GENERAL REMARKS• Be sure that the cuff size is appropriate to your arm circumference before attaching
the cuff. Refer to the “SPECIFICATIONS” for the size.
• If you feel urinate, do so before measuring your blood pressure.
• Take five or six deep breaths and then relax before measuring your blood pressure. If
you are tense when taking measurement, you will not get a correct reading.
• Your blood pressure will be elevated if you are anxious or irritated, suffering from lackof sleep or constipation, or have just taken some exercise or eaten a meal.
• Do not measure your blood pressure after smoking, bathing or drinking alcohol, coffee
or tea.
• Measure your blood pressure where the room temperature is around 68°F/20°C. Do
not measure your blood pressure when it is below 50°F/10°C or above 104°F/40°C inthe room.
• Measure your blood pressure when you are relaxed and still. Keep the cuff at theheight of your heart and do not move your arm and talk.
• Analyzing blood pressure data gathered over a long period is more important thanjust checking one measurement. Choose the time of day that you are most likely to beable to maintain taking measurements and try to measure your blood pressure at thesame time every day.

NAMES OF PARTS– USING BATTERIES –1 Press the “START/STOP” button to start measurement.

1 Remove the battery cover.

All digits are displayed. Then the cuff begins pressurizing automatically.

Place a finger on the hook, and pull the cover toward you to open.

2 Insert the batteries.
Be sure to insert the batteries into the negative side with the protruding springs
first so as not to mix up the positive and negative terminals.

3 Close the battery cover.
Fit the lugs into the recesses and close the battery cover until you hear a click.
* When the battery icon or is displayed, or nothing appears in the display, replace
all 4 batteries with new ones at once.
* Do not use any other kind of battery other than that alkaline, manganese, and do not
mix them up.
* The memory is erased if the batteries are removed for replacement. It is recommended
to make note of the data stored in memory prior to changing batteries.
* Dispose of used batteries properly according to the rules of your local municipality.

ATTACH THE CUFF
1 Insert the air hose plug into the main unit.
* Do not bend the air hose during measurement,
which may cause inflation error or harmful
injury due to continuous cuff pressure.

2 Attach the cuff.
Unroll the cuff and put the end of the cuff
through the metal loop so that the side with the
Air hose plug
hook and loop fastener is on the outside.
* Be sure that the cuff size is appropriate to your arm circumference before attaching
the cuff.
* Attach the cuff over a bare arm or a thin sleeve.
* If you roll up your sleeve, your upper arm will be constricted and this affects yourresult.
* The blood pressure value is likely to differ between the right arm and left arm.
Measure your blood pressure with the same arm each day.

(1) Attach the cuff around your arm so that the blue marker comes to the palm side
and center of your arm. Adjust the position where the hem of the cuff is 0.4” 0.8”/ 1 cm - 2 cm above your elbow.
(2) Pull the end of the cuff outwards so that the cuff is snug around your arm andthen secure it with the hook and loop fastener. The appropriate tightness of
attaching cuff is that if you can readily slide a finger between the cuff and your
arm.

Be sure to read the following instructions before using the device.

Consult your physician before using the device if you have following conditions suchas heart disease, cardiovascular disease, common arrhythmias, such as atrial or
ventricular premature beats or atrial fibrillation, arterial sclerosis, poor perfusion,
diabetes, pregnancy, preeclampsia, renal disease, weak pulse, experiencing
mastectomy, other blood circulatory diseases, or if you use a cardiac pacemaker.
Do not use measurement results for self-diagnosis and self-treatment. Always consult
your physician.
If the battery fluid gets in your eyes or on your skin, rinse it off with water immediately
and then receive treatment from your physician.
Do not use the device on the injured arm or the arm under medical treatment.
Do not attach the cuff on the arm while on an intravenous drip or blood transfusion.
Do not share the cuff with other infective person to avoid cross-infection.
Do not use the device in the vicinity of flammable gases such as those used foranesthesia. It could ignite the gases and cause an explosion.
Do not use the device in enriched oxygen environments such as a hospital's
hyperbaric chamber or oxygen tent. It could ignite the oxygen and cause a fire.
The air hose of the cuff may cause accidental strangulation in infants.
CautionIf you find any serious incident that has occurred in relation to the device,please report to the manufacturer and the competent authority of the Member
State.

Thank you very much for purchasing
CITIZEN product. This device is a noninvasive blood pressure monitor by
oscillometric method and is intended to
be used for home use. It can measure thesystolic blood pressure (SYS), the diastolicblood pressure (DIA) and the pulse rate.

Do not use the device for any purpose other than measuring blood pressure.
Do not attempt to disassemble, repair or modify the device or the cuff.
Do not use the device for infants or persons who cannot express their intentions.
Do not measure your blood pressure consecutively or frequently. It causes blood
congestion and you will not get a correct reading. Wait at least a few minutes before
measuring again.
If you feel there is something abnormal with your body or you start to feel unwellduring measurement, discontinue use and consult your physician.
If the irregular heartbeat indicator appears frequently, consult your physician about
your health.
Press the “START/STOP” button to reduce the pressure immediately or remove the cuff
if it does not start deflating during the measurement.
Do not use device near a mobile phone, other devices that emit electromagnetic
fields or in high electromagnetic environment. This could cause malfunction.

The [BPM] is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the [BPM] can help prevent
