Vintage Synth Repair

Thanks, what does this mean practically ?
I currently set them both to center position, and the sampler works fine. I just haven't managed to find any calibration instruction for the power supply unit. Can you think of any way to calibrate it ? or is it safe to use it this way ? (trimpots to center)

Thanks!
