Features:
● proUSB refers to Professional USB. With advanced driverlessness USB technology, without installing Driver File, It can be easily and conveniently used when there is Windows System in the PC with USB function.
● Easy lock configuration. Setup for Room No. and Clock isn’t needed to be operated. Only Read System Card (Authorized Card) three times over the Lock inductive area and use the corresponding Guest Card to open the door, Room No. and Clock is going to have accessed into Door Lock automatically.
● It is radical reform for proUSB System that having Lock Time kept pace with computer time theoretically in order to eliminate cumulative error (general speaking, the Time Difference between the lock and computer will be kept within 5 minutes).
