E07 secondary brightness adjustment

Hey everyone, just bought a fireflies e07. I would like to adjust the brightness of the secondaries by the three adjustment potentiometers. Before I do, has anyone else done this and can I screw something up by doing this? Does one of the potentiometers adjust brightness of the switch leds.

No adjustment for the switch leds

Be careful. They can break easy.
