Timer ringing setting
1. Clock adjustment:
While holding down the "clock" button, press the "calibration week" button, "calibration time" button, and "calibration minute" button in sequence to adjust the above time parameters according to the standard.
2. Ring time parameter setting:
2.1. Ring time setting:
Press the "timer" button, and the LCD screen will display "1 on" (the first set of bell setting prompts). You can set the desired time parameters by pressing the "calibration" and "calibration" buttons respectively. After setting the time parameters, set the desired week parameters.
2.2. Weekly parameter settings
Pressing the 'School Week' button will result in the following options:
① Single day setting: (one or two or three... or day)
② One, three, five
③ 246
④ Six days

⑨ One, two, three, four, five, six days
If you need the bell to work every seven days of the week, you can choose option 9, and so on. To reset, press the "Cancel Recovery" button to display the set activation time
3. Ring delay time and interval time settings:
3.1 After setting the "1 on", "2 on"... "20 on" settings, continue to press the "timer" button, and the display screen will show "H10". At this time, you can press the "calibration" button to adjust the ringing delay time (adjustable within 1-99 seconds). If no calibration is performed, it defaults to 10 seconds.
3.2. After the delay time for ringing is set, continue to press the "timer" button, and the display screen will show "45". At this time, you can press the "calibration" button to adjust the ringing interval time (adjustable within 1-99 minutes). If not adjusted, the default ringing interval time is 45 minutes.
After the above settings are completed, press the "clock" button to enter the set working state.
4. When setting the above parameters, if no key is pressed within 30 seconds, the LCD screen will return to standard time. If you continue to set the ringing parameters, you can press the "timer" button again to adjust until the desired parameter position is reached.
4、 Work status display
Work status display:
After the bell chime is connected to the working power supply, the red indicator light for the working indicator will be on. If the bell chime is in working condition, the green indicator light will be on.
5、 Manual bell control
If you need to manually ring the bell temporarily, press the "Manual" button to adjust the LCD screen triangle prompt from "Auto" to "On" position. At this time, the green indicator light for the working status will be on, indicating that the bell is in working condition. To stop the ringing state, press the "Manual" button again to adjust the triangular prompt on the LCD screen from the "On" position to the "Auto" or "Off" position. The ringing delay time can be manually controlled (this ringing time is independent of the set ringing delay time). The triangular prompt must be set to the automatic position during automatic control.

4. You can set up 20 groups and ring the bell 40 times a day;
5. The delay time for ringing the bell is adjustable from 1 second to 99 seconds;
6. The interval between ringing the bell from 1 minute to 90 minutes can be adjusted;
7. Working temperature: -20 ℃ to+60 ℃;
8. Dimensions: 126 × 88 × 51.
7、 Precautions
1. To prevent contact heating under high current, it is necessary to tighten the screws on the wire post when wiring, and keep the working bell away from the ringing device;
2. The input power supply of this bell ringing controller can only be connected to AC220 power supply, do not connect to AC380V power supply;
3. If the bell is not turned on at the scheduled time on a certain day, or if it is turned on but not turned off by the designated time, it may be because the "week" setting for the timer has not been adjusted correctly. Please check or readjust according to the methods described in the timer bell setting;
4. If it is confirmed that the "ringing" start time, ringing delay time, and ringing interval time are all correct, but this switch is turned on when it should not be turned on, or turned off when it should not be turned off at all, please check if the set start time is in order or if there is any overlap in the set time, or if there are several extra ringing times that have not been eliminated (note: the switch time display "" only indicates elimination, do not think "00:00" indicates elimination), you can use the timed ringing setting to eliminate them.
