CONNECTING

To listen to your keyboard without dis-
turbing others, you can connect an op-
tional pair of stereo headphones with a

-inch (6.35-mm) plug. Your local Ra-
dioShack store sells a wide selection of
headphones.
Insert the headphones’ plug into the
PHONES/OUTPUT
jack on the back of
the keyboard.
Note
: Connecting headphones discon-
nects the keyboard’s built-in speakers.
Listening Safely
To protect your hearing, follow these
guidelines when you use headphones.
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 vol-
ume levels. Extended high-volume
listening can lead to permanent
hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a vol-
ume level that does not cause dis-
comfort might still damage your
hearing.
CONNECTING AN
EXTERNAL AMPLIFIER
To amplify your keyboard’s sound, you
can connect it to an optional external
amplifier using an audio cable with a
