1. Introduction
1.1. Features of the Wrist Blood Pressure Monitor
This blood pressure monitor (with Irregular Heartbeat Detection) is a fully
automatic digital blood pressure measuring device for use on the wrist.
This monitor enables very fast and reliable measurement of your systolic
and diastolic blood pressure as well as pulse by way of the oscillometric
method of measuring. This device offers a very high and clinically tested
measurement accuracy and is designed for maximum user-friendliness.
Before using it please read through this instruction manual carefully and
keep it in a safe place. For further questions on the subject of blood pres-
sure and its measurement please contact your doctor.
Attention!
1.2. Important information about self-measurement
Self-measurement means control not diagnosis or treatment. Your
values must always be discussed with your physician. You should never
alter the dosages of any medication without direction from your
physician. The pulse display is not suitable for checking the functioning of
heart pacemakers!!
In cases of irregular heartbeat, measurements made with this
instrument should only be evaluated after consultation with your
doctor.
Electromagnetic Interference: This device contains sensitive electronic
components. Avoid strong electrical or electromagnetic fields in the direct
vicinity of the device (e.g. mobile telephones microwave ovens etc.). These
can lead to temporary impairment of the monitor’s
measuring accuracy.
2. Important information about blood pressure and its measurement
2.1 How does high/low blood pressure arise?
Your level of blood pressure is determined in the circulatory center of
the brain and adjusts to a variety of situations through feedback from
the nervous system. To adjust blood pressure the strength and
frequency of the heart (Pulse) as well as the width of circulatory blood

4
vessels is altered. Blood vessel width is affected by way of fine muscles in the
blood vessel walls. Your level of arterial blood pressure changes periodically
during heart activity. During the "blood ejection" (Systole) the value is highest
(systolic blood pressure value). At the end of the heart’s "rest period" (Diastole)
pressure is lowest (diastolic blood pressure value). Your blood pressure values
must lie within certain normal ranges in order to prevent particular diseases.
2.2 Which values are normal?
Blood pressure is too high if your diastolic pressure is above 100 mmHg
and/or your systolic blood pressure is over 160 mmHg while at rest. In this
case please consult your physician immediately. Long-term values at this level
endanger your health through continual damage to the blood vessels in you
body. Should your systolic blood pressure values lie between 140 mmHg and
159mmHg and/or your diastolic blood pressure values lie between 90 mmHg
and 99mmHg. Consult your physician. Regular self-checks will be necessary. If
you have blood pressure values that are too low (i.e. systolic values under
105mmHg and/or diastolic values under 60 mmHg) consult your physician.
Even with normal blood pressure values a regular self-check with your blood
pressure monitor is recommended. You can detect possible changes in your
values early and react appropriately. If you are undergoing medical treatment
to control your blood pressure keep a record of values along with time of day
and date. Show these values to your physician. Never use the results of
your measurements to independently alter the drug doses prescribed
by your physician. Which values are normal?
The following standards for assessing high blood pressure (without reagard to
age) have been established by the U.S. National Institutes of Health JNC7 2003.
Category Systolic Diastolic
(mmHg) (mmHg)
Normal <120 and <80
Self-Check
Pre-Hypertension 120 - 139 or 80 - 89
Stage 1 140 - 159 or 90 - 99
Hypertension
Stage 2 ≥160 or ≥100
Hypertension

☞Further information
• If your values are mostly normal under resting conditions but exceptionally
high under conditions of physical or psychological stress it is possible that
your are suffering from so-called "labile hypertension." Consult your physi-
cian.
• Correctly measured diastolic blood pressure values above 120mmHg
require immediate medical treatment.
* This device is not intended for use on children 12 years of age or
younger.
2.3 What can be done if regular high/low values are obtained?
a) Consult your physician.
b) Increased blood pressure values (various forms of hypertension) are
associated with considerable health risks over time. Arterial blood vessels
in your body are endangered due to constrictions caused by deposits in the
vessel walls (Arteriosclerosis). A deficient supply of blood to important
organs (heart brain muscles) can result. Furthermore the heart will
become structurally damaged with increased blood pressure values.
c) There are many different causes of high blood pressure. We differentiate
between the common primary (essential) hypertension and secondary
hypertension. Secondary hypertension can be ascribed to specific organ
malfunctions. Please consult your physician for information about the pos-
sible origins of your own increased blood pressure values.
d)There are measures you can take to reduce and even prevent high
blood pressure. These measures must be permanent lifestyle changes.
1) Eating habits:
•Strive for a normal weight corresponding to your age. See your doctor
for your ideal weight.
• Avoid excessive consumption of common salt.
• Avoid fatty foods.

