1. The air massager is composed of 20 air bags (photo-1) contained in an air pump, an air
tank and solenoids (Photo-2), and foot and leg massaging components and of air hoses
(photo-2) connecting among them, all of which are located under the seat.
2. Air pressured by means of the air pump is supplied to the individual air bags by switching
among the solenoids.
3. In massaging, the process of two steps is repeated; 1) pressing and finger-pressurizing
feet and legs by air bags expanded with filled air and 2) compressing the air bags by
discharging air from the solenoids.

2, Massage motor
This motor rotates to move the massage balls crosswise via the driving belt and gear
box coupled to the motor.
(The motor revolutions is adjustable in three steps so that the massaging frequency
can be changed over to approximately 10,15,20,25 and 30 cycles/minute.)
(When tapping, shiatu and stretching the backbone line, the massage ball position
can be changed over in three steps after starting the massagemotor.)
(Massage ball width approximately 70,85,100,115 and 130 mm.)
3, Strength motor
This motor rotates to transmit its rotating torque to the shaft screw via the driving
belt, whereby the massage unit is moved forward, and backward and the massage
balls is moved forward and backward.
(This motor rotates clockwise and counterclockwise to thereby move the massage
unit forward and backward.)
(When tapping, massage, shiatu and stretching the backbone line, the massage unit
position can be changed over in five steps after starting the strength motor.)
4, Elevation motor
This motor rotates to transmit its rotating torque to the gear of right and left of a
massage unit the driving belt.
The gear is included in right and left of a back frame. It has geared with the gear of
right and left of a massage unit.
This motor rotates, a gear on either side rotates and a massage unit moves up and
down in the gear top of a back frame.
(This motor rotates, clockwise and counterclockwise to thereby move the massage
unit move up and down.)
(When stretching the backbone line, the massage ball is moved up and down.)

Shoulder Gripping & Massaging
With the aid of a massage hand unit with a joint which moves freely like a thumb, a
massaging technique called "Grip/Grasp/Massage/Knead" for gripping and massaging
the muscles of shoulders has been reproduced.
This massaging technique has been reproduced by way of gripping the shoulders from
above while projecting the massage hands greatly together with a massage unit at the
back (maximum projection of massage hands: approx. 160mm).
Operation of Shoulder Gripping & Massaging
There are two large massage hands and two small massage hands at both ends of the
right and left massage arms. The small massage hands have the structure to move freely.
The massage hands move from side to side according to the operation of massage motors.
When the distance between the massage hands becomes narrower (the massage hands
move inwards), the massage hands move so that the clearance between the large
massage hands and the small massage hands becomes narrower.
Operation of shoulder gripping and massaging: Shoulder position is first measured, and
the massage hands project forward greatly only at the shoulder position and "grip and
massage the shoulders".
*The "shoulder gripping and massaging" function does not work on the back or the waist.

Operation of Stiffness Detecting Sensor
HEC-DR5000
The sensor employs two types of sensors; an photo sensor and an electrical skin resistance
sensor for monitoring two physiological factors (pulse rate and perspiration respectively).
If stiffened position is subjected to stimulation of massage, the pulse rate and perspiration
will change accordingly. The sensor monitors such change in those two factors.
(GENERAL)
Perspiration Pulse rate
When stimulated
and felt "stiffened"
Perspiration
increases
Pulse rate
increases
Sensor
Detection
A stimulation given to the stiffened or
sore muscle will cause vital reaction
considered to represent a change in
sensation such as better feeling with
comfortable pains. Monitoring such vital
reaction (perspiration and/or change in
pulse rate) concurrently enables
determination of the effectiveness of the
stimulation given.
STIFFNESS
The stiffness determined by a change in perspiration and
pulse rate monitored will be indicated in real time on a level
meter of a remote controller.
1;When relaxed, the perspiration tends to decrease.
2;When in normal condition, each physiological
Stiffness display
Indicates stiffness in real time by
monitoring fingers for any change
in perspiration and pulse rate
during acupressure massage.
RELAX HIGHT
parameter shows less change.
3;When felt stiffened, the perspiration as well as pulse rate tends to increase.
4;When feeling a pain, the perspiration significantly increases and the pulse rate tends
to increase.
In the massage position display, the position where stiffness is detected (=the point needs
to be massaged) will be displayed.
STIFFNESS
Massage position display
Point that may be massaged.
Position where stiffness is detected
Indicates positions where the sensor detects
stiffness by monitoring perspiration and pulse rate that will
change when better feeling is given through stimulation
by massage.

Operation of Body Contour Sensor
HEC-DR5000
Detects a pressure applied to the massasing balls for automatic adjustment to their best position.
Detects a pressure applied to the massasing balls for measuring spine curving to find out body
contour and shoulder position.
Corrects the positions automatically if the posture varies
when reclining a seat.
(When the shoulder position is being adjusted, the "SHOULDER"
display of the remote controller turns ON with the "UP( )/DOWN ( )"
display kept blinking.
Adjustment is finished when the "Shoulder Set" lamp turns ON, which will
then turn OFF after the shoulder position adjustment is completed.)
Detects pressure applied to the massaging balls that depends on spine
curving, and determined its body contour and shoulder positio
n.
*
Unless the massaging balls receive a body weight pressure from user for a certain time
during sensor automatic course or automatic course, the operation will discontinue with
the massaging balls retracted.

Error message indication (in Service Mode)
HEC-DR5000
(GENERAL)
*Abnormal indications detected during operation are stored in a memory up to
seven. Seven abnormal indications stored can be confirmed in the service mode
(Older indications than the seven abnormal indications will be deleted sequentially).
To change over to the service mode, turn ON the POWER switch at the rear of the massager
while simultaneously pressing the OPERATION ON/OFF on a remote controller.
When the "FINE" button is pressed three times with the OPERATION ON/OFF kept pressed,
the massager is placed in the service mode.
(When the massager is placed in the service mode, four blue lamps at the WHOLE BODY
SENSOR AUTOMATIC COURSE come on).
To reset the service mode, turn OFF the POWER switch.

Up to seven abnormal indications are stored in a memory. In case of less than seven, since
there are not any abnormal indications, some of the seven STIFFNESS indicators are lit
alternatively to indicate the state that abnormalities are not stored.
