4. Prepare measurement

Inserting battery

•  Remove the battery cover from the 

back of the monitor.

•  Insert four AA 1.5 V alkaline 

batteries. Making absolutely 
sure that you insert them with 
the  correct  polarity as marked. 
Never use rechargeable bat teries. 

•  Replace the battery cover carefully.

If 4 warning tones have been sounded and the symbol 

 

appears simultaneously on the display, it is no longer possible 
to perform a measurement and all batteries must be replaced. 
Once the batteries have been removed from the device, the 
time must be set again. Used batteries should not be disposed 
of in normal household waste. Dispose of them via your elec-
tronics retailer or your local recycling point.
You are legally obligated to do so. 

Note: Batteries containing pollutant substances 
are marked as follows: Pb = Battery contains lead, 
Cd = Battery contains cadmium, Hg = Battery 
contains mercury. 

Setting date and time

You should set the date and time without fail. Otherwise, you 
will not be able to save your measured values correctly with 
a date and time and to access them again later. The time is 
shown in 12-hour format i.e. the time from 13:00 is displayed 
as 01:00 PM. 
Proceed as follows to set the date and time: 
• Confirm twice using the SET button.
• Use the + or - buttons to first set the month 1–12, and then 

confirm using the SET button.

• Set the day/hour/minute and confirm each using the SET 

button.

Press the button   to exit the settings mode.

5.  Measuring blood 

pressure

Positioning cuff 

Fit the cuff round your bare left up-
per arm. Blood circulation in the 
arm should not be restricted by  tight 
clothing or other objects. 
The cuff should be placed on the 
upper arm so that the lower edge is 2 
to 3 cm above the bend of the elbow 
and above the artery. The tube should 
be in line with the centre of the palm. 
Now place the free end of the cuff 
snugly, but not too tightly, around 
the arm, and fix it with the Velcro fas-

4 x AA (LR06) 1,5 V
