CLEANING METHOD OF CUFF
After cleaning the cuff with a neutral detergent, lightly rinse it withwater and let it dry in the air. Hard rubbing or washing in a washingmachine will cause air leakage. Also, be careful not to get water into
the air hose.

For proper measurement of blood pressure• If the cuff is to be deflated quickly, depress “POWER” switch.
• The attached cuff is suited for a wrist circumstance of 13.5cm to19.5cm.
• When attaching the cuff, the body of a blood pressure monitor
should be placed on the inside of your wrist.
• Self measurement is no therapy! In no case may you change thedosage 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 tomeasurement.
• 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 each day.
• Do NOT be impressed by the results of one measurement. Keep arecord of blood pressure variations. Many readings tell a story.
• Emotional stress may tend to cause pressure to rise.

• 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 worrisome orirritated 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 for ensuring
proper measurement of blood pressure. Wind the cuff around thewrist and tighten it so that one finger may be inserted between thecuff 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.
• Measure blood pressure with a relaxed and quiet posture. Keepthe center of the cuff at the level of your heart, and do NOT moveyour arm or talk during measurement.
• Do NOT keep on measuring so many times, as your arm will havebuilt up congestion of blood, and you will not get a valid reading.

GENERAL REMARKSPRECAUTION FOR USE AND MAINTENANCE
Precautions for use

Nature and frequency of maintenance:• If you suffer from heart disease, high blood pressure or other circulatory disease, please consult your doctor first.
• If you feel abnormal pressure of the cuff during use or any otherirregularity, reduce the pressure by immediately switching off thepower or removing the batteries and consult the sales outlet wherepurchased.
• If you think the measured value is abnormal or if measuring makes
you feel unwell, discontinue use and consult your doctor.
• Measurement of blood pressure may not be possible for someone
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 should be allowed.
• The memory is erased if the batteries are removed for replacement, etc. and a record should be kept of any necessary data.

This products is designed for use over an extended period of time;
however, it is generally recommended that it be inspected every twoyears to ensure proper function and performance.

Protect the nature environment:
Please help protect natural environment by respecting national and/or local recycling regulations when disposing of the batteries andthe products at the end of their useful lives.

Reference European standard:This products complies with EC instructions 93/42/EEC (MedicalDevice Directive) and with the following standards: EN 1060-1 : 1995
“Noninvasive Sphygmomanometers, Part 1 General Requirements”
and EN 1060-3 : 1997 “Noninvasive Sphygmomanometers, Part 3
Supplementary Requirements for Electromechanical Blood-Pressure
Measuring Systems”.

Precautions for maintenance
Manufacturer:• Do NOT store the blood pressure monitor where it will be exposed
to direct sunlight, high temperature (over 60˚C), low temperature(below –20˚C), high relative humidity (over 95%) or in a dustyplace.
• Do NOT expose the blood pressure monitor to under force or vibration, 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 cloth moistened with Sterilizing alcohol or a neutral detergent, and then wipe
it with a dry cloth. Do NOT use thinner or benzene.

2. Attaching of Wrist Cuff

Wrist cuff

Wrap the cuff around yourwrist securely.

Open the wrist cuff as the figure.

Wrap the cuff around your wrist securely so that there is nospace between the wrist and cuff with the edge of wrist cuff
pulled.

Turn left hand palm upwards and wrap the cuff around the wrist
so that the display is placed on the side of palm.

When a pulse is detected, the pressure value moves to the lower
side of the display. At this time the mark “Q” flashes and buzzer
beeps.
If the inflation is insufficient at a pressure of 180mmHg, thereinflation is automatically made to a pressure of 210, 240, and
280mmHg until inflation is suitable for measurement. This unit
cannot be inflated over a pressure of 280mmHg.

Press the “START” switch.
The unit is inflated when the “START” switch is pressed.
