To
use the projector over a wireless network, install the optional
Epson 802.11b/g/n wireless LAN module (PowerLite
L400U/L500W/L510U/L610/L610W). Do not install any other type of
wireless LAN module.
Caution:
Never remove the module while its
indicator light is blue or flashing, or while you are projecting
wirelessly. You may damage the module or lose data.
