ARC VT-130SE owners

Hi, I just got a SE version with the meters, but the meters don't light up ! Is it supposed to ? what can be wrong. ? Maybe the light bulbs are out ? Or is there an internatl switch to activate ?
thanks for our help.
the meter lights just came on y itself after 1hr. of amp use!
I did not touch anything. did it need to be charged?
anyone with similiar experience? normal?
Just call ARC and ask them...
If I am not mistaken, the left knob controls illumination. Try turning it all the way.
