• Do not use on neonatal patients.
• Do not intend to use on pregnant or pre-eclamptic patients
• Keep Product in proper packing. Any wrong use will cause harmful injury to the patient or  affect the blood pressure.
• Too frequent measurements can cause injury to the patient due to blood flow interference. The application of the cuff over a wound can cause further injury.
• The application of the cuff and its pressurization on any limb where intravascular access or therapy, or an arteriovenous (A-V) shunt is present because of temporary interference to blood flow and could result in injury to the patient.
• Do not let the cuff and its pressurization on the arm on the side of a mastectomy Pressurization of the cuff can temporarily cause loss of function if simultaneously used monitoring ME equipment on the same limb.
• Please check that operation of the automated sphygmomanometer does not result in prolonged impairment of patient blood circulation.
• Not intended to be used together with HF surgical equipment.
• Do not forget: self-measurement means control, not diagnosis or treatment. Unusual values must always be discussed with your doctor. Under no circumstances should you alter the dosages of any drugs prescribed by your doctor.
• The pulse display is not suitable for checking the frequency of heart pacemakers!
• In cases of cardiac irregularity (Arrhythmia), measurements made with this instrument should only be evaluated after consultation with the doctor.

Electromagnetic interference 
The device contains sensitive electronic components (Microcomputer). Therefore, avoid strong electrical or electromagnetic fields in the direct vicinity of the device (e.g. mobile telephones, microwave cookers). These can lead to temporary impairment of the measuring accuracy.

Important information on the subject of blood-pressure and its measurement

How does highnow blood-pressure arise?

As your heart beats, ii pumps your blood round your body so that your muscles can gel all the energy and oxygen they need. To do this, your heart pushes your blood through a network of blood vessels called arteries. As the blood travels through the arteries it pushes against the sides of these blood vessels and the strength of this pushing is called your blood pressure.

As your heart squeezes and pushes your blood through your arteries, your blood pressure goes up. As your heart relaxes, your blood pressure goes down. So, with each heartbeat, your blood pressure will rise to a maximum level and then fall to a minimum level.

Which values are normal? 
Blood pressure is too high if at rest, the diastolic pressure is above 90 mmHg and/or the systolic blood-pressure is over 160 mmHg. In this case, please consult your doctor immediately. Long-term values at this level endanger your health due to the associated advancing damage to the blood vessels in your body.

Should the systolic blood-pressure values lie between 140 mmHg and 160 mm Hg and/or the diastolic blood-pressure values lie between 90 mm Hg and 100 mm Hg, likewise, please consult your doctor. With blood-pressure values that are too low, i.e. systolic values under 100 mm Hg and/or diastolic values under 60 mmHg, likewise, please consult your doctor. Even with nonmal blood-pressure values, a regular self-check of your blood-pressure is recommended. In this way you can detect possible changes in your values early and react appropriately.

If you are undergoing medical treatment to control your blood pressure, please keep a record of the level of your blood pressure by carrying out regular self-measurements at specific times of the day. Show these values to your doctor. Never use the results of your measurements to alter independently the drug doses prescribed by your doctor.

Table for classifying blood-pressure values (unit: mm Hg) according to World Health Organization:

Further Information 
With each press of the button (TIME, MEMORY) one input is made (e.g. switching over from hours to minutes mode, or altering the value by +1). However, if you keep the respective button depressed, you can switch more quickly to find the desired value. 

Carrying out a measurement

Before the measurement 

• Avoid eating, smoking as well as all forms of exertion before the measurement. All these factors influence the measurement result. Try and find time to relax by sitting in an armchair in a quiet atmosphere for about ten minutes before the measurement.
• Measure always on the same arm (normally left).
• Attempt lo carry out the measurements regularly at the same time of day, since the blood -pressure changes during the course of the day.

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 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. 
• The performance of the automated sphygmomanometer can be affecled by extremes of temperature, humidity and altitude. 
• Avoid compression or restriction of the connection tubing. 
• A loose cuff causes false measurement values. 

Filling the cuff 
Insert air connector into air outlet shown in left photo and please make sure the fitting of the air connector is tight completely and proper to avoid air leakage.

• The distance between the edge of cuff and the elbow should be approx. 2~3cm.
• Secure the cuff with the Velcro fastener, so that ii lies comfortably and not too light, whereby no space should remain between the cuff and the arm.
• Lay the arm on a table, with the palm upwards. Support the arm a little with a rest (cushion), so that the cuff rests at about the same height as the heart. Take care, that the cuff lies free. Remain so for 2 minutes sitting quietly, before beginning with the measurement. 

• Let legs uncrossed, feel flat on the floor, back and arm supported.

  

Measuring procedure 
After the cuff has been appropriately positioned, the measurement can begin:

• Press the ON/OFF button, the pump begins to inflate the cuff. In the display, the increasing cuff-pressure is continually displayed.

  

• After reaching the inflation pressure, the pump stops and the pressure slowly falls away. The cuff-pressure (large characters) is displayed during the measurement. When the device has detected the pulse, the heart symbol in the display begins to blink for every pulse beat. The measured systolic and diastolic blood -pressure values as well as the pulse frequency are now displayed. 
  Example (Fig.): Systole 118, Diastole 73, Pulse 75 
  The measurement results are displayed, until you switch the device off. If no button is pressed for 3 minutes, the device switches automatically off, to save the batteries. P Monitor 103, 

  

• Start by ensuring the batteries are properly inserted. 
• Next, place the cuff around your upper arm, making sure it is not too tight or too loose. 
• Press the power button to turn on the device. The monitor will automatically inflate the cuff; wait until it deflates to get your reading.
• For assembly, simply attach the cuff to the main unit using the provided connector. 
• Configuration is minimal as the device is ready to use out of the box. 
• For pairing with other devices, this model does not support Bluetooth or Wi-Fi connectivity but can be used independently.

Discontinuing a measurement 
If ii is necessary to interrupt a blood pressure measurement for any reason (e.g. the patient feels unwell), the "ON/OFF" power button can be pressed at any time. The device then immediately lowers the cuff-pressure automatically.

Memory - storage and recall of the measurements

The blood-pressure monitor automatically stores each of the last 120 measurement values. By pressing the MEMORY button, an average value of the last 3 measurements as well as the last measurement and the further last 120 measurements (MR 119,MR118 ... ,MR1 )can be displayed one after the other (MR1: Values of the last measurement) (MR2-MR120: Values of the measurement before MR1)

Pay attention that the maximum memory capacity is not exceeded. When the memory is full, the old values are automatically overwritten with new ones.

Memory- cancellation of all measurements! 
Before you delete all readings stored in the memory, make sure you will not need to refer to the readings at a later date. Keeping a written record is prudent and may provide additional infonmation for your doctor's visit. In order to delete all stored readings, press the MEMORY button for at least 5 seconds, the display will show the symbol «CL» and then release the button. To permanently clear the memory, Press the MEMORY button while «CL» is flashing.

Appearance of the Heart Arrhythmia Indicator for early Detection

This symbol .); indicates that certain pulse irregularities were detected during the measurement.  In this case, the result may deviate from your nonmal 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.

Care and Maintenance, Recalibration

1. Do not expose the device lo extreme temperatures, humidity, dust or direct sunlight.
2. The cuff contains a sensitive air-light bubble. Handle this carefully and avoid all types of straining through twisting or buckling. 
3. Clean the device with a soft, dry cloth. Do not use petrol, thinners or similar solvent. Spots on the cuff can be removed carefully with a damp cloth and soap. The cuff must not be washed!
4. Do not drop the instrument or treat it roughly in any way. Avoid strong vibrations.
