You can connect the Digital Keyboard to a commercially
available stereo system or amplifier, or to a recording device.
You can also use the Digital Keyboard to sound output from a
portable audio player or another device, and use that as
backing for your keyboard play.
■ Sounding Digital Keyboard Output on an
External Device
Connection requires commercially available connecting cords,
supplied by you.
• The connecting cord should have a stereo mini plug on one
end and a plug that matches the configuration of the input
jack of the external device on the other end.
• Turn off the external device and the Digital Keyboard
before connecting them. Before turning power on or
off, turn down the volume level of the Digital Keyboard
and external devices.
• After connecting, turn on the Digital Keyboard first and
then the external device.
• If Digital Keyboard notes are distorted when they are
sounded on an external audio device, lower the Digital
Keyboard’s volume level.
