If your Bluetooth® headset will not accept a charge, the battery may need to be replaced or there may be a loose connection. Try the following steps to troubleshoot this issue:
- Make sure to use the supplied USB cable. The headset may not charge if another USB cable is used.
- Verify that the USB cable is firmly connected to both the headset jack and the USB port on the computer.
- Make sure that the USB cable is connected directly to the USB port on the computer and not through a USB hub. Charging will not be completed with an indirect connection.
- If possible, try plugging the USB cable into a different USB port in the computer.
- Make sure that the power for the computer is turned on.
- Verify that the computer is not in standby or hibernation mode. Charging will not be completed if the computer is set to these modes.
- If the headset is not used for a long time, the headset indicator may not light up when you connect the USB cable. Do not disconnect the USB cable. Wait a few minutes to see if the red indicator will light up.
- If the battery is not used for a long time, the battery may be completed depleted. The battery should improve after receiving a couple of full charges.
- The battery may need to be replaced if the life of the battery drops to half the normal length.
- Make sure that the area where the unit is being charged is within the ambient temperature range of 32-degrees to 104-degrees Fahrenheit. Always avoid exposure to temperature extremes.
