phone/microphone only one way. If you cannot easily
insert the prongs, turn the cord over and try again. Do
not force the connection.

Listening Safely

To protect your hearing, follow these guidelines when
you use an earphone.
• Set the volume to the lowest setting 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.
