Switch on produces a fast red blink.Remove and replace the same 2 batterys that are on the same side as "on" and get a green light.....WHY......?

Really don't know what that problem would be. Sounds defective - I've never had any issues such as you describe. Sorry.

The red light is supposed to blink constantly. If it isn't blinking, send it back.

Mine does this but the yellow light is blinking. Don't know why but unplugging it and plugging it back in fixes it... until the next time. :-/

I've never had that happen. I know on my drill battery chargers they will blink like that when the batteries are hot or too cold

According to the manual, you have to stare at the green light, which is on solidly, and watch for a red flash, and count the seconds between. About 30 or so seconds, the battery is okay. About half of that, and it is not. Keep reading- it doesn't work the way the manual says!!!! I have only caught one low battery this way. I have never had them chirp, due to a low battery- they have consistently set off all of the alarms in the house, full volume and noise, for several seconds- VERY disconcerting, especially to the kids, and to me, in so far as they automatically assume that it is a battery issue, versus leaving the house. To be honest, so do I, after having been awoken several times in the middle of the night, due to this incredible poor design, (or flawed construction- the instructions don't say that this is how they are supposed to work.) In one instance, I had checked for the red flashing light timing, for indication of a low battery, about 4 days before the stupid thing went off again. Maybe it is just me, but I have neither the time, nor patience, to stare at each of these things every day or two, for a minute apiece, in hoping to catch a low battery before they go off. If I had the option (I don't own the house,) I would gladly buy something else, and would have replaced them all, at my own expense, long ago.

Sounds like your gyro. It needs to be reset. Plug your battery in and immediately place QC on level surface...light will slow blink then fast blink. .. wait for the lights to stop fast blinking before syncing the controller (about 15 sec). If that doesn't work look for hair or carpet fiber wrapped around slow rotor

That is odd. Did you let it sit for a while? I remember blinking lights for sometime before the constant green light came on.I'd contact Amazon or the manufacturer to see if you can exchange it. Personally, I love mine and even gave one to my best friend for her birthday. I use DuraCell batteries.

Hold the center button for about three seconds. You will hear a tone and the red led will blink

My lights turn green on mine. I have 2 of them and they both work the same way.

I just plugged my charger in with two batteries. Light is solid red. Will turn to green when charged

On my unit the light is red, and it starts flashing red when I place a drained battery into it for charging. Once the battery is charged it turns green and stays green until I remove the battery to use it.

Maybe the battery is "old" without much power OR make sure you didn't put the battery in upside down. Check the numbers on the battery to make sure you bought the right one. When you press START, make sure the : is blinking

I'm not sure. Usually, the light is orange, then turns green once the battery is charged. The contacts are particular, but if they're lined up, and you're still having the same issue, I would think there was a problem with either the battery or the charger.

There is no on/off switch. Batteries installed should make the light blink. Yours must be defective...or your batteries are bad.

Mine has been charging for 6 hours and still red, not sure what to do...Only time I saw green light was when I first put the batteries on the charger while still unplugged. I thought this was odd.

The blinking light is when the battery is charging. The solid red is when the battery is fully charged.

I put on a full charge initially, and I believe that is what the instructions say to do. When you place one in the charger, the LED on the charging will be red until the battery is fully charged, then it will turn green. Make sure battery is placed on charger correctly, or a dead battery will generate a green light immediately, even though it is dead. If that happens, just unplug, replace the battery correctly on charger, and plug it in again. Works perfectly for me. My batteries were both red and needed charging when I received them, even though they had enough charge to power camera up right out of the package.
