* SAFETY INSTRUCTIONS
PRECAUTIONS DURING SERVICING
1. Parts identified by the A symbol are critical for safety.
,^ Replace only with parts number specified.
2. In addition to safety, other parts and assemblies are
specified for conformance with such regulations as those
applying to spurious radiation.
These must also be replaced only with specified
replacements.
Examples: RF converters, tuner units, antenna selector
switches, RF cables, noise blocking capacitors, noise
blocking filters, etc.
3. Use specified internal wiring. Note especially:
1) Wires covered with PVC tubing
2) Double insulated wires
3) High voltage leads
4. Use specified insulating materials for hazardous live parts.
Note especially:
1) Insulation Tape
2) PVC tubing
3) Spacers (Insulating Barriers)
4) Insulation sheets for transistors
5) Plastic screws for fixing microswitch (especially in
turntable)
5. When replacing AC primary side components (transform
ers, power cords, noise blocking capacitors, etc.), wrap
ends of wires securely about the terminals before soldering.
6. Observe that wires do not contact heat producing parts
(heatsinks, oxide metal film resistors, fusible resistors,
etc.).
• INFORMATION
7. Check that replaced wires do not contact sharp edged or
pointed parts.
8. Also check areas surrounding repaired locations.
9. Use care that foreign objects (screws, solder droplets, etc.)
do not remain inside the set.
SAFETY CHECK AFTER SERVICING
Confirm the specified insulation resistance between power
cord plug prongs and externally exposed parts of the set is
greater than 10 M ohms, but for equipment with external
antenna terminals (tuner, receiver, etc.) and is intended for
[C] or [X] , specified insulation resistance should be head
phone jacks, line-in-out jacks, etc. more than 2.2 M ohms
(ground terminals, microphone jacks).
PRECAUTIONS FOR LITHIUM BATTERY
The lithium battery may explode when heated excessively.
[OBSERVE THE FOLLOWING WHEN REPLACING]
• replace with the same make and type only.
• Use soldering iron in "recommended way" only.
• Place battery in correct polarity.
• Do not short the terminals.
• Do not recharge battery.
• Do not dispose of battery in fire.

(2) MOUTHPIECE: Hold the mouthpiece gently in your mouth
and blow in. Do not bite with your teeth.
(D LIP: The pitch, tone, and volume change according to the pres
sure applied to the mouthpiece. Vibration effects including vi
brato, growl/wow-wow, tremolo, and PWM can be obtained by
applying pressure in short, quick movement.
(4) BREATH: Blow in here. Never suck. The strength of breath
changes the pitch, tone, and volume. Do not insert needles, pins,
liquid, or other foreign substances into the hole, as this will result
in malfunction.
(D CABLE CLUTCH: Attach the multi cable here.
<D CONNECTOR: Insert the plug of the included multi cable here.
® TOUCH PLATE BASE: This is the base on which the touch
plate, including the bender and glide plate, is mounted.
® This is the TOUCH PLATE BASE POSITION ADJUST
SCREW. Move the touch plate base forward or backward to find
a position in which it can be operated comfortably with the
thumb of the right hand.
(§) This is the GLIDE PLATE. A glide or portamento effect can be
produced by touching the glide plate and the earth plate (D) with
the right thumb.
© This is the BEND DOWN PLATE. Touch it along with the
earth plate (D) with the right thumb to lower the pitch.
© This is the EARTH PLATE. Always keep your right thumb on
the plate when you are playing.

plate (D) with the right thumb to raise the pitch.
® SLING MOUNT: Hang the EWI1000 on a slinger (included) to
make playing easier.

shifted over 8 octaves. This roller also uses touch sensors. The
range is "standard" when the "II" position is touched with the
left thumb. Always touch this roller while playing.
8 This is the touch sensor sensitivity adjuster. It has already been
adjusted at the factory so do not touch it. If adjustment is neces
sary, refer to the section entitled "Adjustment of Touch Sensor
