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
1. Before switching the power on, turn the 
volume all the way down.

2. Press the [Power] switch to turn off the 
power.
3. While holding down the [GRAND PIANO] 
button, press the [Power] switch to turn on 
the power.

4. Adjust the volume.
Playing the keyboard now produces a GRAND PIANO 
sound.
It will not be possible to switch to another sound.
Switching the power off and back on again releases the 
panel lock and returns the pt-2700 to its usual state.
You can set Panel Lock in Step 3 above by turning on the 
power while holding down any TONE button other than the 
[GRAND PIANO] button. In that case, you can play using 
only the tone of the button that was pressed.
