Operation principles
This device is equipped with two types of measurement. AUTO measurement measures the systolic
blood pressure, diastolic blood pressure, and pulse rate automatically using the oscillometric method.
With MANUAL measurement, an operator uses a stethoscope to measure blood pressure using
auscultatory method. When the artery is compressed by the pressure of a cuff, the artery generates a
pulsation synchronizing with the pulse, which becomes the pulsation of the internal pressure of the cuff
(cuff pressure). The amplitude of the pulsation changes in accordance with the magnitude correlation of
the blood pressure and the cuff pressure. An oscillometric blood pressure monitor determines systolic
and diastolic blood pressures based on the change pattern of the amplitude of the pulsation that appears
when the cuff pressure is gradually changed. Furthermore, with auscultatory method, a stethoscope
is used to detect the Korotkov sounds generated when the cuff pressure is gradually changed. The
blood pressure is determined according to the pressure values at appearance and disappearance of
the Korotkov sounds.
Intended purpose and Indication for use
This product is intended for noninvasive measurement of systolic and diastolic blood pressure by
automatic measurement, with applying the cuff on patient’s upper arm, with oscillometric method
and manual measurement with auscultatory method and determination of pulse rate in professional
healthcare facility. This product is not designed for neonatal use. Please consult with the doctor or
physician to use this product to take blood pressure of person in pregnancy or under pre-eclamptic
condition. The automatic measurement of blood pressure is intended to be taken for adults only. For
taking blood pressure measurement of children with auscultatory method, please consult with the
doctor or physician.
This device is designed for medical staff use in medical institutions. The product is not intended to be
used either outside the healthcare facility, during professional transportation of a patient outside the
healthcare facility or home healthcare environment.

BATTERY MARK flashes in the segment LCD when the battery
charge is low.
Only a few more measurements remain before the battery runs down.
Stops flashing and becomes steady. The battery is exhausted
and must be recharged.
Measurement cannot be made.
Battery life
Life of the rechargeable NiMH battery is approximately 2 years. However it may vary depending on
operating conditions. Replace the battery when BATTERY MARK is displayed often or when frequent
charging of the battery becomes necessary.
Tips on prolonging the battery life
The device is powered by AC ADAPTOR when it is connected; the installed
battery is not used if AC ADAPTOR is connected.
• Remove the battery when operating the device with AC ADAPTOR for extended
period of time or when the battery does not need to be charged.
• Avoid charging the battery if it is not completely exhausted.
Do not forcibly remove the battery or pull out the plugs holding
cords and cables.
Use manufacturers dedicated AC adaptor and battery only.
Contact your supplier if they become damaged or need replacing.
The device goes to energy saver mode when it is left turned on and not operated
for approximately 3 minutes. The mark will be displayed for an hour and then
disappear. Make sure to turn off the device by pressing "
" side of MAIN
POWER SWITCH down after each use especially when the device is powered by
the battery.
The device activates from sleeping mode when either START/STOP BUTTON or SET/MEMORY
BUTTON is pressed. It is recommended to activate the device by pressing SET/MEMORY
BUTTON since the device could start inflation if START/STOP BUTTON is pressed. Press
START/STOP BUTTON again and stop inflation if the cuff is not wrapped around arm.

PRESET PRESSURE
Turn on the device by pressing " " side of MAIN POWER SWITCH.
Push the MODE SELECTOR downward and set to "AUTO".
See page 13 for "MANUAL" measurement.
Set the initial inflation value with the PRESET PRESSURE CONTROL.
Select the pressure approximately 30 to 40 mmHg above expected
systolic pressure.
Pressure can be set between 100 mmHg and 280 mmHg. Cuff is not
inflated when the knob is set below 100 mmHg, "PUMP OFF".
Set the pressure at 180 mmHg if patient's systolic pressure is
difficult to predict.
The cuff will be re-pressurized to a higher value if the preset
pressure is too low for blood pressure to be taken during cuff
deflation.
Apply the cuff to patient's arm.
Choose the right size of cuff for your patient.
Find a chair and a table so that the patient can be comfortably seated with patient’s back
and arm supported. Legs should not be crossed and feet kept flat on the floor.
The lower edge of the cuff should be about 2 to 3 cm
above the inner elbow and the AIR TUBE should be on
the inner part of the arm over the brachial artery.
Press the surface of the cuff to make sure that the hook
and loop fastens securely.
The cuff should be wrapped loosely enough so that two fingers can be placed
between the cuff and patient's arm. If the cuff is wrapped more tightly or loosely
than this, inaccurate blood pressure readings may result.
If your patient is wearing a shirt that might restrict circulation in his/her upper
arm or he/she rolls his/her sleeve up over the upper arm, the blood flow could be
restricted, preventing accurate measurement.

Blood pressure (mmHg)
Systolic Diastolic
Time
Blood pressure is the force exerted by the heart in pumping the blood through the arteries and the
resistance by the veins to this flow.
Blood pressure varies all the time, influenced by mental and physical factors and is
never constant.
In general, blood pressure is highest during the working hours and gradually decreases during the
afternoon and evening hours. It is low during sleep and increases at a relatively fast rate after arising
from bed.
Causes for Changes in Blood Pressure
• Body movement • Conversation • Mental Tension • Nervousness
• Emotions • Eating • Drinking Alcohol • Smoking
• Measurement posture • Recent Urination or Bowel Movement • Room temperature
• Changes in the surroundings such as movement or noise, etc.
Blood pressure measured at hospital or clinics tends to be higher than when it is
measured at one's home, this symptom is known as "White Coat Syndrome".
Being in a hospital could cause mental tension and therefore lead to higher blood pressure than that
taken under relaxed condition at one's own home.
Judgment such as a change of dosage of a drug based on measurement results
should not be made by patients on their own without professional consultation.

NOTES ON BLOOD PRESSURE

- 20 -
Blood pressure should be taken after approximately five minutes of rest, under
relaxed conditions and in a quiet environment.
Exercise, eating, drinking alcohol, smoking and other activities that effect blood
pressure should be avoided prior to measurement.
Cuff measurement position should be at the height of the heart to obtain correct
measurement results. If the cuff is lower (higher) than the heart, the measured
reading tends to become larger (smaller).
There should be no speaking or moving during blood pressure measurement.
Otherwise correct measurement results cannot be obtained.
The ambient temperature should be approximately 20˚C for blood pressure
measurement.
Any shirt or accessories that might restrict circulation in the upper arm should
be taken off for blood pressure measurement.
Sleeves rolled up over the upper arm will restrict the blood flow and lead to
inaccurate measurement.
Measurement of blood pressure should not be repeated immediately since
congestion of blood could result in inaccurate measurement. There should be at
least 5 minutes between measurements.
