Convenient Functions
Disabling Buttons—Panel
Lock
By using the Panel Lock function, you can disable the buttons
with the exception of certain operations. This is a convenient
way to prevent buttons from being pressed inadvertently,
changing the settings.
When the panel is locked, the following operations can be
performed.
- Play using the piano sound
- Key Transpose
- Master Tuning (p. 23)
1. Before switching the power on, turn the
volume all the way down.

2. While holding down the [Piano 1] button,
press the [Power] switch.
fig.7-02.e
3. Adjust the volume.
Playing the keyboard now produces a Piano 1 sound.
It will not be possible to switch to another sound.
4. Switching the power off and back on again
releases the panel lock and returns the ep-
90/70 to its usual state.
MEMO
If you turn on the power while holding down the Metronome [On/
Off] button, it will also be possible to sound the metronome. You
will also be able to adjust the metronome tempo, time, volume, and
sound.
Transposing without
Changing Your Fingering
—Key Transpose
You can play in a different key—without changing the keys
you are playing.
When playing in a difficult key with many (sharps) or
(flats), you can transpose the keyboard to play in an easier
key.
Key transpositions remain in effect until the keyboard’s
power is turned off.
