Changing from USALS to Diseqc 1.2

[Stevemo]

Hi all,
I've decided to learn how to set up my dish motor as Diseqc 1.2 as I want to drop USALS as I've read it isn't as accurate. I've got a STAB HH90 motor and the dish angle is very confusing as it is a drastic change from the USALS angle.
Diseqc tells me to put the angle to: Dish Angle - (45 - latitude)
=24.62- (45-46)
=25.72

The other issue is that I can't fit my head between the dish and the motor to read the direction it is pointing! I have read to use Usals to get my close but I'm not sure this is the case.

Please provide some tips on how to get my signal back using Diseqc.

Thanks, Steve
