The  device  automatically  allocates  an  ID  starting from 1 for every user in sequence. If you use the ID allocated by the device, you may skip this section.
1.  Press  [User ID]  on the  [Add  User]  interface  to display the user ID management interface.

 Tip:  The  user  ID  can  be  modified  during  initial enrollment, but once enrolled, it cannot be modified. 

2. On the displayed keyboard interface, enter a user ID and press [OK]. If the message “The user ID already exists!” is displayed, enter another ID.

Tip: The device supports 1 to 9 digits user IDs by default. If you need to extend the length of current user ID numbers, please consult our commercial  representatives  or  technical pre­sales. 

3. After the user ID is entered, press [Save] to save the current information  and  return to  the previous interface.  Press  [Exit]  to  return  to  the  previous interface without saving the current information.
