Purion display shut off

[RonJ.]

The bike with wheels from the ground.
When turning the pedals by hand with the motor activated the display goes black and after a second its on again.
When biking no problems.
Bosch gen 4 85nm update done.
Is this a known problem or a error?
Somebody else who has noticed this.

Regards Ron

thats normal, I think it knows by hand you are not delivering enough force for pedalling so it doesn't supply power, and shuts down in disgust about its treatment.

Okay,

I noticed after an error 504 and an update to 1.1.2.0
No problem while cycling.
Keep finding it strange that the display then switches off.
