key indicator, headset key indicator and the on-screen icon/error messages, which are
useful for you to figure out the cause of your phone’s failure.
The following are two examples of getting the device information from status indicators:

If a LINK failure of the IP phone is detected, a prompting message ―Network
Unavailable‖ and the icon indicate the current network LINK status.

If the power LED is off, which indicates the IP phone is powered off.
For more information about the icons, refer to Reading Icons on page 14 .
Sometimes, configuration errors may lead to your phone’s failure. You can export
configuration files to view the current configuration of the IP phone and troubleshoot as
necessary.
To export configuration files via web user interface:
1. Click on Phone->Configuration.
