Phone Reboot  
Periodically, the phone may need to be rebooted. Reasons for this include accepting a new 
configuration, new software upgrade, or restoring Busy Lamp Field appearances after Impulse 
maintenance.  
There are two ways to reboot the phone:  
  Unplug the power supply  
  Wait two seconds   
  Plug in the power supply  
OR  
  Press and hold the following numbers: 1, 3 and 8 until the phone beeps and shows 
Restarting Phone. 
 
Note: The reboot process is complete when the idle display and current time are on the screen.
