Question about Music
I have an E-20 the will not tune to 440. I try but it will go from Ab to Bb but wont stop on A. Any suggestions ????
Keyboard has internal battery. change it and it will retain memory of all settings + tuning. should'nt be too hard to dissasemble and get inside.

While the setting is shown in the display, press the CALIB key to
set the calibration.
Each time you press the key you will cycle through the following
0: 440 Hz 2: 442 Hz 4: 444 Hz 8: 438 Hz
1: 441 Hz 3: 443 Hz 5: 445 Hz 9: 439 Hz
When you have made the desired setting, wait approximately two
seconds without pressing the key.
The indication in the note display will blink three times, and the
calibration setting will be completed. You will then return to tuning
Just do it and stop on the 440 one.