6
) Previous illnesses
• Consistently follow all medical instructions for treating illness such as:
diabetes (diabetes mellitus or sugar diabetes) fat metabolism disorder
and gout.
3) Habits
• Give up smoking completely.
• Drink only moderate amounts of alcohol.
• Restrict your caffeine consumption (coffee tea and chocolate).
4) Your physical condition
• After a medical examination and with your doctor’s approval and
direction; exercise.
• Choose sports which require stamina and avoid those which require
strength.
• Avoid reaching the limit of your performance.
• With previous illnesses and/or an age of over 40 years please
consult your physician before beginning your exercise routine. You
must receive advice regarding the type and extent of exercise that is
appropriate for you.
2.4 Irregular Heartbeat Detection
The appearance of the symbol signifies that a certain irregular
heartbeat was detected which could cause cardiovascular disease. This
indicator is only a caution. This blood pressure monitor can detect blood
pressure and pulse rate measurement with specifications even if the
patient is having an irregular heartbeat interval. It is important that you
be relaxed remain still and do not talk during measurements.
Note: We recommend contacting your physician if you see this
icon frequently.
CAUTION: An irregular heartbeat can be a serious medical condition
requiring medical attention. See your doctor if you have an irregular
heartbeat.

4. Using your Blood Pressure Monitor for the First Time
4.1. Activate the Pre-Installed Batteries
Pull out the protective strip protruding from the battery compartment.
4.2 Setting the date and time
1. After the new batteries are activated the year num-
ber flashes in the display. You can advance the year
by pressing the "M" button. To confirm and then set
the month press the time button.
2. You can now set the month using the “M” button. To
confirm and then set the day press the time button.
3. Please follow the instructions above to set the day
hour and minutes.
4. Once you have set the last minute and pressed the
time button the date and time are set and the time
is displayed.
5. If you want to change the date and time press and
hold the time button down for approx. 3 seconds
until the year number starts to flash. Now you can
enter the new values as described above.
5. Taking a Blood Pressure Measurement
5.1. Before the measurement:
• Avoid eating smoking as well as all forms of exertion directly before
your measurement. These factors influence the measurement result.
Relax by sitting in an armchair in a quiet atmosphere for about ten
minutes before your measurement.
• Always measure on the same wrist (normally left).
• Compare readings at the same time of day since your blood pressure
changes during the course of the day.

5.2. Common sources of error:
Note:
Comparable blood pressure measurements always require the same
conditions! These are normally always quiet conditions.
• All efforts by the patient to support the arm can increase blood pres-
sure. Make sure you are in a comfortable relaxed position and do not
activate any of the muscles in the measurement arm during the mea-
surement. Use a cushion for support if necessary.
• If the wrist artery lies considerably lower (higher) than the heart an
erroneously higher (lower) blood pressure will be measured! (Each
15cm/6" difference in height results in a measurement error
of10mmHg!)
• A loose cuff causes false measurement values.
• With repeated measurements blood can accumulate in the respective
arm which can lead to false results. Correctly executed blood pressure
measurements should therefore first be repeated after a 1 minute
pause or after the arm has been held up in order to allow the accumu-
lated blood to flow away.
5.3. Fitting the cuff
a) Remove all objects and jewelry (e.g.
wristwatch) from the wrist in use. Put the
cuff over the wrist with the monitor face
on the inside of the wrist.
b) The distance between the cuff and the
hand should be approx. 10 mm (1/2").
c) Secure the cuff with the Velcro fastener
so that it lies comfortably and not too
tight. No space should remain between
the cuff and the wrist.
9

d)Lay your arm on a table with the palm
upwards.
Support the arm a little with a cushion so that the
cuff rests at about the same height as the heart.
Remain still for 2 minutes before beginning the
measurement.
5.4. Measuring procedure
After the cuff has been appropriately positioned the measurement can
begin:
a) Press the ON/OFF button to begin. After
pressing the ON/OFF button the pump
begins to inflate the cuff. In the display
the increasing cuff-pressure is continually
displayed.
b) After reaching the inflation pressure the
pump stops and the pressure slowly falls.
The cuff pressure (large characters) is dis-
played during the measurement. When
the device has detected the pulse the
heart symbol in the display begins to
blink and a beep tone is audible for every
pulse beat.
c) When the measurement has been concluded a long beep tone sounds.
The measured systolic and diastolic blood pressure values as well as
the frequency are now displayed.
(Pulse=number of heartbeats each minute)
Example (Fig.): Systolic 118 Diastolic 73
Pulse 75. The measurement results are dis-
played until you switch the device off.

