CHARGED THE BATTERY AS INSTRUCTED, UNIT DOES NOT WORK

Read the instructions and if you are certain the headphones aren't operating out of the box as per the instructions, return them under warranty.

Mike, The red LED is suppose to be on when you insert battery, the LED will go green when battery is charged. Look in your manual, Pg. 11 charging instructions. Check the attached links,manual,instruction and guides, Good luck

How to Check Li ion Battery

Red light normally means that the battery needs charging. The green flashing light can mean the battery is charging or has charged, and the same with the solid green light. Green in this case is good.

Charge the unit overnight and see what the indicator state is. It should not take more than 8 hours of charging for a Li-ion battery. Once you know what the full state light looks at, then you can tell what the charging indicator looks like.

In all cases, ensure you are using the proper charger with the unit.

This unit is recharged using any household 120v outlet. Remove the rubber cap from the recharge port on the top of the unit. Plug the barrel end of the adapter cord into this port and then the put the adapter into the wall outlet. Make sure the power switch is in the off position. To check the charge level push the button to the left of the 3 indicator lights. When the green LED lights up, the unit is fully charged, (yellow is moderate charge and red is minimum charge).
Try to charge the unit from the minimum (red) charge level to maintain the maximum battery life and use of the product.
If you have misplaced the manual I am providing a link to it from Black and Decker's site.

I have the same problem. When I try to charge a battery the green LED onthe charger flashes green and the battery does not charge. Any ideas?

remove stater and service, unit may be poling off and drawing down battery check ignition relay unit may also be faulty.

check the dial tone is not set to pulse also delete any messages from bt 1571 and the light will stop flashing

My experience was similar to yours. The LED turned green after about only 2 hours. Because I didn't want to stay up until midnight to start playing with my Axim, I took it out of the cradle after the 2 hours and everything was fine. Besides, having downloaded and read the user's guide 2 days before receving my Axim, I knew that a green LED meant it was ready to go. 3 days later, everything is still fine and seems normal. A year ago, I received a Palm with similar initial charging requirements, and it also didn't take as long as the directions said it would.

It may be your main battery is dead. I had the same problems and had to replace the main battery and everything worked fine!
