Thank you for purchasing the OMRON RS6 Wrist Blood Pressure 
Monitor.

The OMRON RS6 is a compact and easy to use blood pressure 
monitor, operating on the oscillometric principle. It measures your 
blood pressure and pulse rate simply and quickly. For comfortable 
controlled inflation without the need of pressure pre-setting or 
re-inflation the device uses its advanced “IntelliSense” technology.

Intended Use
This product is designed to measure the blood pressure and pulse 
rate of people within the range of the designated wrist cuff, following 
the instructions in this instruction manual.
It is mainly designed for general household use. Please read the 
Important Safety Information in this instruction manual before using 
the unit.

Please read this instruction manual thoroughly before using the 
unit.
Please keep for future reference.
For specific information about your own blood pressure, 
CONSULT YOUR DOCTOR.

Consult your doctor prior to using in pregnancy or if diagnosed with 
arrhythmia or arteriosclerosis.
Please read this section carefully before using the unit.

Warning:

• Indicates a potentially hazardous situation which, if not avoided, 

could result in death or serious injury.

(General Usage)

• Always consult your doctor. Self-diagnosis of measurement results 

and self-treatment are dangerous.

• People with severe blood flow problems, or blood disorders, should 

consult a doctor before using the unit, as cuff inflation can cause 
internal bleeding.

(Battery Usage)

• If battery fluid should get in your eyes, immediately rinse with 

plenty of clean water. Consult a doctor immediately.

Caution: 

• Indicates a potentially hazardous situation which, if not avoided, 

may result in minor or moderate injury to the user or patient or 
damage to the equipment or other property.

(General Usage)

• Do not leave the unit unattended with infants or persons who 

cannot express their consent.

• Do not use the unit for any purpose other than measuring blood 

pressure.

• Do not use a mobile phone or other devices that emit 

electromagnetic fields, near the unit. This may result in incorrect 
operation of the unit.

• Do not disassemble the unit or wrist cuff.
• Do not operate the unit in a moving vehicle (car, airplane).

(Battery Usage)

• If battery fluid should get on your skin or clothing, immediately rinse 

with plenty of clean water.

• Use only two “AAA” alkaline (LR03) batteries with this unit. Do not 

use other types of batteries.

• Do not insert the batteries with their polarities incorrectly aligned.
• Replace old batteries with new ones immediately. Replace both 

batteries at the same time.

• Remove the batteries if the unit will not be used for three months or 

more.

• Do not use new and used batteries together.

General Precautions

• Do not apply strong shocks and vibrations to or drop the unit.
• Do not take measurements after bathing, drinking alcohol or 

caffeine, smoking, exercising or eating.

• Do not inflate the wrist cuff when it is not wrapped around your 

wrist.

• Read and follow the “Important information regarding Electro 

Magnetic Compatibility (EMC)” in the Technical Data Section.

• Read and follow the “Correct Disposal of This Product” in the 

Technical Data Section when disposing of the device and any used 
accessories or optional parts.

Display:

2.1 Installing/Replacing the Batteries

• If the battery low symbol (

) appears on the display, turn off 

the unit then replace both batteries at the same time.

• The measurement values continue to be stored in memory 

even after the batteries are replaced.

Disposal of used batteries should be carried out in accordance 
with the national regulations for the disposal of batteries.

2.2 Setting the Date and Time

Notes:
• If the batteries have been removed, the date and time setting 

will need to be reset.

• If the date and time are not set, “-:--” appears during or after 

measurement.

3.1 Applying the Wrist Cuff

Do not apply over clothing.

3.2 How to Sit Correctly

• Relax your wrist and hand. Do not bend your wrist back, clench 

your fist, or bend your wrist forward.

3.3 Taking a Reading

Notes:
• To cancel a measurement, press the START/STOP button at 

any time during measurement.

• Remain still while taking a measurement.

After the Positioning symbol lights for more than 2 seconds, 
the wrist cuff will start to inflate automatically.

Cuff Wrapping Guide

The Cuff Wrapping Guide is a unique feature that 
indicates if the cuff is not wrapped tightly enough 
around the wrist. Even when the

 

 

is displayed, a 

blood pressure reading will be taken.

Note: This reading is 

NOT

 reliable due to the incorrect 

wrapping of the cuff. Please wrap the cuff again, taking 
care to wrap it correctly and take the measurement 
again. When the 

 is displayed, the cuff is correctly 

wrapped tightly enough on the wrist and the reading is 
accurate and reliable.

The monitor automatically stores the measurement in its memory.
It will automatically turn off after two minutes.

This criteria is for home blood pressure measurement.

If the irregular heartbeats cause the measurement to be 
invalid, no result is shown. If the irregular heartbeat symbol 
(

) is shown after you have taken a measurement, repeat 

the measurement. If the irregular heartbeat symbol (

) is 

shown frequently, please make your doctor aware of it.

• The blood pressure can differ between the right arm and the 

left arm, and therefore also the measured blood pressure 
values can be different. OMRON recommends to always use 
the same arm for measurement. If the values between the 
two arms differ substantially, please check with your 
physician which arm to use for your measurement.

 Warning:

Self-diagnosis of measured results and treatment are 
dangerous. Please follow the instructions of your doctor.

1) Push the 

 button to change.

• Hold down to advance the digit 

rapidly.

2) Push the 

 button to confirm.

• Next setting appears.

1.

Put your arm through the 

cuff loop.

Your palm should face upward.

 

2.

Wrap the wrist cuff around 

your wrist.

Wrap the wrist cuff securely 
around the wrist for taking 
accurate measurements.

 

Make sure that the wrist cuff 
does not cover the protruding 
part of the wrist bone (ulna) on 
the outside of the wrist.

Notes:
• You can take a measurement on 

either your left or right wrist.

• If the wrist cuff comes off, 

assemble as shown in the figure.

 

 

To take a measurement, you need 
to be relaxed and comfortably 
seated, under comfortable room 
temperature. No bathing, drinking 
alcohol or caffeine, smoking, 
exercising or eating 30 minutes 
before taking a measurement.

• Sit on a chair with your feet flat on the 

floor.

• Sit upright with your back straight.
• The cuff should be at the same level 

as your heart.

 

1.

Press the START/STOP button.

All the symbols appear on the display.
While your position is improper, the Positioning symbol and the 
Positioning indicator flash, when you are in proper position the 
Positioning symbol lights on the display.

The monitor is in 
proper position.

The monitor is higher 
than the heart.

The monitor is lower 
than the heart.

3.

Press the START/STOP button to turn off the monitor.

Important:

• Recent research suggests that the 

following values can be used as a 
guide to high blood pressure for 
measurements taken at home.

Systolic Blood Pressure

Above 135 mmHg

Diastolic Blood Pressure

Above 85 mmHg

• Your blood pressure monitor includes an 

irregular heartbeat feature. Irregular 
heartbeats can influence the results of the 
measurement. The irregular heartbeat 
algorithm automatically determines if the 
measurement is usable or needs to be 
repeated. If the measurement results are 
affected by irregular heartbeats but the result 
is valid, the result is shown together with the 
irregular heartbeat symbol (

). 

• If you move during measurement,  the 

movement error symbol (

) will appear on the 

display. Keep still and repeat the measurement.

Notes:
• Wait 2 - 3 minutes before taking another 

blood pressure measurement. Waiting 
between readings allows the arteries to 
return to the condition prior to taking the 
blood pressure measurement.

1.

Press and hold the 

 

button to reset the 
Positioning sensor.
The Positioning sensor 
is set "on" as default.

 

2.

Press the START/STOP button to store the setting.
