Precautions
Before operating the EWI4000s, please be careful of the following:
• As there is a Vibrato sensor in the Mouthpiece, when you expert pressures on the mouth-
piece while playing, do not bite the mouthpiece too hard with your teeth, as this may
damage your EWI4000s. Use the Mouthpiece Cover after using or while carrying the
EWI4000s.
• Always touch the Earth Plate and Octave Shift Rollers when playing and editing sounds.
Each of touch sensors uses the performer’s body as the earth.
• It is important to keep the mouthpiece clean. The mouthpiece comes in direct contact with
the inside of the performer’s mouth, so take care to keep it clean before, during, and after
using the EWI4000s. You can clean its outer surface with disinfectant alcohol.
How to install the Batteries
Please use four (4) ALKALINE AA or re-chargeable AA
batteries only. Refer to the drawing for correct battery
installation.
Select “BATT.” on the Power Switch, when us-
ing batteries. For prolonged battery life, select
the “OFF” position on the Power Switch when
you’re finished playing.
In the event that battery power becomes low,
the dot on the LED of the Program/Data display
will start blinking. Change the batteries as soon as the dot on the LED starts blinking.
Install the batteries very carefully - paying close attention to the direction of them (+/
- sides as shown)
Remove the batteries when you are not going to be using your EWI4000s for an ex-
tended period time. Don’t use the different type batteries at the same time.
AC adaptor
You can also use the AC adaptor “MP-9 (Optional), instead of batteries.
Connect the “MP-9” to the “DC IN” jack of the EWI4000s and select “DC” on the
Power Switch.
