You can connect the keyboard to a PC for data exchange via the USB interface.
NOTICE!
To prevent damage to the speakers, turn the volume down to ‘Mini‐
mum’ before you connect other devices to the keyboard.
Use the connection socket
[SUSTAIN]
to connect a sustain pedal to the keyboard.
On the rear panel of the keyboard, you can connect headphones to the
[PHONES]
output socket.
Connecting headphones (not supplied) to the output mutes the speakers.
Never operate the headphones at high volume as this can permanently damage your
hearing.
Use the
[AUX IN]
connection socket to connect a, for example, CD or MP3 player to
the keyboard. So you can playback music through the internal speakers of the key‐
board and simultaneously play along to it. Connect the cable to the
[AUX IN]
connec‐
tion socket on the rear panel of the keyboard, and the other end of the cable to the
output of the respective audio device.
