Keeps turning off after just a few seconds?

There are 4 buttons that should be preset to different time amounts. Or you can also set them. I think mine came with A (10sec for base cure) and the. B, C, D are 90, 120, 180. If thats not it. Check that you have bulbs plugged in firmly. They might be arc'ing? Hope that helps.

Turn to off and then turn it back on. Sometimes you my have to unplug it for a couple of minutes.

Hold the top right hand button down for like 5 seconds. It will make a, what I call a "power down" noise.

Hmmm, Only suggestion I can make is to unplug the power to it and plug it in again, sometimes it needs to be restarted.

You can push the on and off button and hold it in for about 4 or 5 seconds. It will shut off after a 4 or 5 count. Also turning it on some times hold in for 4 or 5 seconds and it will turn on all the way. Hope this helps you, I found this out by accident.

It switches itself off after a minute or two. Consumer-type calculators haven't had an on/off switch for 30 years.

It turns itself off relatively quickly once no activity happens for a few minutes. I have never timed it to see how many minutes....maybe 4 or 5?

Let me understand your question. You want to turn the device off? Just hold down for 3-5 sec the power button.

The light will automatically turn off by itself if you just wait a few seconds

It turns off and stays off until you turn it back on again. There's a 30 minute option as well.

I've only used it about 2-3 times but didn't have trouble with it turning off and on. Maybe there's a malfunction??

I just timed mine and it takes a full minute before it times out. I've never felt that the time to power down was too short.

No Auto shut off, and no timer I'm afraid...I just turn on for few minutes here and there.

It auto shuts off in about 4.5 min from last use. Odd number but I verified it 3 times.

It's weird! Turn it off, then there is a little thing that sticks out on the back - press that, then turn it back on and it should switch.

Sounds like its bugged. Click to turn on, use, and it times out and turns off automatically.

Yes, I am having this problem currently. I press power (on the remote) to turn it off, it turns off briefly then on again after 5 seconds. I have to turn it off 5-6 times before it sticks.
