Amber light on power switch

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