If no button is pressed for 5 minutes the device switches off automati-
cally to save the batteries.
5.5. Discontinuing a measurement
If it is necessary to interrupt a blood pressure measurement for any
reason (e.g. the patient feels unwell) the ON/OFF button can be
pressed at any time. The device then immediately lowers the cuff pres-
sure automatically and enters into sleep mode.
5.6. Irregular Heartbeat Detection
This symbol indicates that certain pulse irregulari-
ties were detected during the measurement. In this case the
result may deviate from your normal basal blood pressure –
repeat the measurement. In most cases this is no cause for
concern. However if the symbol appears on a regular basis
(e.g. several times a week with measurements taken daily)
we advise you to tell your doctor. Please show your doctor
the following explanation:
Information for the doctor on frequent appearance of the Irregular Heart-
beat Symbol
This instrument is an oscillometric blood pressure monitor device that also
analyzes pulse frequency during measurement. The instrument is clinically
tested.
If pulse irregularities occur during measurement the irregular heartbeat sym-
bol is displayed after the measurement. If the symbol appears more frequently
(e.g. several times per week on measurements performed daily) or if it sudden-
ly appears more often than usual we recommend the patient to seek medical
advice.
The instrument does not replace a cardiac examination but serves to detect
pulse irregularities at an early stage. 11

5.7. Hypertension Risk Indicator
The colored bars on the left-hand edge of the LCD show you the range within
which the indicated blood pressure value lies. Depending on the color of the
bar the readout value is either within the normal (green) borderline (yellow) or
danger (orange red) range.
The classification is based on standards established by the National Institutes
of Health JNC7 2003. Refer to the chart in section 2.2 of this instruction man-
ual for details of the classifications.
The traffic light bar illuminates according to your measurement:
• If the green bar lights up your measurement is “Normal” according to NIH
standards.
• If the yellow bar lights up it is “Pre-Hypertension” according to NIH stan-
dards.
• If the orange bar lights up it is in the “Stage 1 Hypertension” zone.
• If the red bar lights up it is in the “Stage 2 Hypertension” zone.
5.8. Memory storage and recall of the measurements
This blood pressure monitor automatically stores the last 99 measure-
ments values for each user. By pressing the MEMORY button average of
existing memory readings displayed first with an “A” and (MR) at the
lower left. Press MEMORY button again the last measurement (MR99) as
well as the previous 98 measurements (MR98 MR97 …..MR1) can be
displayed one after the other.
5.9.Memory cancellation of all measurements
Attention!
Before proceeding to clear all the memory make sure that you don’t have
to make reference to the readings in the future.
To delete all stored readings press the MEMORY
button for at least 7 seconds. The display will show
the symbol "CL" and 3 short beeps will sound to
indicate deletion of stored readings.

puter and device is successfully made. As long as the cable is plugged
the bars will keep flashing and the buttons are disabled.
During the connection the device is completely controlled by the
computer. Please refer to the ‘help’ file in the software for detailed
instructions or call 1-800-568-4147.
7. Setting the Medication Reminder
This instrument allows you to set two alarm times at which an alarm signal
will then be triggered. This can be a useful aid for instance as a reminder to
take medication or to remind you to take your blood pressure at the same time
each day.
1. To set an alarm time press the time button (the instru-
ment must have been switched off beforehand) and
13
• Windows XP, Vista, 7

