The device is equipped with a rechargeable storage battery for power outages. Ensure the backup battery switch (located inside the settings panel) is in the "ON" position to enable this feature. This also supports data memory backup.
Operating Instructions
1. Inserting a Time Card
Gently insert an employee time card into the designated slot at the top of the time clock. The device will automatically detect the card and position it correctly for printing.

2. Punching In/Out
Once the time card is inserted, press the appropriate "IN" or "OUT" button on the control panel. The time clock will print the current time onto the card. The device automatically handles in and out settings and verifies the card's correctness.
3. Two-Color Printing
The time clock uses two ink colors to indicate attendance status:
- Black Ink: Indicates regular attendance.
- Red Ink: Indicates abnormal attendance (e.g., late arrival, early departure), providing a clear visual alert.
4. Tracking Employee Attendance
The time clock is designed to accurately track employee start times, pause times, lunch breaks, and end times. Deductions for lunches and breaks can be managed directly on the time cards.
Maintenance
1. Cleaning
Regularly wipe the exterior of the time clock with a soft, dry cloth. Avoid using abrasive cleaners or solvents. Ensure the time card slot is free from dust and debris to prevent jamming.
2. Ink Ribbon Replacement
When the print quality deteriorates, the ink ribbon may need replacement. Refer to the internal settings panel access (using the key) for instructions on how to safely replace the ink ribbon cartridge.
3. Backup Battery Check
Periodically check the functionality of the backup battery. Ensure it is charged and the switch is in the "ON" position to maintain operation during power interruptions and protect data integrity.
Troubleshooting
- Device Not Powering On:
- Ensure the power adapter is securely connected to both the device and a working electrical outlet.
- Check if the backup battery switch is in the "ON" position.
- Time Card Not Printing:
- Verify that the time card is inserted correctly and fully into the slot.
- Check if the ink ribbon needs replacement.
- Incorrect Time/Date Display:
- Access the internal settings panel using the key and adjust the time and date settings as per the setup instructions.
- Red Ink Printing Unexpectedly:
- The red ink indicates abnormal attendance. Review the time settings and employee punch times to ensure they align with expected schedules.
