Intended use of Braun ExactFit™ 2
This device is intended for home use, to intermittently measure systolic and
diastolic blood pressure and pulse rate in adults.
This device has not been tested for and hence is not intended for neonatal and
infant subjects, pregnant, including pre-eclamptic users.
This blood pressure monitor is not intended for clinical use in a professional
environment and is for home usage only. The use of this blood pressure
monitor is not intended as a substitute for a consultation with your doctor.
What you should know about blood pressure
Blood pressure constantly changes throughout the day. It rises sharply in the early
morning and declines during the late morning. Blood pressure rises again in the
afternoon and nally drops to a low level at night. Also, it may vary in a short
period of time. Therefore, readings from successive measurements can uctuate.
This device will display your blood pressure reading referring to two values:
systolic and diastolic, through the principle of pressure oscillation. The systolic
blood pressure (the upper number) indicates how much pressure your blood is
exerting against your artery walls when the heart beats. The diastolic blood
pressure (the lower number) indicates how much pressure your blood is exerting
against your artery walls while the heart is resting between beats. The pulse
value is also displayed after each measurement.
Blood pressure measured in a doctor’s oce only provides a momentary value.
Repeated measurements at home better reect one’s actual blood pressure
values under everyday conditions.
Regular blood pressure measurements taken at home can provide your doctor
with valuable information on your normal blood pressure values under actual
«everyday» conditions.
*LCD display text and icons ash for Hypertensive Crisis reading
If you are under medical treatment or taking any medication, please consult
your doctor rst. DO NOT adjust medication based on measurement results
from this blood pressure monitor. Take medication as prescribed by your
doctor. Only a doctor is qualied to diagnose and treat high blood pressure.

Safety information and important
precautions
To ensure accurate measuring results, read the complete instructions for use carefully.
People suering from renal diseases, cardiac arrhythmia, vascular constriction,
arteriosclerosis in the extremities, diabetes or users of cardiac pacemakers
should consult their doctor before measuring their blood pressure themselves.
Deviations in blood pressure values may occur in such cases.
If your blood pressure reading is in the hypertensive crisis range with a systolic
blood pressure value higher than 180 mmHg and / or a diastolic blood
pressure value higher than 120 mmHg and you nd you have one or two
readings in this range - please see your doctor immediately.
The use of this blood pressure monitor is not intended as a substitute for a
consultation with your doctor.
Avoid compression or restriction of the connection tubing. Continuous cu
pressure due to the connection tubing kinking can aect blood ow and cause
possible injury to the user.
DO NOT use this device on the arm of the same side of the body on which the
user had a mastectomy. Measuring blood pressure too frequently can cause
injury to the user due to blood ow interference.
DO NOT apply the cu to a limb on which there is intravascular access or on
which an arterio-venous (A-V) shunt is present. This can cause temporary
interference of blood ow and potential injury to the user.
DO NOT apply the cu over a wound as this can cause further injury.
DO NOT use the device while simultaneously using other medical electrical
(ME) equipment.
DO NOT use this device on neonates or infants, pregnant people, or persons
who cannot express their intentions.
Inserting batteries
• Use alkaline batteries, type AA 1.5V
as supplied with this product.
• Remove the battery compartment cover and
insert four batteries with correct polarity (see
symbol in the battery compartment).
Only discard empty batteries. They
should not be disposed of in the
household waste, but at appropriate
collection sites or at your retailer.
Key rules for accurate blood pressure measurement
ALWAYS take readings at the same time of day, under the same conditions.
DO NOT take a measurement within 30 minutes of smoking, drinking coee or
tea or any form of exertion. These factors will inuence the measurement.
ALWAYS measure on the same arm. The left arm is recommended. DO NOT
move or speak while measurement is being taken. Keep your legs uncrossed
and feet at on the oor.
Place the cu in direct contact with the skin. DO NOT wrap the cu over a
jacket, sweater or shirt.
If you want to take multiple measurements, wait approximately 3 minutes
before repeating a measurement.

Applying the arm cuff
1. Plug the air hose into the connector (Fig. 1).
2. The cu is located correctly when the velcro is on the outside of the cu
and the metal ring does not touch the skin (Fig. 2).
3. Put your arm through the cu loop. The bottom of the cu should be
approximately 0.8” - 1.2” (2~3 cm) above elbow (Fig. 3). The tube should lie
over the brachial artery on the inside of the arm (Fig. 4).
4. Pull the cu so that the top and bottom edges are tightened around your
arm, make sure not to wrap the cu very tightly. Allow space for one nger
to t between the cu and the arm.
5. When the cu is positioned properly, press the velcro rmly against the
pile side of the cu.
6. This cu is ready for use if the arrow heads fall within the range on the
other side of the cu when the cu is tightened around your arm (Fig. 5).
7. Sit on a chair and place your arm on the table so that the cu is at the same
level as your heart (Fig. 6).
Taking a measurement
8. Sit down with straight back with your feet at
on the oor.
9. Ensure the cu is wrapped snugly (per the
“Applying the arm cu” section above, Fig. 3-6).
10. Do not move the unit during measurement, or
the proper measurement will not be achieved.
11. Press power button
to begin. The last results will be shown on the
screen (M reading). The measurement starts automatically. While
measurement is in progress, do not move or speak. Note: If necessary to
interrupt a measurement, press the power button
at any time. The
device immediately cancels the measurement, lowers cu pressure
and automatically turns o.
12. The cu will rst inate and then deate. At the end of the measurement
the reading is displayed:

Irregular heartbeat detector
Talking, moving, shaking or an irregular pulse during the measurement can
result in the appearance of this icon. Usually this is not a cause for concern,
however if the symbol appears often, we recommend you seek medical advice.
The device does not replace a cardiac examination, but it could help
identifying pulse irregularities to be discussed with your doctor.
The symbol at the left-hand side of pulse reading indicates
heartbeat during measurement.
This symbol at the left-hand side of pulse reading indicates that pulse
irregularities were detected after the measurement. This irregular
heartbeat can be caused simply by talking, moving or shaking during a
measurement. In this case, the result may deviate from your normal
blood pressure – repeat the measurement. Normally this is not cause
for concern. However if the symbol appears frequently, and these
guidelines are strictly followed, seek medical advice.
