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 use for more information.

continuous exposure to loud sounds can contribute to hearing loss, keep the volume at a
moderate level.
