NRDK - Why not mention the trick? The point is that every little helps to make the HMI more error-tolerant. The more error tolerant a system is, the less of a "big deal" it is to carry related drills out near the surface.
If you imagine that "stick to the EOP" is all that is required from a manufacturer, you don't understand human nature, which is to err.
Sorry but if you suspect that this tiny piece of information will distract you during execution of an emergency drill, I don't think you should be flying.
Collective - so that is fine provided the temperature doesn't exceed 1100!
