The Omron RS6 wrist blood pressure monitor is supplied with an easy to understand, clear instructions in small folded poster size (about Din-A-2) and two 1.5V AAA alkaline batteries and is located in a small hard-shell box with the inside of the lid integrated image Quick Start Guide. The device itself is about 8 x 6 cm tall and just 1.5 cm thick. The attached cuff is attached to the wrist and fixed with a velcro. Press Start button and away you go! If it is not attached firmly enough or the arm during the measurement kept too low or too high (default: heart level), this is indicated by simple icons as irregular heartbeats or movements during the measurements. The wrong arm height you can still correct during the measurement, the device responds. The measurements are made almost completely silent. Up to 90 readings are stored and can be later retrieved or deleted. Although always it is said that wrist instruments are as arm gauges accurate, but I have also had the latter and made with both devices more measurements consecutively (with appropriate breaks in between). Result: only small, insignificant deviations! CONCLUSION: An easy to use, safe device for casual and advanced players!
