Double-card unlocking mode:
Take the customer card to contact the EM reader. One short sound with blue light flashing indicates
the card is read successfully. Then take a service card to contact the EM reader. Simple music on
indicates the card is read successfully. At this moment, the motor will rotate and door will be opened
(with lock bolt back into the lock core).
*Note: In the double-card-unlocking mode, the first card added by the Master card is guest card, and
all of the following cards are service cards. When unlocking the door, only when the customer card
and a service card together can the lock be unlocked. Which card to be read first is not required. Use
two service cards or two guest cards can not unlock the lock.
Clearing all of the unlocking cards: Take the Master card to contact constantly the EM reader. If the
card is read successfully, 5 rapid sounds of “beep” and following 3 long sounds of “beep” indicate that
all the guest card and service cards are cleared.
Switch to single-card-unlocking mode from double-card-unlocking mode:
please press the initialize button on the circuit board for about 3 seconds (or use something acerose,
lie toothpick, to jab into the small hole on the lock core).
Loosen the button when you hear a sound of “beep”. At the moment that you hear a long sound of
“beep” with 5 short sounds of “beep” following, the lock is initialized (all cards of the lock are cleared)
and in the single-card-unlocking mode.
