You NEED to keep it on the lowest setting and SLOWLY increase the setting. It is a powerful little device, and you need to use it like you would a medical device, because that is what it is. This goes double if you are a new user, your body will not be used to it unless you attune yourself to it. The manual reiterates this several times; don't ignore it. If you use it right, it's a wonderful little device that works miracles. If you use it incorrectly and don't pay attention to the manual (I.e., putting it directly on your spine? THAT'S A NO), then you will be in for an incredibly uncomfortable experience. We love ours and use it regularly :)

I use it all the time, works great for me. Make sure all the connections are secured. ie: the pads, if pads are loose, you will get a jolt. Found out the hard way. Try that.

I had similar issues myself. I just messed with the cord a whole and it started back working. This was a waste of my money.

I'm sorry, but I'm completely "power stupid"! I plug it in...it runs, I cut, I open the next beer. I tend to imagine the higher voltage would want to fry the motor, but again...what the heck do I know?

How can I do? I did not know how to control it and broke it. I believe that it is my problem. Thank you very much

Mos tlikely a 'fail safe' from power surge to protect your unit. Mine did the same thing for days as I scratched my head and tried numerous things. Discovered it was a shorted out and crossed iwred speaker wire from one of my Polk Audio sourround speakers. It was shorting and causing the unit to shut down. I had to connect a different amp to find out. My Sony told me it was a bad wire connection.Check ALL your cables, wires, and connectors. All must be tight and not shorts. All tips must be terminated properly.

Not a bad unit Jay. It picks up interference from the internal electronics and power cord. Did you put the ferrite choke on the power cord? I am not too impressed with this unit. For 1000w witch I doubt and the money I would not buy it again. Ken

This is one of those duh questions, but we've all done it. Did you flip the power switch on? If so and it's not working, you may have gotten a defective unit.

i wish i could help...my unit stopped working 3 weeks after purchase and has not worked for the past ~month. i will most likely throw it in the trash can. the manufacturer said they would send me a power adapter. i never recieved it. i am thinking twice about ordering anything from amazon as they appear to not care at all for their customers. it maybe time to revisit the brick and mortor stores. sorry for the venting. i wish could have helped

The same thing happened to me. I think the computer shorted out. I ended up returning the item. Make sure you put the batteries in correctly and then turn it on and off two or three times. That worked for me but it crapped out about three days later.

Don't make the same mistake that I did -- return this product ASAP. I kept trying to get mine to work properly until it finally would not work at all. My E-Prance is now in the landfill. I purchased a Cobra unit from Amazon that works well.

Mine did it not even work from the beggining......maybe I got a defective unit. Good Luck

Sorry to hear that Scott. I would open it to look for obvious damage Luke a fuse or loose wire orr burned power supply.

I have had this same thing happen to me after only ONE WEEK! Same answer.....tighten spring, re-install. This issue gives you an impression that these units are not made well!

This hasn't happened to me, maybe your power or negative source came loose. Check those connections .

Wow.. Can't say that happened to me. I hooked it directly to the battery. Sounds like you might have a short circuit. Did the wire get pinched or stripped between the battery and the power supply? You might want to try disconnecting at the battery to test.

I am guessing you have a defective one. Mine works perfect; on/off and nothing more.

I'm having the exact problem with the unit I just bought from Amazon. I'm wondering if it's a bunch of faulty units :-/
