SP808 Virtual Analog Synth - how to activate Delay/Chorus?

[NE555]

Hi guys!
I have bought a Sp808 about two weeks ago and all is fine yet...except one thing I absolutely cannot find a solution for:

When using the effect-patch "VA Synth", there is the option to turn the 2 effect-slots "delay" and "chorus/flanger" on.
The default setting is always "off" and I can't find out, how to turn them on.
I am using the patch with the step modulator and I want to use the delay/chorus section, to improve the synth's sound.

I am digging the manual over and over again - but all it says is, that these sections are the only 2 sections of the "va synth" effect, which can be turned off individually.
But no words about the "how to" turn them on or off.

Any help would be really appreciated. Thanks a lot in advance!

Yeah...topic closed, because I found it out by myself. The solution was pretty simple. All I had to do was to turn the jogwheel at the first FX-Setting screen. After switching the cursor with the left/right/up/down buttons to the delay and the chorus section, I could turn those section on/off via jogwheel.
Man...I'm happy now
