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.

DeviceBacklight

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.
