Make a plain paper photocopy of the front of the unit, or mark the exact positions of the center laser and the 3 outer lasers on a piece of paper if you don't have a copier. Place the photocopy up at several meters distance. I used 8 meters which works well for me. Project the center laser with the crosshairs and the 3 outer lasers and align the center laser and its crosshairs as good as possible.
The 3 outer laser dots should now perfectly align with those of the photocopy. If they do then congrats your unit is collimated well and you can use it to collimate a telescope. There's no need to continue reading this page.
If they do not then you may want to align them. Like in this projection the
lower right laser is clearly quite off its target.
The laser unit is in the aluminium colored cylinder. It is held in place at its
back with 3 grub screws in the red colored cylinder. These grub screws can be
adjusted with a hex key like this:
After adjustment mine looked like this :

The caps on the back of the 3 laser units unscrew just like the one of the
battery unit. You have to cut through their safety stickers though which
may void your warranty so check with Hotech if this is a problem for you.
