[. . . ] Information about blood pressure Blood pressure does not remain constant but is continually changing. In the morning the blood pressure is lower than in the evening and it is at its lowest during sleep. it is also influenced by eating , smoking , stress and bodily exertion. High blood pressure is not normally noticeable immediately by the occurrence of particular complaints. [. . . ] Most persons have a higher blood pressure on their left wrist. Therefore the measurement should be taken on the left wrist. If the blood pressure is higher on the right wrist, the measurement should be taken on the right wrist. Close the cuff with the Velcro fastener. The cuff should fit snugly around the wrist. When relaxed, place your elbow on the table with the forearm raised so that your wrist is at the same height as your heart. Only use batteries of the given specifications and follow the polarisation markings in the battery compartment. Never mix old with new batteries, or batteries of different manufacture. Slide the lid back into its original position. Used batteries should not be disposed with normal household refuse. Note on cuff size: The unit must only be used in combination with the CW 42 cuff (wrist circumference 13. Measuring your blood pressure The unit inflates the cuff to a pressure of about 180 mmHg. the display indicates the pressure of the cuff as it rises. In case this pressure is not sufficient, the unit inflates the cuff by a further 50 mmHg. Once inflated, the pump is switched off and the air in the cuff escapes automatically. If not already the case, you should now keep your arm completely still and not speak. As soon as the unit registers the first beats, the symbol blinks in time with the pulse rhythm and the falling pressure in the cuff is displayed. After the measurement; the built-in solenoid valve opens automatically to rapidly release the remaining pressure in the cuff. When the memory store is full (30 18 If symbol appears following a completed measurement, it is recommended that the measurement is repeated while holding the arm motionless (see also page 21). A renewed display of symbol following the repeat measurement with the arm being held motionless, can be an indication of irregular heart beat. Discuss this matter with your GP on your next visit. The unit switches off automatically after approximately one minute. [. . . ] Used batteries and defective electronic devices do not belong into the household waste. They can be deposited at special centres. A) Functional testing Functional testing of the unit can only be performed on human subjects or using a suitable simulator. B) Leak testing of the pressure circuit and error testing of the display Please note: a) Prior to testing, separate the cuff from the unit (after having first removed the screws in the battery compartment).
