    Here's from the hardware reference manual:

    The front panel of the 6400/6600 contains only the Power button  and the radio’s backlights.  The Power button is used to turn the radio on and off and is illuminated with a number of colors to indicate the radio’s operational state: 

    • FLASHING GREEN: Radio is starting or shutting down 
    • SOLID GREEN: Radio is in receive mode 
    • FLASHING RED: See Error Conditions below 
    • SOLID BRIGHT RED: Transmitting on PA 
    • SOLID DIM RED: Transmit engaged, but transmit interlocks are not ready. Refer to the SmartSDR documentation for description of the transmit interlocks. 
    • SOLID ORANGE: Transmitting on XVTR port with low power 
    • SOLID PURPLE: Radio is performing a software update 
    • FLASHING WHITE: Radio is performing a reset to factory defaults 
    • OFF: Radio is off 

    When the optional GPS Disciplined Oscillator is installed:
    • SOLID AMBER: Radio is off, GPSDO is powered for stability 
    • FLASHING YELLOW: GPSDO is warming up 
    • SOLID YELLOW: GPSDO is “holdover” mode (has lost satellites) 
    • SHORT FLASH BLUE: GPSDO is locking 
    • LONG FLASH BLUE: GPSDO is in “hold phase” mode 
    • SOLID BLUE: GPSDO is locked

    Hi Vincent, if you have the GPSDO, it indicates that the radio is off, but the GPSDO is powered up. This is normal.

    If you don't have the GPSDO, then you should export your profiles and do a factory reset. If it still happens after the reset, you should submit a help desk ticket.
