How to set an alarm in a perpetual calendar

This mainly depends on the specific model of the electronic calendar. I recommend the alarm setting method of the universal electronic calendar for reference: 1, time setting: A- date and time setting/move B- turn on the hour switch/add C- change the pattern of the solar term lamp/reduce D-.

Press the "A" key, and the "Year" flashes; Press "b" or "c" to set it to "20 10" year; Press the "A" key again, and "Month" flashes; Press "b" or "c" 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" will flash. 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 to start counting 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 position of the day digital tube will display and flash the alarm state of "On" or "-". 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 over 1 of the four alarms is set to ON, the alarm indicator will light up, and only when all alarms are turned off will the alarm indicator light go out. 3. Setting of the hourly alarm: During normal operation, press the "B" key, and the alarm indicator on the panel will be "ON" to indicate that the hourly alarm has been turned on, otherwise the indicator will be "OFF" to indicate that it has been turned off.
