Note: Connecting headphones discon-

To protect your hearing, follow these
guidelines when you use headphones.

• Set the volume to the lowest set-

ting before you begin listening.
After you begin listening, adjust
the volume to a comfortable level.

• Do not listen at extremely high

volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.

• Once you set the volume, do not

increase it. Over time, your ears
adapt to the volume level, so a
volume level that does not cause
discomfort might still damage your
hearing.
