⚠️ Cautions​

warning
  • Fingerprint deletion cannot be undone — must re-register if needed
  • Deleting fingerprints does NOT delete the main PIN — other settings remain
  • If no fingerprint to delete, press R to exit
  • If an error occurs, LED [0] lights
  • 5 consecutive failed scans = Anti-Prank + 1-minute lockout
  • Must register a valid fingerprint before deletion
  • All fingerprints will be deleted if using LED [3] in All at once mode
