Second step: Authentication and encryption
The next step depends on the authentication mode
selected in the previous step. Certain modes require
further parameters for encryption and authentication to
be defined.
Third step: Confirming setup and changing advanced
settings
On the last screen, confirm your settings. If needed, use
the
WLAN setup menu to view and edit, for example, the
IP address of your phone and the DNS addresses.
Select Advanced in the same menu to enable power
saving and change the RTS threshold value. Power
saving is recommended to be on, but in certain
situations, the available wireless LAN access point
requires it to be off to ensure a reliable throughput.
Tip These advanced settings are available during the
entire setup process, not just from this screen.

Device
Backlight
You can select how the display and keyboard backlight
should behave for handheld use and when the phone is
in a car holder. The lower the brightness you choose, the
longer the battery will last before it needs charging. Set
the car holder levels low enough so that you sustain
natural night vision.
Select
Tools > Control panel > Device > Backlight to
make the settings.
