4.3.3 Wireless installation 3/3
If you have WPA security on your router, enter the
passphrase with the characters on the remote control. If
you have WEP security, the TV asks for the WEP encryption
key in hexadecimal numbers. Find this hexadecimal key in
the router software on your PC. Write down the first key of
the WEP keys list and enter it on TV with the remote control
keypad.
If the security key is accepted, the TV is connected with
the wireless router.
Next time you start the wireless network, there is no need
to enter the security key. The TV uses the security key you
entered in the installation.
