Parameter left & right buttons on the Pioneer DJ XDJ-XZ for control key range in Serato ?

Hi,

In the Serato Pioneer DJ XDJ-XZ Quick-Start Guide (page 7/9 - Pitch Play), it’s explained :

« There are 3 key ranges to choose from and To toggle between key ranges press the Parameter left & right buttons. »

It’s said also « Pressing Parameter left & right while holding SHIFT will shift up or down a single semitone. »

My question : where is the Parameter left & right buttons on the Pioneer DJ XDJ-XZ for control key range in Serato ?

Thanks in advance for your answer.

Regards,

Pascal.
