When charging the red light flashes for ten seconds and the just the green light flashes until it eventually turns off. this does not charge it at all.

The batteries won't charge. You might want to google around for replacement batteries.

First I'd try a factory reset. PRess the +, - and multifunction button for 6 seconds until the blue light flashes and it shuts off. When you turn them on next, it's in pairing mode and try again.

I need a charger for this

Ridgid charger lights read as follows: Solid red; charger has power. Flashing red; charger is evaluating the battery, checking if it's cool enough to charge and if it is in chargeable condition. If the battery is hot, i.e. just came off the tool after extended use, it won't charge the battery until it cools down. Flashing red & green; the battery is defective and the charger will not charge it. Solid red & flashing green; battery is charging. Solid green; battery is full.

Sounds like it's time for new batteries.

Try a system reset:
1. Lift the headset off of the charging cradle (the base).  Make sure the headset is turned off.  The green light on the base won't be on if the headset is turned off. 2. Hold down the call answer button on the headset at the same time as mute button.  The mute button is found on the little black wheel on the top of the headset.  Use the tip of your finger to push it straight in. 3. Hold both buttons until you see a green light on the headset flash.  It will be right below your thumb.  Hold both buttons until the green light flashes for a series of 2 flashes.  Then let go of both buttons. 4. Put the headset back on the charging cradle and wait 30 seconds.  Lift it back off and try again. 5. If this doesn't work repeat the process once more or try a resubscription.
Resubscription procedure:
1. Put the headset back onto the charging cradle.  Make sure the red light on the base is on and the yellow light is flashing. 2. On the back of the base there are two buttons for the microphone adjustment that can be pressed down.  Press both of those down until the red light and yellow light on the front of the base start flashing. 3. While the headset is still on the charging cradle press and hold the mute button until the red light on the base goes solid, and the yellow light stays flashing. 4. Unplug the power to the base and then plug it back in. 5. Wait 20 seconds and try.

The first time you install ink cartridges, the printer must charge its print head for about 90 seconds. Wait until charging finishes (the green power light stops flashing) before you turn off the printer, or

it may charge improperly and use excess ink the next time you turn it on. If the printer stops moving or making noise, but the green power light is still flashing after 5 minutes, turn off the printer. If the light is still flashing when you turn it back on, contact Epson.

Turn off the printer, then make sure the ink cartridges are inserted completely and the ink cartridge cover is closed completely. Also make sure no packing material remains in the printer. Wait a moment, then turn the printer back on to clear the error.

Have you activated phone yet? When phone is activated and in service it flashes green. It's hard to believe it would flash green without a SIM card, as there is no service...unless AT&T is providing emergency service only and you're getting a flashing green which means you're in range of their towers.

Hello,
Here's a copy from the owners manual:
■ Charging LED 
Red LED is on = Being charged 
Red LED is blinking = Charging error 
Green LED is on = Carging is complete


● If the charge indicator blinks as red, it indicates a battery charging error.
- The battery is not properly inserted
- The terminals of battery are dirty or damaged
If the battery is inserted properly and the charge indicator continues to blink, contact the
nearest Samsung Camera Service Center.


Another charging error is when the batteries are so depleted, they won't charge up to 100% anymore = red light doesn't go out and remains on for too long, means get a new battery.

OK ... after a lot of trial and error, I got mine to work. I think it may be a really low charge or something. I had to press the power button until it was completely dark ... no flashing faint green or any colors. Then when I plugged it in, I got a solid red and left it for awhile. Then when I pressed the power button I got yellow, red and green ... the computer recognized it and then got a solid yellow.

Before when I had it plugged in, I'd get a lot of red random flashing ... and it just didn't seem to charge at all ... even after a full day.

I think the issue was that it was in this "flashing state (red when connected, very faint green when disconnected)" It wasn't easy to get it to turn off completely. Most of the presses of the power button didn't change the state at all. But if I got it just right, I could see the faint green light go off. That's when I plugged it in and got a solid red light, and eventually a good charge.

Hope this works for some others.
