1.2 Adusting Your Telephone’s Pedestal  
(Model 8201N only)  
An adjustable pedestal is provided on your telephone to allow you to  
select the most comfortable viewing angle. When you receive your  
telephone, it will be in its lowest position — down flush against the  
pedestal. You can raise your telephone to one of three higher positions  
as follows:  
1. Grasp the rear of the pedestal base firmly with one hand while  
lifting the rear portion of the telephone upward with your other  
hand.  
2. While pivoting the telephone upward with one hand, pivot the  
telephone supporting arms upward with your other hand while  
feeling for the notches under the telephone. Notice that there  
are three sets of notches under the telephone corresponding to  
the three positions available.  
3. When the telephone is at your desired height, find the closest  
pair of notches corresponding to that height, and engage the  
supporting arms with the notches. Press down slightly on the  
telephone until you feel the supporting arms snap into place.

codes. You do this by pressing the INTERCOM button after you hear  
the outside line dial tone.
