How do you get this to work? Even with replacing with a new, new battery, it doesn't work at all. Piece of you-know-what.

check to make sure battery is in correct position: I have no problem with mine.

Mine worked perfectly right out of the box. If yours doesn't, just return it for your warranty.

You need to press and hold for a few seconds the 1st buton on the left side to turn it on (same thing to turn it off). If it doesn't work then it might be dead. You should be able to get a quick refund

As long as you are using a good battery,installed correctly, (its a little tricky,tight fit)hold the set button in for about 5 seconds.it will turn on.hold the set button to turn off too.

I've had the unit for several months, and it's worked flawlessly for me from the start. Just make sure you have fresh batteries in it for accurate readings. I'm very happy with mine; if you're having issues, ask for a replacement if you need to use this instrument for it's intended purpose.

Buying a battery might be a cheap fix. Make sure the charging unit is plugged in and it lights up when the unit is placed in the charger. If the unit is new, send it back.

I had the same problem and had to return the battery. I went and purchased a whole new unit. Careful if you order a battery because if you have to return it, Amazon doesn't let you because it is a hazardous item. I went through a lot trying to return it to the vendor. The one I received was also broken. Good luck.

Are you inserting the batteries correctly? If not contact Amazon to arrange to send it back for replacement. Mine works fine.

Change the batteries and try it. Return unit if it still doesn't work properly.

maybe, your software/firmware might need refresh and or update, if still not working after that then yup it's probably dead...(might try new fresh batteries too....)

I am sorry, I had the same problem. I ended up throwing it away and ordering a new one! I did not see any way to open it and replace a battery.

Try removing the battery and reinstall it...mine stopped working after few days and that worked for me.

Buying a new battery won't help. The charging jack on mine was bad. Sell it to Amazon and then you pay the difference to get a refurbished one. The replacement one is guaranteed. Hope this helps you.

I guess I would change the battery, I had to change mind before it would work right out of the box. Good luck!

I had the same issue with the replacement battery. It stopped working after about 3 months. I complained to amazon and got my money back.

Mine works perfectly. I would send the defective one back if you really cannot get it after following the instructions, and ask for a replacement; I'm sure they'd send you one...

I'm sorry to hear that. Mine seems to be working fine. I've used mine for more than 6 minutes. Make sure it is fully charged before using it.

I had same problem...it's either an internal battery or charger issue and it's not fixable...just return it. The new one I got (same model) works though.

I agree. Send it back. Mine has been perfect. Changed the battery once and it works great.
