Casio Privia Px330 Px-330 88 Key Digital Piano New - Page 5 - Answered Questions & Fixed issues
MY Casio CTK-591 is making a loud 'hummin Noise when I turn it on. Ideas on how to fix?
I assume you mean through its own speakers.
(If you are running through an amp, make sure everything is powered from the same power point)
If the hum is coming from the unit but not through the speakers, you have a more serious problem.
If you are not using the supplied power adapter that could be the problem.
If you are using the mic input, the mic lead could be the problem, or it might be passing close to the power adapter or some other hum source. try a different lead, and make sure the lead is well away from everything.
Some other device might be too close. Try moving things around, or a new location.

How do I factory reset Casio lk 110 keyboard?
Unplug while unit is on. Then press and hold power button for about a minute. Replug back in see if that does trick. If not call company for a hidden code if available.

Casio 3426, tone sounds every 20 min.

At the top of page 3 is instructions to change the time. Notice in the diagram there is a step in which you have the choice to turn off the tone. Try that.
Secondly, try entering alarm mode, as described at the top of page 2. I suspect you have some alarm set. Remove it if you find it there. Note that you only have a couple of minutes in which to make the alteration before the watch automatically kicks you out of the alarm mode.
