About PSR 740 DSP 3 Band EQ effect:
In owner's manual page 144, DSP 1-4 Type List, there are
two DSP
3Band EQ (MONO) and 2Band EQ (STEREO) effects, which texts tell:

A mono EQ with adjustable LOW, MID, HIGH equalizing.
A stereo EQ with adjustable LOW and HIGH.

How to adjust LOW, MID and HIGH Bands. The manual doesn't say
how to do that and I have not found a way.

Thanks in advance.

Carlos,
I phoned Yamaha and the technician told me it was not adjustable. I'm not certain he is correct, but I couldn't get any real help with it.
