Laser panel

what kind and what so I need to set it at? I messaged the person where I bought it and 3 weeks later he finally got back to me, with nothing. IT ONLY HAS POWER CURRENT INDICATION +10% +1% +0.1% TEST
-10% -1% -0.1%
running off of a apple and just bought a version 1.3.01, of lightburn

Thank you
