If using batteries, make sure that each battery is securely in place and in the correct orientation. It is also
possible that the batteries have run down, so you should obtain a new set of batteries.

default values if the effect type is changed. If precise settings, you should a note of those settings to use
again.
Refer to: “Effects settings” (p. 59)
