1.3 Functional overview
(1) Data verification function
・The card lock is unlocked only when the data (property code, room number, time, etc.)
set in advance by the DTU and the key data (property code, room number, shelf life,
etc.) read from the card and smartphone are verified and determined to be valid.
・When a valid card is holden on the card reader (target mark), the LED on the top of the
card reader lights up in green and unlocks.
If the key data is judged invalid, the LED lights in red and does not unlock.
・When you hold a valid smartphone over the card reader (target mark), the LED on the top
of the card reader flashes orange and then lights green to unlock.
If the key data is determined to be invalid, the LED flashes in orange and then lights in
red and does not unlock.
If the room number is different, the LED flashes in red and verification isn’t performed.
・If reissued and newly issued valid card and smartphones are used, the card and
smartphone that were previously available cannot be used. As a result, prevents
unauthorized use of missing card and smartphones
(2) Usage history function
・Record up to 600 unlock operations using the card and smartphone, and operation history
using the DTU from the new date and time.
When the number exceeds 600, the oldest data is overwritten.
・Up to 100 unlock operations with verification error are recorded in newest to oldest order.
When the history data exceeds 100, it is overwritten in oldest to newest order.

used 10 times a day).
・When master card/ sub-master card/ master lock-out card/ housekeeping lock-out card/
cancel card/ daylight saving card/ is used, you can detect low remaining battery level by
using LED and buzzer (low battery detect function).
