Thank you for purchasing the OMRON MIT5s Connect Automatic Upper Arm Blood 
Pressure Monitor.
Your new blood pressure monitor uses the oscillometric method of blood pressure 
measurement. This means the monitor detects your blood movement through your brachial 
artery and converts the movements into a digital reading. An oscillometric monitor does not 
need a stethoscope so the monitor is simple to use.
Intended Use
This device is a digital monitor intended for use in measuring blood pressure and pulse rate in 
adult patient population who can understand this instruction manual with the arm 
circumference range printed on the arm cuff. The device detects the appearance of irregular 
heartbeats during measurement and gives a warning signal with the measurement result.
