User Manual for Electronic Lock

I. Initial Power-up:

1. Upon the system’s first power-up, the initial password is set to a personal code of “1234” and an administrative code of “123456”.
2. In standby mode, the system displays the system date, time, and voltage status.
3. After a power outage, the password and records of door openings will still be saved, but the time might be lost. Therefore, you need to recalibrate the time after powering up again.

II. Door Opening Operation:

1. In standby mode, press the “#” key to start up the system. When the LCD screen displays “——-“, you can enter a 1 to 8 digit personal password and then press the “#” key to confirm it. (The system will automatically confirm after entering an 8-digit password)

2. If the password is correct, “OPEN” will be displayed, the electromagnet will be toggled for 5 seconds, and you can open the door during this time. The internal light will be on for 25 seconds.

3. If the password is incorrect, then “ERROR” will be displayed, followed by displaying “——” again so you can re-enter the password.

4. If you enter the incorrect password three times in a row, the screen will display an alarm symbol, and the alarm will sound for one minute. Entering the correct password at this time will disable the alarm and unlock the door.

5.  Clear function: During the password input process, pressing the “*” key once will clear the last entered digit.

6. Stealth function: Press the “*” key before entering password to switch to stealth function (single press enables stealth; double press disables stealth).
   When stealth is enabled, subsequent number entries will not be displayed and will be replaced with “o”.

7. If no key is pressed within 8 seconds during input, the system will return to standby mode.

8. Every instance of a successful door opening will be recorded and saved.

III. Changing Personal Password:

1. Change in “OPEN” mode: First open the door with your personal password. When the screen displays “OPEN”, press the “*” key and the system should display “——” which means it knows you want to change your personal password.

3. Then the screen will display the new password for 1 second before returning to standby mode.
4. Clear function: During the new password input process, pressing the “*” key once will delete the last entered digit.
5. If no key is pressed within 8 seconds during the password changing process, the system will return to standby mode (and old password will remain)

4. If no key is pressed within 8 seconds during modification, the modification status will exit (the password will remain the old password) and return to standby mode.

V. Query door access records:

1. To open the door, enter the password firstly. When the electromagnetic lock engages for 5 seconds and the screen displays ‘OPEN,’ press either the ‘0’ or ‘8’ key to query the previous door access records. Each record is displayed across two screens.

2. Enter the desired date and time by directly pressing the numeric keys in the format ‘year-month-day hour:minute’ (total of 11 digits). The corresponding setting digits will blink. After entering the values, the system will automatically confirm, save the new date and time, exit the setting mode, and return to the standby mode.

3. During the setting process, press the ‘*’ key to go back one digit and re-enter the value.

4.  The system will validate the input numbers for their validity. Invalid values that fall outside the specified range will not be confirmed. The valid ranges for each parameter are as follows:

5. Note: When modifying the date, the system cannot automatically differentiate between months with different numbers of days or account for leap years. Users must ensure that the entered date is meaningful and avoid artificial errors such as ‘February 30th’.

6. If the modification is not completed and no key is pressed within 8 seconds, the system will exit the modification mode (any changes made will be discarded) and return to the standby mode.

7. The system includes a perpetual calendar from the year 2000 to 2099. It automatically handles the transition between months with different numbers of days and accounts for leap years during timekeeping.

3.  After powering on, if the rear screen displays ‘GOOD’ (you can release the red button at this point), it means that the personal password and administrative code have been restored to their initial values of ‘1234’ and ‘123456’, respectively. Additionally, all door access records have been cleared.