8. Battery Charge Indicator
Batteries almost discharged
When the batteries are approximately 75% used the battery
symbol will flash as soon as the instrument is switched on (if at
least one of the batteries still has some charge). Although the
instrument will continue to measure reliably you should obtain
replacement batteries.
Batteries discharged replacements required
When the batteries are discharged the battery symbol will flash as soon
as the instrument is switched on. You cannot take any further measure-
ments and must replace the batteries.
1. Open the battery compartment at the back of the instrument.
2. Replace the batteries – ensure they are inserted correctly as shown on
the symbols in the compartment.
3. The memory retains all values although date and time must be reset -
the year number will flash automatically after batteries are replaced.
4. To set date and time follow the procedure described in Section 4.2.
Which batteries and which procedure?
Use two new longlife 1.5V AAA batteries. Do not use batteries beyond
their expiration date. If the monitor is not going to be used for a pro-
longed period the batteries should be removed.
Using rechargeable batteries
You can also operate this instrument using rechargeable batteries.
• Please use only type "NiMH" reusable batteries!
• If the battery symbol ( ) appears the batteries must be removed and
recharged! They must not remain inside the instrument as they may become
damaged through total discharge even when switched off. The batteries must
NOT be discharged in the blood pressure monitor! If you do not intend to use
the instrument for a week or more always remove the rechargeable batteries!
• Recharge these batteries using an external charger and follow manu-
facturer’s instructions carefully. 15

9. Error messages/Troubleshooting
If an error occurs during a measurement the measurement is dis-
continued and a corresponding error code is displayed (Example:
Error No. 2).
Error No. Possible cause(s)
ERR 1 No pulse was detected. Ensure the cuff is properly placed on
the inside of you wrist and repeat a measurement
ERR 2 Unnatural pressure impulses influenced the measurement
result. Reason: The arm was moved during the Measurement
(Artefact). Repeat keeping still and quiet.
ERR 3 Inflation of the cuff takes too long. The cuff is not correctly
seated. Re-position cuff and repeat
ERR 5 The measured readings indicated an unacceptable difference
between systolic and diastolic pressures. Take another read-
ing following directions carefully. Contact your
doctor if you continue to get unusual readings.
HI The cuff pressure is too high. Relax for 5 minutes and
repeat the measurement.*
LO The pulse is too low (less than 40). Repeat the measure-
ment.*
* If this or any other problem occurs repeatedly, please consult
your doctor.

Other possible malfunctions and their remedies
If problems occur when using the device the following points should be
checked and if necessary the corresponding measures are to be taken:
Malfunction
The display remains
blank when the instru-
ment is switched on.
The device frequently
fails to measure blood
pressure values or the
values measured are too
low (too high).
Every measurement pro-
duces a different value.
Blood pressure values
measured at your doctors
office differ from your
measurements.
17
Remedy
1. Check batteries for correct polarity.
2. If the display is unusual re-insert batter-
ies or exchange them.
1. Check the positioning of the cuff.
2. Measure blood pressure again in peace
and quiet carefully following the details
in Section 5.
1.Please read the following information
listed in Section 5.2
"Common sources
of error ." Repeat the measurement.
Please note: Blood pressure fluctuates
continually so successive measure-
ments will show some variability.
1.Record the daily development of the
measured values and consult your doctor.
Please note: Individuals visiting their
doctor frequently experience anxiety
which can result in a higher reading
than at home under resting conditions
.

18
10. Care and maintenance
a) Do not expose the device to either extreme tem-
peratures humidity dust or direct sunlight.
b) The cuff contains a sensitive air-tight bubble. Han-
dle this carefully and avoid all types of straining
through twisting or buckling.
c) Clean the device with a soft dry cloth. Do not use
gasoline thinners or similar solvents. Spots on the
cuff can be removed carefully with a damp cloth
and soapsuds. The cuff must not be washed!
d) Do not drop the instrument or treat it roughly in
any way. Avoid strong vibrations.
e) Never open the device! Otherwise the manufac-
turers warranty becomes invalid!
Further information
Blood pressure is subject to fluctuations even in healthy
people.
Comparable measurements always require the same conditions
(quiet conditions)!
If fluctuations in readings are larger than 15mmHg, and/or you hear
irregular pulse tones, consult your doctor.
In order to receive market clearance from governmental bodies this device
was subjected to strict clinical tests. The computer program used to measure
blood pressure values was tested by experienced cardiac specialists in Ger-
many.
Never attempt to repair the instrument yourself!
Any unauthorized opening of the instrument invalidates all warranty claims!
Periodical accuracy check
Sensitive measuring devices must from time to time be checked for accu-
racy. We therefore recommend a periodical inspection of the static pres-
Gasoline
