Reset conguration
If you have forgotten the Admin PIN code, the only way to reset it to default is to do a 
hard factory reset. This is the same as the Factory reset in the system menu (MENU > 
SYSTEM > FACTORY RESET).
 This erases all settings including account information and contacts! 
  Disconnect the power supply cable. Note that this is the same as the network cable 
if the phone uses Power over Ethernet. 
  Press and hold the MENU button while you connect the cable again (i.e. starts the 
OmniTouch 4135 IP). Hold the button pressed until the SYSTEM RECOVERY menu 
is shown on the display.
 You can press any other button than 1, 2, or 3 to start the phone without resetting. 
 Press 1 to select Reset conguration and conrm with OK. 
  Upgrade to the latest version of the software when the phone has started and redo 
the setup of account and other settings (see page 9).
