Maintaining Your Phone 
When your phone is unable to operate properly, you need to investigate or troubleshoot issues 
among other tasks your administrator may ask you to perform. This chapter explains how to 
perform maintenance tasks on your phone: 
  Diagnosing the Network 
  Rebooting Your Phone 
  Resetting to Factory Settings 
  Updating the Phone Configuration 
  Export All Diagnostic Files 
Diagnosing the Network 
The wrong network settings may result in inaccessibility of your phone and poor network 
performance. In this case, your system administrator may ask you to use the “Ping” or “Trace 
Route” method to check whether the network is connected, and to analyze the network fault. 
Checking the Network Using “Ping” Method 
Procedure: 
1.  Navigate to Menu->Features->Diagnostics->Network->Ping. 
2.  Enter the desired IP address or URL in the Ping IP or URL field. 
3.  Press Start. 
The screen displays the network status information. 
 
4.  Press Back to back to the preview screen.
