Just to clarify, this appears to say that with auto speedbrake off, spoilers are disabled and you have min spoilers? Dont you have max angle with auto off?

If you were to land without auto speedbrakes armed, they would operate normally when you manually move the speedbrake handle to up.

I have a question; if the 'SPEEDBRAKE DO NOT ARM' light illuminates in flight and the QRH checklist is run, there is no reference to reduced performance on the runway. Is this because the CB has not been collared?
The SPEEDBRAKE ARM/SPEEDBRAKE DO NOT ARM lights are powered through the auto speedbrake CB, so if the CB has popped or has been pulled/collared you won't get any lights. So if the SPEED BRAKE DO NOT ARM light is on, there is power through the CB and therefore power to the spoiler solenoid operated valves.
