If WPA encryption is set for wireless LAN communication and the encryption method is set to WPA2-PSK, use this page to set or change the Pre-Shared Key (PSK). The system uses PSK to generate the encryption key.

### New PSK

Enter the PSK you want to set or change, using 8 to 63 alphanumeric characters. Spaces can also be used.

### Confirm PSK

Enter the same PSK again in the confirmation box.
The PSK entered here must be the same as that entered earlier in the New PSK box, otherwise it cannot be set.
