Do not bite the MOUTHPIECE too hard as this may damage the vibrato sensor. Use the mouthpiece
cover after using or while carrying the EWI4000s.
y
Always touch the GROUNDING PLATE and OCTAVE SHIFT ROLLERS when playing and editing
sounds. Each of touch sensors uses the performer’s body as the ground.

Keep the MOUTHPIECE clean before, during, and after using the EWI4000s. You can clean its outer
surface with disinfectant alcohol.

batteries. To prolong battery life, select the “OFF”
position on the Power Switch when you’re finished
playing.

Remove the batteries when you are not going to be
using your EWI4000s for an extended period time.
