Reply to DJTT UV Knobs and DJM 600

Hi, i just received my DJ TT UV Knobs, i put them on my DJM 600 and to my surprise
all of the markers are upside down.:eek:
*(mind you i did email djtt if they would fit, they said it'd be fine as they have a djm500 in their office)

I looked under the knob and it seems the "halfmoon shape" is the opposite of what it it on the 600, so it does fit but the wrong way..

Can anyone help me? I use this mixer for raves, and many djs go on this... I need this to be straight!
*(i emailed DJTT, but no response...)
