Do I need HEQ5 handset to maintain alignment?

[ennui2342]

I've knocked up a EQDIRECT cable connecting straight to the RJ-45 socket on my HEQ5. I understand that I should do my 3-star alignment before using it, as no software on my Mac will allow me to do this, but after I then remove the handset and plug in my laptop, is the alignment lost?

Just wondering whether I need to build another cable using the RJ-11 socket on the handset? I was avoiding this as I was getting a 8.4v TX from it which whereas the RJ-45 direct connection was at a 5v level.
