    • Check if cable is damaged or loose
    • Use different network port if available

    • Ensure IP is in same network as server
  3. Restart Device:
    • Press and hold Mode + Enter for 10 seconds
    • Device will reboot
    • Wait 2 minutes for full initialization
  4. Check Firewall:
    • Allow port 5005 in Windows Firewall
    • Disable third-party antivirus temporarily
    • Check router firewall settings

Attendance Not Syncing

Data sync failures are another frequent issue.

Troubleshooting Steps:

  1. Manual Sync:
    • Open Paytazz or eTimeTrackLite software
    • Click "Sync with Device"
    • Wait for process to complete
  2. Check Device Memory:
    • Device memory full = sync fails
    • Delete old records from device
    • Keep only last 6 months of data
  3. Verify Device Time:
    • Device clock must match server
    • Set via software or device menu
    • Enable NTP for auto time sync
  4. Check Software Settings:
    • Verify device IP in software
    • Check port number (default: 5005)
    • Ensure user has permission to sync

LAN Connection Issues

Problem: Device connected but data not transferring

Solutions:

  • Check Cable Quality: Use Cat5e or Cat6 cable, not damaged
  • Network Speed: Ensure minimum 10 Mbps connection
  • Check Switch/Router: Verify port is not blocked

  • Reset Network Settings: Restart router and device
