Door Electronic Locks

When all keys are unlighted, pressing the asterisk (*) at the lower right sounds a doorbell.
Unit may be unlocked using password (for Admin), fingerprint (residents; press finger well on the scanner), card (for example, lent to guests) or remote control.
After 5 invalid entry attempts, the lock sounds an alarm. Unit also displays “Warning” and a countdown for 180 seconds. Use remote control to open immediately, or just wait and try again. (The Admin cannot override it with a fingerprint, password or card.)
To keep always unlocked: Admin unlocks, then press “2” & “8” (which by the way always light up whenever the Admin unlocks). Unit displays a check mark and “Unlock setting”, while voice says “Already entered open normal mode”.
To return to normal lock mode (instead of always unlocked): Turn knob to make latch appear one second, then turn knob back so latch disappears. Unit displays “Lock setting”, while voice says “Normal open mode already cancelled”.
To enter the Admin Menu: Touch the scanner with a wrong fingerprint to light the numbers up, and wait for “Input keys” display. Press “0” & “#”.
