SAFETY NOTES FOR BATTERIES
Please check first of all that the unit is complete.
The following parts are included as standard:
Please contact your supplier if you notice any transport damage on unpacking the unit.
Blood pressure is the pressure created in the blood vessels by each heart beat. When the heart contracts (= systole) and pumps blood into the arteries, it brings about a rise in pressure. The highest value is known as the systolic pressure and is the first value to be measured. When the cardiac muscle relaxes to take in fresh blood, the pressure in the arteries also falls. Once the arteries are relaxed, a second reading is taken – the diastolic pressure.
The MEDISANA BU A50 is a blood pressure unit which is used to measure blood pressure at the upper arm. The measurement is carried out by a microprocessor, which, via a pressure sensor, measures the vibrations resulting from the inflation and deflation of the cuff over the artery.
These values have been specified by the World Health Organisation (WHO) without making any allowance for age.
Low blood pressure | systolic <100 | diastolic <60 |
Normal blood pressure (green display area ) | systolic 100 - 139 | diastolic 60 - 89 |
Forms of high blood pressure / hypertension
Mild hypertension (yellow display area ) | systolic 140 – 159 | ) diastolic 90 – 99 |
Moderate hypertension (orange display area ) | systolic 160 – 179 | ) diastolic 100 – 109 |
Severe hypertension (red display area ) | systolic >_180 | diastolic >_110 |
Blood pressure that is too low represents just as great a health risk as blood pressure that is too high! Fits of dizziness may lead to dangerous situations arising (e.g. on stairs or in traffic)!
Insert / replace batteries
You must insert the batteries provided before you can use your unit. The lid of the battery compartment is located on the underside of the unit. Open it, remove it and insert the 4 AA LR6 type 1.5 V batteries supplied. Ensure correct polarity when inserting the batteries (as marked inside the battery compartment). Close the battery compartment. Replace the batteries if the change battery symbol appears on the display or if nothing appears on the display after the unit has been switched on.
Alternatively, you can use the unit with a special mains adaptor (MEDISANA Art.–No. 51125). This connects to the socket provided at the back of the unit. In this case the batteries remain in the unit. Inserting the connector into the back of the blood pressure monitor switches the batteries off mechanically. It is necessary, therefore, to plug the mains adaptor into the mains socket first of all and then to connect it to the blood pressure monitor. If the blood pressure monitor is no longer being used, first remove the connector from the blood pressure monitor and then pull the mains adaptor out of the mains socket. Doing this means that the date and time will not have to be reset each time.
After the cuff has been appropriately positioned, the measurement can begin:
If it is necessary to interrupt a blood pressure measurement for any reason (eg. the patient feels unwell) the START/STOP button can be pressed at any time. The device immediately decrease the cuff pressure automatically.
This unit features 4 separate memories, each with a capacity of 60 memory slots. Results are automatically stored in the memory selected by the user. Press the + or - button when power off, the latest 3 times average will be shown, press the + button again, the oldest measurement value will be shown, or press the - button again, the latest measurement will be shown, as well as subsequent measurements can be displayed one after the other by pressing the + or - button each time. If you have reached the final entry and do not press a button, the unit automatically switches itself off after approximately 120 seconds in memory recall mode. Memory recall mode can be exited at any time by pressing the START/STOP button , which will also switch the unit off. The oldest value is deleted if 60 measured values have been stored in the memory and a new value is saved.
If you are sure that you want to permanently remove all stored memories, press the SET button for 6 times until CL appears. Press the START/STOP button , CL will flash for 3 times to clear all the memories. After this press +- oder - button, M and 'no' will be shown on the display which mean that no memory in store.
Error indicators
The following symbol will appear on the display when measuring abnormal.
Symbol | Cause | Correction |
E-1 | Weak signal or pressure change suddenly | Wrap the cuff properly. Remeasure with correct way. |
E-2 | External strong disturbance | When near cell phone or other high radiant device, the measurement will be failed. Keep quiet and no chatting when measure. |
E-3 | It appears error during the process of inflating | Wrap the cuff properly. Make sure that he plug is properly inserted in the unit. Remeasure. |
E-5 | Abnormal blood pressure | Repeat the measurement after relax for 30 mins. If get unusual readings for 3 times, please contact your doctor. |
Low battery | The batteries are too low or empty. Replace all four batteries with new 1.5 V type AA LR6 batteries. |
Problem | Check | Cause and solutions |
No power | Check the battery power Check the polarity position | Replace new one Installation for proper placement of the batteries polarities |
No inflation | Check whether the plug is inserted correctly Check whether the plug is broken or leak | Insert into the air socket tightly Change a new cuff |
Err and stop working | Check whether move the arm Keep the body peaceful when inflate Check if chatting when measured | Keep quiet when measure |
Cuff leak | Check whether the cuff wrap too loose Check whether the cuff broken | Wrap the cuff tightly Change a new cuff |
Please contact the distributer if you can't solve the problem. Do not disassemble the unit by yourself.
Remove the batteries before cleaning the unit. Clean the unit using a soft cloth lightly moistened with a mild soapy solution. Never use abrasive cleaning agents, alcohol, naphta, thinner or gasoline etc.. Never immerse the unit or any component in water. Be cautiious not to get any moisture in the main unit. Do not wet the cuff or attempt to clean the cuff with water. Using a dry cloth, gently wipe away any excess moisture that may remain on the cuff. Lay the cuff flat in an unrolled position and allow the cuff to air dry.
Do not expose the unit to direct sunlight; protect it against dirt and moisture. Do not subject the unit to extreme hot or cold temperature. Keep the unit in the storage case when no use. Store the unit in a clean and dry location.
