Preparation

Listening Safely

To protect your hearing, follow these guide-
lines 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 volume
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 volume level
that does not cause discomfort 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
plug (not supplied).
To connect an external amplifier to your key-
board, insert the cable's plug into the
jack on the back of the keyboard, and con-
nect the cable's other end to the amplifier's
input jack(s) (such as AUX IN or TAPE IN).
Your local RadioShack store sells a full line
of amplifiers, speakers, and connection ca-
bles.
