3.8.3.2. 1:N Level Setting 
<1:N Level> 
3 4 5 6 7 8 9 
[ESC][ ]← [ ][ENT]→  
  Default setting: ‘4’ 
This is the menu that sets the authentication level in case of using only 
fingerprint input without ID input. 
This function is used to locate the corresponding fingerprint by comparing the 
fingerprint entered in the fingerprint input window with the fingerprints saved in 
the terminal database. 
    In case of 1:N authentication level, setting authentication level for each user is 
not allowed and terminal's authentication level is used as basis. 
Press [ENT] button to continue setting. 
3.8.3.3. LFD Setting 
<LFD >

[ESC][ ][ ][ENT]↑↓  
  Default setting: ‘0.None’ 
This menu sets the LFD level that can prevent the input of imitation fingerprints. 
A higher LFD level strengthens the function for preventing the input of imitation 
fingerprints made using materials such as rubber, paper, film and silicone. 
However, a higher LFD level may also prevent the input of real fingerprints if 
they are too dry. 
After selecting a setting value, press [ENT] button to continue setting.
