Prolonged use of the handset can lead to neck, shoulder, or back discomfort, especially if you 
cradle the handset between your ear and shoulder. If you use your phone a lot, you may find 
it more comfortable to use a headset. See the section on headset usage elsewhere in this guide 
for more information.  

Your phone has a control for adjusting the volume of the handset receiver or headset. 
Because continuous exposure to loud sounds can contribute to hearing loss, keep the volume 
at a moderate level. 

The stand built into your phone tilts to give you a better view of the keys.  

To tilt your telephone for better viewing:  

1.  Turn the phone so that the front faces away from you. 

2.  Hold the base unit firmly and press the release tabs on the sides of the stand to detach 

the base unit. 

3.  Hinge the hooks of the base unit into the notches on the back of the phone and snap 

into place as follows: 

•  For a high–angle mount, hinge the two lower hooks into the bottom set of notches 

and snap the two upper hooks into the middle set of notches. 

•  For a low–angle mount, hinge the two lower hooks into the middle set of notches 

and snap the two upper hooks into the top set of notches.
