Theatre Earphones and Volume Control

Damage to Hearing: The Theatre can operate at volumes loud enough to cause damage to your
hearing. To avoid this and protect your hearing, follow these guidelines:
Keep the volume low. Set the volume at a level where you can hear noises around you
clearly. You should be able to hear someone nearby speaking in a normal tone of voice.
If you cannot hear people around you speaking, even with noise-canceling headphones,
the volume is too loud. You could damage your hearing.
Do not increase the volume while listening. After listening to the Theatre for some time,
you will become accustomed to the volume and may want to turn it louder. However,
this can still cause damage to your hearing. Do not change the volume while using the
Theatre.
