How do you silence this thing?

take off the screws on the calculator and find the wires where the speaker is at and cut them with a pair of scissors and BAM NO MORE SOUND!

You can turn the volume low enough that you cannot hear it. Check your settings.

Yes it very simple. Turn up the radio and start whistling yourself. It will go away!

Yes. There is an opening on the side to turn it on/off silent. It is small though, and having nails helps!

No there is no way to turn it off. Unless you tried to pull out the speaker. Which I'm sure would void any warranty, I'm not sure how hard that would be either.

I have asked, and did not get an answer from the company. If you find out a way to shut it off, PLEASE let me know.

What you are hearing is the PlasmaWave. Hold down the power button for 3-5 seconds and it will turn off the PlasmaWave feature (and the sound goes away).

It is not silent. Mine has a tube that takes the water out of the window so no need to empty.

If it sounds, anyone can turn it off. Not sure what purpose it would serve when you are not present. The battery probably would not last several hours.

There is a button switch that you can use to put the unit in the " silent" mode....not audible to humans.Works great in either mode. I only use audible mode to periodically verify batteries. Good Luck.

Actually, no. It's quiet silent. I was surprised to hear it. I thought it would be way more noisy.

You have to power it down. There is no mute function. I take mine off to shut it off because you have to hold the power button for between like 6 and 10 seconds. The power button is directly across from the earbud so it shoves it into your ear. So in short, no...

No I am unable to turn the sound off as it is a ticking timer. It's the mechanism itself that makes the noise.

The only way you can shut it off is by pausing a song and then press the hold button. It will go off and say see you later. Goodluck!!

You can't shut it off. The closer you get to the unit the more it barks. Otherwise get a real Dog.

It is not silent, but not noisey either. a good pad underneath would limit the noise.

I'd suggest wearing earplugs. It's loud and close to your ear when you're holding it. It does blow in your face, too, but it's very effective and powerful.
