3.3.1.5. “5. ID&PW|RF&PW” registration 
 RF-Card and password registration, ID input and password authentication or 
card and password authentication 
 [ENT] ◆ Æ [1] Æ [1] Æ User ID [ENT] Æ [9][3] Æ Place the card   
Æ Input password + [ENT] Æ Input same password + [ENT] ◆ 
In this case, a card is used instead of ID for authentication. This is helpful to 
users who have difficulty inputting their ID. 
After Card registration (refer to “1. RF” registration), password registration 
(refer to “2. ID&PW” registration) follows. 
3.3.2. Delete User 
 [ENT] ◆ Æ [1] Æ [2] Æ User ID + [ENT] ◆ 
In the main menu, press [1] to select “1.User” and the following screen appears: 
1. Add 
2. Delete 
3. Modify  
4. Add Admin 
5. Delete All
  To select delete user, press [2]. 
After entering the user ID to delete, press [ENT] you will hear three short beeps 
and all the information about the user is deleted. However, the information is still 
stored in the server. To completely delete this information, the data in the server 
shall also have to be deleted.   
If a non-registered user ID is entered, “2.Delete” appears together with an error 
tone. 
Caution is required when deleting a user or an administrator. The user just 
registered in the unit (not in the server) is not recoverable, so special care is 
required.
