Household power outlet
• Always unplug the AC adaptor from the power outlet if
you do not plan to use the keyboard for a long time, such
as when leaving on a trip, etc.
• When not using the keyboard, turn off power and unplug
the AC adaptor from the power outlet.

Polyphony
This keyboard can play up to four notes at the same time when there is no pattern or Song Bank tune being played. Even if
you press more than four keys, only four notes will sound at the same time.
Digitally Sampled Tones
This keyboard features a number of digitally sampled tones, which are digital recordings of musical instruments. Actually,
three recordings are made for each tone, covering the low range, middle range, and high range.
• The point where the key to the left falls in one range and the key to the right falls in a different range is called a “split point.”
With some tones, you may notice a very slight difference in tone quality or volume between the two keys at a split point.
This is an unavoidable result of the sampling process, and does not indicate malfunction of the keyboard.
• The sounds of some tones do not change pitch no matter which keyboard key you press.
