         Warning 

If You need mains adapter, You may purchase it separately. Use only the mains 
adaptor AD-155. The use of any other adapters can make your warranty void.

4.3. Tube connection

Insert the cuff  tube into the opening provided on the left side of the instrument, as shown 
in the diagram.

4.4. Changing the language

You can change the language by using the following procedure:
1. While the device is switched off , hold the     button until you hear the word «Russian» and the display shows the letters <LAn>.

2. Keep the buttons pressed. The voice switches automatically to the next: «English» and then to «Kazakh». The procedure is changing back and forth 
at every 2 seconds.
3. Confi rm the selection by releasing the     button until you hear the name of the desired language.

5. Carrying out a measurement
5.1. Before the measurement:

• Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these factors infl uence the measurement result. Try and fi nd 
time to relax by sitting in an armchair in a quiet atmosphere for about ten minutes before the measurement.
• Remove any garment that fi ts closely to your upper arm.
• Measure always on the same arm (normally left).
• Attempt to carry out the measurements regularly at the same time of day, since the 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 eff orts by the patient to support the arm can increase the blood-pressure. Make sure you are in a comfortable, relaxed position and do not activate any 
of the muscles in the measurement arm during the measurement. Use a cushion for support if necessary.
• If the arm artery lies considerably lower (higher) than the heart, an erroneously higher (lower) blood-pressure will be measured! (Each 15cm diff erence in 
height results in a measurement error of 10mmHg)
• Cuff s that are too narrow or too short result in false measurement values. Selecting the correct cuff  is of extraordinary importance. The cuff  size is depend-
