34461A Front Panel Power Lamp (two colors)

I notice that the 34461A front panel power lamp is bi color.  When plugged in and off, it shows amber, and when the DMM is powered up, it turns green.

It would be fantastic if the voltage reference remained heated 24/7 when plugged in like hp did with the oven oscillators in counters and other instruments.  Does the LM399 heater power remain on at all times?

If not, what does the bi color lamp indicate?

I could not find an indication in the manual, apology in advance if the answer is there.
