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.

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.

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.

No, your casio needs a 9 vt. if you look at the power connector on your casio, it should specify the power andpolaritty required.

Make sure it is compatible. Match the voltage and amperage on the keyboard with the power cord's specs. If you don't, you may damage the keyboard.

Suggest you power with batteries and try the keyboard. If no problem it is likely the power adapter has a problem, or loose connection. I've included the manual to help you discover the problem and resolve,

Hope this helps? http://support.casio.com/storage/en/manual/pdf/EN/008/CTK451_EN.pdf
