Introduction
Important Safety Information
•Remove the arm cuff if it does not start deflating during a measurement.
•DO NOT use this monitor for any purpose other than measuring blood pressure.
•During measurement, make sure that no mobile device or any other electrical
device that emit electromagnetic fields is within 30 cm of this monitor. This may
result in incorrect operation of the monitor and/or cause an inaccurate reading.
•DO NOT disassemble or attempt to repair this monitor or other components. This
may cause an inaccurate reading.

monitor. This may damage this monitor.
•DO NOT use this monitor in a moving vehicle such as in a car or on an aircraft.
•DO NOT drop or subject this monitor to strong shocks or vibrations.
•DO NOT use this monitor in places with high or low humidity or high or low
temperatures. Refer to section 9.
•During measurement, observe the arm to ensure that the monitor is not causing
prolonged impairment to blood circulation.
• DO NOT use this monitor in high-use environments such as medical clinics or
physician offices.
•DO NOT use this monitor with other medical electrical (ME) equipment
simultaneously. This may result in incorrect operation and/or cause an inaccurate
reading.

injury by interrupting blood flow.
•To unplug the air plug, pull on the plastic air plug at the base of the tube, not the
tube itself.
•ONLY use the AC adapter, arm cuff, batteries and accessories specified for this
monitor. Use of unsupported AC adapters, arm cuffs and batteries may damage
and/or may be hazardous to this monitor.
•ONLY use the approved arm cuff for this monitor. Use of other arm cuffs may result
in incorrect readings.
•Inflating to a higher pressure than necessary may result in bruising of the arm
where the cuff is applied. NOTE: refer to “If your systolic pressure is more than
210 mmHg” in section 3 for additional information.
•Read and follow the “Correct Disposal of This Product” in section 11 when
disposing of the device and any used accessories or optional parts.
AC Adapter (optional accessory) Handling and Usage

2.1 Installing Batteries
1. Push down on the hook of the battery
cover and pull downward.
2. Insert 4 “AA” batteries as indicated in
the battery compartment.
3. Close the battery cover.
•When the “ ” symbol flashes on the display, it is recommended you replace batteries.
•To replace batteries, turn your monitor off and remove all batteries. Then replace with
4new batteries at the same time.
•Replacing batteries will not delete previous readings.
•The supplied batteries may have a shorter life than new batteries.
•Disposal of used batteries should be carried out in accordance with local regulations.
2.2 Blood Pressure Measurement Tips
To h e l p e n s u r e a n a c c u r a t e r e a d i n g, follow t h ese d ire c t i o n s:
•Stress raises blood pressure. Avoid taking measurements during stressful times.
•Measurements should be taken in a quiet place.
•It is important to take measurements at same times each day. Taking measurements in
the morning and in the evening is recommended.
•Remember to have a record of your blood pressure and pulse readings for your physician.
A single measurement does not provide an accurate indication of your true blood
pressure. Please use the Blood Pressure Diary to keep records of several readings over a
certain period of time. To download PDF files of the diary, visit
www.omron-healthcare.com.
•Avoid bathing, drinking alcohol or caffeine, smoking, exercising and eating for at least
30 minutes before taking a measurement.
•Rest for at least 5 minutes before taking a measurement.

2. Preparation
2.3 Applying the Arm Cuff
•The following steps are for applying the arm cuff to your left arm. When you take a
measurement on your right arm, follow the cuff wrap instructions for a right arm use
mentioned under “To take a measurement on your right arm” located at the end of this
sub-section.
•The blood pressure can differ between the right arm and the left arm, and the measured
blood pressure readings can be different. OMRON recommends to always use the same
arm for measurement. If the readings between both arms differ substantially, check with
your physician to determine as to which arm to use for your measurements.
•Remove tight-fitting or thick clothing from your arm while taking a measurement.
1. Plug the arm cuff into your monitor by inserting the air
plug into the air jack securely.
2. Place your hand through the cuff loop. Pull the cuff
until it reaches your upper left arm.
•The bottom edge of the arm cuff should be 1 to 2 cm
above the inside elbow. The air tube is on the inside
of your arm and aligned with your middle finger.
3. Make sure that the air tube is positioned on the
inside of your arm and wrap the cuff securely, so
it can not move around your arm.
To take a measurement on your right arm
When you take a measurement on your right arm, the
air tube should run along the side of your elbow, along
the bottom of your arm. Be careful not to rest your arm
on the air tube.
2.4 Sitting Correctly
To ta k e a m ea s u re men t , y o u n e ed t o b e r e la x e d a n d
comfortably seated in a room with a comfortable
temperature.
Place your arm on the table.
•Sit in a comfortable chair with your back and arm
supported.
•Keep your feet flat and your legs uncrossed.
• The arm cuff should be placed on your arm at the
same level as your heart, with the arm resting
comfortably on a table.
3.1 Taking a Measurement
• DO NOT use this monitor with other medical electrical (ME) equipment simultaneously.
This may result in incorrect operation and/or cause an inaccurate reading.
•Remain still and do not talk while taking a measurement.
1. Press the [START/STOP] button.
All symbols appear on the display before starting the measurement.
The battery symbol that is displayed at this time do not indicate the battery level. They
are displayed merely for confirmation.
2. Remain still and do not talk until the entire measurement process is
complete.
The “ ” symbol flashes at every heartbeat.
After your monitor has detected your blood pressure and pulse rate, the cuff
automatically deflates. Your blood pressure and pulse rate are displayed.
3. Press the [START/STOP] button to turn your monitor off.
•Wait 2 - 3 minutes between measurements. The wait time allows the arteries to
decompress and return to their pre-measurement state.
You may need t o increase the wait time depending on your individual physiological
characteristics.
■If your systolic pressure is more than 210 mmHg
If your systolic pressure is more than 210 mmHg, take a measurement
manually.
After the arm cuff starts to inflate, press and hold the [START/STOP] button
until the monitor inflates 30 to 40 mmHg higher than your expected systolic
pressure.
Note
•Do not inflate above 299 mmHg.
•Inflating to a higher pressure than necessary may result in bruising of the arm where the
cuff is applied.
