Avoiding Discomfort
To avoid strain or discomfort to your body:
• Place the phone where it is most convenient for you to reach it, without straining any part of your body.
• Do not cradle the handset between your ear and shoulder; use the headset instead.
• Do not expose yourself continuously to loud sounds; keep the volume of the handset receiver and headset
at a moderate level.
