According to Z1 Manual, section 4.1.6 FX Mode
Press MODE + ON to switch to the corresponding FX mode.
⇨ You will notice the ON button's dim backlighting switches from blue to orange.
I can't seem to get this to work, when i press both the MODE+ON button the ON button does not change to Orange (FX Mode).
Is there some settings I need to check for this to work ?
Thank you
