Preparations
Battery installation
1. Remove the cover of the battery slot by
pressing the cover in the direction indicated
by the embossment on the cover.
2. Place 2 AAA batteries in the battery slot as
indicated by the embossment on the bottom
of the battery slot. The negative battery
terminals (-) go against the springs in the
battery slot.
3. Close the cover of the battery slot.
Battery replacement
The device detects the charge level of bat-
teries automatically and indicates a charge
that is too low with a symbol. (battery symbol)
The device retains the measurement memory
for 30 seconds without batteries, so remove
the new batteries from their packaging and
place them next to the device before remov-
ing the old ones.
1. Remove the cover of the battery slot by
pressing the cover in the direction indicated
by the embossment on the cover.
2. Remove the old batteries and replace
them with new ones. Replace both batteries
at the same time.
3. Close the cover of the battery slot.
Note!
• The charge level of batteries decreases in
cool air.
• Old batteries may damage the device, so
when the device indicates a low charge level,
remove the old batteries from the device and
replace them with new ones.
• Do not leave batteries in the device for
more than three months if you do not intend
to use the device.
• Do not mix old and new batteries.
• If you accidentally place the batteries in
the device the wrong way round, remove the
batteries, wait for 1 minute and then place
the batteries in the battery slot again the right
way round.
• Recycle old batteries. They must not be
burned as they may explode.
Recommendations for use
• Always measure blood pressure from the
same wrist and in the same position.
• Measure blood pressure in room tempera-
ture.
• Measure at the same time in the morning,
afternoon and evening. Three times a day.
• During measurement, hold the blood
pressure monitor at heart level so that you are
sitting up straight and supporting your elbow
on a table, for example.
• You should be relaxed during measurement.
30 minutes before measurement, you should
refrain from going to sauna, bathing, exercis-
ing, smoking, eating, alcohol and products
containing caffeine, such as coffee.
• The feeling of needing to urinate raises
blood pressure. Go to the toilet before meas-
urement if you feel the need.
• Calm down and relax for a few minutes
while sitting in place prior to measurement.
• If you take several measurements at a time,
have 5 minute breaks between the measure-
ments.
• The first measurement result is not reliable
because several measurements over a longer
period of time are required to detect the
general level.
• Keep a record of measurement results in the
long term to gain more accurate information
and, if necessary, to present them to your
doctor.
Wrist cuff placement
1. Open the wrist cuff and place it around
the left, bare wrist so that the display of the
device is on the palm side. The palm and the
device are pointed at you.
2. Ensure that the edge of the device is ap-
prox. 1 cm from the bottom of the palm.
3. Wrap the wrist cuff around the wrist with
your right hand and fasten it at the Velcro
tape.
Measuring position
1. Sit in a chair with your back straight and
your feet firmly on the floor.
2. Support your elbow against a table so that
the blood pressure monitor is at heart level.
You can place a pillow under the elbow but
the pillow must not put pressure on the wrist
cuff.
3. Ensure that the palm and the blood pres-
sure monitor are facing you.
4. Let the hand and wrist rest in a relaxed
position.
Taking a measurement
Measurement is started using the On/Off
button and it can be interrupted at any time
using the same button.
1. Press the On/Off button. The display of the
device wakes up and all symbols light up
momentarily on the display.
2. The device flashes the reading “00” a few
times, after which the wrist cuff inflates and
tightens. The reading on the display increases
and reaches its peak.
3. The reading starts to gradually decrease
while the wrist cuff deflates. The device beeps
in time with the pulse while the reading on
the display decreases.
4. When the measurement result is ready, the
device will no longer flash the reading, but
display the systolic pressure, diastolic pressure
and pulse.
5. You can open the wrist cuff and remove the
device from the wrist.
The measurement result is automatically
saved in the device’s memory and the dis-
play/device turns itself off after a short while.
You can also turn off the device using the
On/Off button. It is a good idea to take a 5
minute break before the next measurement.
The second measurement result is often more
accurate.
Warning!
• If the device malfunctions and the wrist cuff
continues to tighten, remove the wrist cuff
and turn off the device immediately.
• Do not use the device if you have injured
your hand. Talk to your doctor first about
using the device.
Viewing saved measurement results
1. Press the Memory button.
The device displays the most recent meas-
urement data. The number in the bottom left
corner of the display indicates the memory
slot (01–99).
2. You can browse the data of previous meas-
urements by pressing the Memory button
again. The device saves 99 measurements,
and when new measurements are taken, the
device deletes the data of the oldest meas-
urements to make way for the new.
The display stays on for 9 seconds and then
turns itself off if the Memory button is not
pressed again, browsing saved measure-
ments. When the display is on, the device can
also be turned off by pressing the Power (On/
Off) button.
Device cleaning and storage
You can wipe the device with a damp cloth
if it is dirty. Place the wrist blood pressure mon-
itor and guide back into their packaging so
that the wrist cuff is rolled up and the display
of the monitor is facing upwards.
Remove the batteries from the battery slot if
you do not intend to use the device for more
than 3 months.
Device calibration
We do not offer recalibration of devices.
