1.  Press the [Transfer] button. 
 
 
 
 
2.  Press [1][1][0].  
 
 
 
 
3.  To enable the hot keypad, press [0][3][1]; to disable 
press [0][3][0].

button. 
 
 
 
 
 
While using a hot keypad, the [Speaker] button LED lights when you dial a number 
and the speakerphone is enabled. Lift the handset when the call is answered if you 
want a private conversation.
