Information You Should Know Before
Operating the Unit
Caution
1. Consult your physician to verify your blood pres-
sure range before measuring it at home with this
unit.
2. If the cuff causes any discomfort during
measurement, press the START button to turn
off the unit immediately.
3. If the pressure is over 300mmHg and the cuff
does not deflate automatically, pull off the Vel-
cro strap to detach the arm cuff.
Blood pressure measurements obtained with this
unit are equivalent to those obtained by a trained
person using the cuff/stethoscope auscultation
method.
WARRANTY:
Three years from the date of purchase.
What is blood pressure?
A force is created by the heart as the ventricle
forcibly ejects blood into the blood vessels and
through the vascular system. Another force is cre-
ated by the arteries as they resist the blood flow.
Blood pressure is the result of these two forces.
What are systolic and diastolic blood
pressures?
Systolic blood pressure is the highest pressure at
the heart‘s maximum contraction. Diastolic blood
pressure is the lowest pressure when the heart is
resting.

Comparison to WHO recommendations
See the following blood pressure classification
chart released by the WHO (World Health Organi-
zation) for evaluation of your blood pressure level.

What about low blood pressure?
In general, a lower blood pressure reading is
better unless it causes unpleasant symptoms such
as fainting and/or lightheadedness.
Fluctuation and variation in blood pressure
The following chart shows possible blood pressure
fluctuations during a 24-hour period.
The following factors will influence blood pressure
measurement results and cause variations.
• Bathing
• Conversation
• Drinking alcohol
• Exercise
• Moving
• Mental tension
• Eating
• Temperature changes
• Thinking
• Smoking etc.
• Breathing

The Geratherm desktop 2.0 has a combination of
2 measuring methods in one measuring procedure
– the so-called „Double Check Technology“ (DCT).
This intelligent measuring method measures the
blood pressure values during inflation and defla-
tion and guarantees excellent measuring results
and highest accuracy.

For rapid measuring results you can switch to the
established „fuzzy logic“ mode (measurement du-
ring release of pressure only).
The blood pressure monitor provides a USB con-
nector plus analysis software, enabling easy trans-
fer to the computer and evaluation of the blood
pressure values.
Furthermore Geratherm desktop 2.0 has arrhyth-
mia detection (pulse arrhythmia detection), 50
memory locations for 2 persons, WHO classifica-
tion (classification of blood pressure values as per
World Health Organisation standards) and back-
light of display.

Installing/Replacing Batteries
1. Insert the batteries into the battery compartment
matching correct polarities “+” and “-”.
2. Replace all batteries if the low battery indicator
appears.
3. Remove the batteries if the unit will not be used
for a long period of time.
Note:
It is recommended that the same type of alkaline
batteries be used to avoid incompatibility.
Please dispose of defective appliances and used
batteries in compliance with statutory regulations
(disposal in general household waste is prohibi-
ted!).
Preparation for Use
4 type „AA“
batteries

GB
31
Preparation for Use
Attaching the Pressure Cuff
1. Wrap the cuff around the left arm. The arm
should be bare.
2. Fasten the cuff. Don’t pull it too strongly or
make the cuff too tight. The edge of the cuff
should be approximately 1 inch from the crease
of your elbow.
3. Attach the cuff on the right arm as shown in the
figure if it is not possible to measure on the left
arm.

GB
32
Measuring Posture
1. Sit upright and ensure that the cuff is at heart
level. Relax and retain a natural posture during
measurement.
2. Measure and
record blood
pressure at the
same time every
day to establish
your blood pres-
sure pattern.
AC Adapter
It is possible to use a stabilized AC adapter (output
6 V DC/800 mA) to operate the device.
Note:
1. No power is taken from the batteries while the
AC adapter is connected to the device.
2. If AC adapter power is interrupted during mea-
surement, the device must be reset by discon-
necting the AC adapter from the device.
3. Please use only the power adapter supplied by
Geratherm. Using commercially available pow-
er adapters may damage your blood pressure
gauge.
Power source

Operations
Setting the Clock and Date
With the unit switched off, press the MEMORY but-
ton until the display shows a blinking year.
Press the START button to adjust the year while
it is blinking.
Then press the MEMORY button again; the month
will appear and blink. Adjust the month using the
START button.
Repeat these operations for entering date, hour
and minute.
Measuring Blood Pressure
You may choose between 2 measuring modes:
fuzzy logic (measurement during deflation) and
Double Check Technology (measurement during
inflation and deflation). Select prefered measuring
mode using the buttons on the side of the unit.
Press the MEMORY GROUP button to choose
the desired memory group where you would like
to store the measuring values (the default setting
is memory group number 1).
fuzzy logic Double Check Technology

GB
34
You may also select or change the memory group
by pressing the button after measurement (values
are shown on the display).
Press START to start measuring.
When the measurement is completed, the display
will show the measured blood pressure values,
pulse rate, memory group, date/time and WHO
color classification.
Press START to turn off the unit. Otherwise it will
turn off automaitcally after about 150 seconds.
As regards the WHO classification, please read on
page 26.
Note:
If the symbol “ ” appears, it means the unit
has detected irregular pulse during measurement.
If the symbol appears regularly please consult a
qualified physician for professional advice.
