[time-nuts] 10811 warmup (Jason Rabel)

Made'm red just for ya in the updated 10811 manual

DO NOT OPERATE THE OVEN CIRCUITS WHEN THE OVEN MASS IS OUTSIDE OF THE OSCILLATOR
INSULATED HOUSING. DOING SO WILL OVERHEAT THE OSCILLATOR CIRCUITS INSIDE THE
OVEN MASS AND CAUSE PERMANENT DAMAGE. ALL OVEN TEST POINTS ARE AVAILABLE WITH
THE OVEN MASS AND OVEN CONTROLLER CIRCUIT INSIDE THE HOUSING.
WHEN OSCILLATOR COVER AND INSULATOR ARE REMOVED THERMAL FUSE WILL NOT PROTECT
CIRCUIT FROM OVERHEATING.

I am trying to think of why they say this.  I don't see why
you can't power the oven when it is disassembled.  I can see
that it might not reach 80 degrees or might oscillate and
it would be too hot to handle.
