Hello,

regarding documentation for accessing Service Desktop mode button 3 need to be pressed as soon as the SInumerik version is displayed. 

I tried severial times but if I press or if I hold button 3 nothing happens. I can only press button 1 and Thin Client boot loader is displaed as shown in enclosed pictures, but there is no option to select for booting PC in Service Desktop mode. 

How to proceed to access Service Desktop on this version of device.

Thanks.
