GENERAL REMARKS
General Remarks on blood pressure
measurement• Emotional stress may tend to cause pressure to rise.

• If the cuff is to be deflated quickly, depress “POWER” switch.
• The attached cuff is suited for an arm circumstance of 22cm
to 32cm.
• When attaching the cuff, rubber cuff hose should be placedon the inside of your arm on top of the arterial.
• Self measurement is no therapy! In no case may you change
the dosage of medication prescribed by your physician.
• In operation for blood pressure measurement, you should
urinate and should remain relatively still for 10 to 15 minutes
prior to measurement.
• Exercise, eating and drinking, smoking, etc., prior to measurement may affect the results.
• The blood pressure varies constantly throughout the day.
Measurement should be made regularly at the same time eachday.
• Do NOT be impressed by the results of one measurement.
Keep a record of blood pressure variations. Many readings
tell a story.

• Take a deep breath five or six time and then relax before measuring blood pressure. If you are tense when taking the measurement, you will not get a valid reading.
• Blood pressure will be elevated when you are in a worrisomeor irritated state, suffering from lack of sleep or constipation,
or after exercise or a meal.
• Putting on the cuff is one of the most important tasks forensuring proper measurement of blood pressure. Wind thecuff around the arm and tighten it so that one finger may beinserted between the cuff and arm.
• Do NOT measure blood pressure after bathing or drinking.
• When you feel like relieving yourself, you should do so before measuring blood pressure.
• Measure blood pressure where the room temperature is about
20˚C. Do NOT measure blood pressure when it is too cold
(below 10˚C) or too hot (above 40˚C) in the room.
• Do NOT measure blood pressure immediately after drinking
coffee or tea or smoking.

For proper measurement of blood pressure- Eng 3 -English

CLEANING METHOD OF CUFF• Measure blood pressure with a relaxed and quiet posture.
Keep the center of the cuff at the level of your heart, and do
NOT move your arm or talk during measurement.

• Do NOT keep on measuring so many times, as your arm will
have built up congestion of blood, and you will not get a validreading.

PRECAUTION FOR USE AND MAINTENANCE
Precautions for use

Precautions for maintenance• If you suffer from heart disease, high blood pressure or othercirculatory disease, please consult your doctor first.
• If you feel abnormal pressure of the cuff during use or anyother irregularity, reduce the pressure by immediately switching off the power or removing the batteries and consult thesales outlet where purchased.
• If you think the measured value is abnormal or if measuringmakes you feel unwell, discontinue use and consult yourdoctor.
• Measurement of blood pressure may not be possible forsomeone with a weak pulse or arrhythmia.
• Congestion, swelling, etc. may occur in some people.
• If blood pressure is measured repeatedly, an accurate result
will not be achieved. An interval of about 10 minutes shouldbe allowed.
• The memory is erased if the batteries are removed for replacement, etc. and a record should be kept of any necessarydata.

• Do NOT store the blood pressure monitor where it will be
exposed to direct sunlight, high temperature (over 60˚C), lowtemperature (below –20˚C), high relative humidity (over 95%)
or in a dusty place.
• Do NOT expose the blood pressure monitor to under force orvibration, or drop it.
• Remove the battery/batteries when not in use for a long period.
• Do NOT disassemble the apparatus.
• Do NOT bend the cuff or air hose unnecessarily.
• NEVER wipe the blood pressure monitor with thinner or benzene, as they may damage it.
• When the monitor is very dirty, wipe it clean with a clothmoistened with Sterilizing alcohol or a neutral detergent, andthen wipe it with a dry cloth. Do NOT use thinner or benzene.

Nature and frequency of maintenance:
This products is designed for use over an extended period oftime; however, it is generally recommended that it be inspected
every two years to ensure proper function and performance.

PREPARATION FOR MEASUREMENTS
1. Installing battery

2. Inserting hoses

Bulb hose
Cuff hoseTake off the battery cover at the back of the unit by sliding itas shown.

Insert the cuff hose and bulb hose into the hose connector.

Install a 9V battery (6F22, 6LR61) taking care for the polarity.

- Eng 5 -EnglishProtect the nature environment:3. Attach the cuff

The cuff hose should be placed on the inside of your arm asfigures.
The cuff should be wound so that one finger can be inserted
under the cuff.

Wind the arm cuff around the left upper arm tightly where thebottom edge of the cuff is positioned about 1 – 2cm (about 1inch) above the elbow joint.

1 – 2cm
When you will wind the cuff, please wind the cuff on the skindirectly if possible.
(If measurement is made by rolling the shirts or jacket up overthe arm, this will constrict the upper arm and prevent accuratemeasurement)

Rest the elbow on a table so that the section of the upper arm
is at the height of the heart. Relax the lower arm across thetable and remain still.
Make measurements in either a seated or reclining posture.

3. Pressurize the cuff
SYSTOLIC mmHg DIASTOLIC mmHg

Pressurize the cuff bypumping the bulb until you
have a reading of approximately 30 to 40 mmHg
PULSE/minhigher than your regularsystolic blood pressure.
Note: At pressure of 140, 170, 200, 240mmHg, the buzzer beeps
