Sennheiser RS 220

  • Sennheiser RS 220 when trying to power on headset LED goes to blue then to red within 1 second.  Documentation does not address a red led.  After red led goes out and power button is not responding unless I open battery cover and reclose.  Then power button cycles blue/red/blank again.  Unit is new out of box.  Thanks for any help.

  • The red LED indicates the batteries are dead or there's no power. They do not come charged and must be charged for 16 hours prior to use.
