Spdif (Toslink) does not fit in vero socket


Is there an instruction how to remove the cover from the Vero?
I have a Toslink cable with a steel connector at the end, so trimming the cable is not a option.

If I can remove the top cover I can drill a nice hole that will make my spdif fit nicely.

Or any other suggestions?
I will not be able to replace my current optical cable…
