Restarting your phone 
From time to time, you may need to restart your phone, for example, so that it can accept a new 
configuration on Horizon. To restart it: 
-  Press Menu. 
-  Select Settings then Basic and Restart Phone. The message “Are you sure?” appears. 
-  If you want to restart your phone, press Yes. 
The re-start process is complete when the idle display appears.
