How often should my Omron Blood Pressure Monitor be calibrated?
Under normal use we recommend you check the calibration of your unit 5 years from the date of purchase. If you use your unit 5 times a day or more have the calibration of the unit checked annually. You must send your unit to the repair department at Omron Healthcare for this service. When an individual situation occurs that may have damaged the unit such as; dropping the unit on the floor, spilling water on the unit, or exposing the unit to an extreme temperature change the unit should be inspected by the repair department.
