• Please note that instructions and explanation on security functions on the above table is
not included in the supplied “User’s Manual” or within the “Wired and Wireless Network
Setup Guide”.
• When you set WPA-EAP or WPA-EAP, be sure to set [DATE, TIME PRESET] before
installing digital certicates. (→ page 8)
If setting of [DATE, TIME PRESET] is not correct, a message “authentication error” will be
displayed.
• To install digital certicates on the projector, use a USB memory device in the market.

Other Notes
• Contact your network administrator for information about access point and settings
for authentication server (authentication method, encryption type, EAP type, and
digital certicates).
• For using the on-screen menu on the projector, see the “User’s Manual” (PDF) on
the supplied CD-ROM.
• See the supplied “Wired and Wireless Network Setup Guide” for instructions on set-
ting IP address, subnet mask, SSID, and WEP on the projector.
• WPA-PSK, WPA-EAP, WPA-PSK and WPA-EAP are available only when [INFRA-
STRUCTURE] is selected in [NETWORK TYPE] of the [CONNECTION] page. They
are not available when [AD HOC] is selected.
• WPA-PSK stands for “Wi-Fi Protected Access-Pre-Shared Key”, TKIP for “Temporal
Key Integrity Protocol”, AES for “Advanced Encryption Standard”, EAP for “Extensible
Authentication Protocol”, TLS for “Transport Layer Security”, PEAP for “Protected
Extensible Authentication Protocol”, MSCHAPv for “Microsoft Challenge Hand-
shake Authentication Protocol version ”, DER for “Distinguished Encoding Rules”,
