: Press the "D" key to enter the alarm setting, and the alarm serial number will be displayed and flashed at the position of the month digital tube. Press "B" or "C" to select one of the settings of alarm 1 ~ 4; Blink when pressing the "D" key again, and press the "B" or "C" key to adjust to the set value; Press the "D" key to flash again, and press the "B" or "C" key to adjust to the set value; Press the "D" key again, and the alarm state of "On" or "-"will be displayed and flashed at the position of the day digital tube. Press "B" or "C" to turn off or turn on the alarm, and then press "D" to exit the alarm setting. Note: As long as 1 or 1 of the four alarms is set to ON, the alarm indicator lights up, and only when all alarms are turned off will the alarm indicator lights go out. 3. Hourly alarm setting: During normal operation, press the "B" key, and the alarm indicator on the panel will light up, indicating that the hour alarm has been turned on, otherwise the light will go out.
