The MD-3 stereo speakers offer high-quality audio when you listen to
music or the radio on your compatible Nokia phone or audio device. The
speakers have a 3.5-mm stereo audio plug (located at the base of the
speakers). With the supplied AD-15 or AD-50 adapter, the speakers can
be connected to a compatible Nokia phone that has a Pop-PortTM
connector or to a compatible device that has a 2.5-mm audio connector.
Read this user guide carefully before using the speakers. Also read the
user guide for your phone, which provides important safety and
maintenance information, or the user guide for the compatible audio
device.
