General information
Product Features
◇AUTO Mode of Measurement
Perform automatic measurement (AUTO measurement).
◇AUTO3 measurement mode
Perform AUTO measurement three times in a row, calculate the average of the measurement results,
and then display the reliable blood pressure value according to AUTO measurements.
◇MANUAL Mode of Measurement
Measurement can be performed using a stethoscope. The following deflation rates can be selected: 2.5,
3.5, 4.5, 5.5, and 6.5 mmHg/s.
◇Regular and Large Size Cuffs
The regular size cuff will accommodate an upper arm circumference range of approximately 22 to 32
centimeters and the large size cuff will accommodate that of approximately 32 to 42 centimeters.
◇AC adaptor and built-in rechargeable battery
The device can be powered by either an AC adaptor or built-in rechargeable nickel metal hybrid (NiMH)
battery.
◇Backlight function
If the buttons of this device are operated, the backlight switches on.
◇Automatic re-inflation
During measurement, the cuff is automatically inflated to the set preset pressure value. If the set preset
pressure value was low and insufficient for the measurement, deflation of the cuff starts, and then
inflation is carried out again to a pressure higher than the preset value.
◇Memory function
If measurement ends in AUTO measurement mode or AUTO3 measurement mode, the measurement
result is saved to memory automatically. The memory can store up to 30 measurement results.
◇Irregular pulse wave rhythm mark
If the pulse wave interval is not constant, the Irregular pulse wave rhythm mark [ ] appears.
The Irregular pulse wave rhythm mark may appear regularly even when the patient is measured in a
calm condition.
Further investigation may be necessary for the determination of the actual cause.

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 auscultation. If
the artery is compressed by the pressure of a tourniquet (cuff), the artery causes a pulsation that matches
the pulse, which becomes the pulsation of the internal pressure of the cuff. The size 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 size of the pulsation that appears when the cuff interior pressure has been gradually
changed. Furthermore, with auscultation, a stethoscope is used to detect the Korotkov sounds generated
when the cuff interior pressure is gradually changed and measure the blood pressure.
Indication for use
This product is intended for noninvasive measurement of systolic and diastolic blood pressure,
determination of pulse rate in adults in a hospital. The product is not designed for neonatal use. Please
consult with the doctor or physician to use this product to take blood pressure of child or person in
pregnancy or under pre-eclamptic condition. This device is for medical staff use.

Precaution and contraindication
• Please carefully check patient’s conditions in advance to the measurement if he /
she is under dialysis therapy or on anticoagulants, antiplatelets or steroids. Use of
this instrument under such conditions could cause internal bleeding.
• Do not use this product along with implantable and wearable medical electrical
equipment such as pacemaker, defibrillator, or electrocardiographic monitor.
• This product is not also intended to be used with HF surgical equipment.
• Do not use this product in an explosive environment such as near flammable
anesthetics or inside oxygen chamber.
• The system may fail to yield specified measurement accuracy if operated or stored
in temperature or humidity conditions outside the limits stated in the specifications
section of this manual.
• Do not use cuffs or accessories other than those specified by the manufacturer.
Otherwise, correct measurement readings cannot be obtained.
• Use of this product in areas near mobile phones, microwave ovens or other devices
with strong electromagnetic field may cause malfunctions.
• Do not apply the cuff over wounded arm, arm under an intravascular access or
therapy or an arterio-venous shunt, or arm on the side of a mastectomy. Otherwise
injury may be resulted.
• Make sure that inflation of the cuff is not causing prolonged impairment of blood
circulation. Also, be cautious about temporary loss of the functions of any other
medical equipment if any monitoring equipment is used on the same limb with the
blood pressure measuring cuff.
• To avoid harmful injury due to interfered blood flow from cuff inflation,
- Make sure that AIR TUBE is not kinking before measurement. Otherwise, cuff
inflation may not be conducted properly and prolonged, and
- Do not make measurements repeatedly.
• To avoid any possibility of accidental strangulation, keep this product away from
children and do not drape AIR TUBE around your neck.
• Because the product includes precision parts, avoid extreme temperature variations,
humidity, shock, dust, and direct sunlight. Do not drop or strike the product. Make
sure not to expose it to moisture. This product is not water resistant.
