Important information regarding Electro Magnetic Compatibility (EMC)

With the increased number of electronic devices such as PC’s and mobile (cellular) telephones, medical devices in 
use may be susceptible to electromagnetic interference from other devices. Electromagnetic interference may result 
in incorrect operation of the may result in incorrect operation of the medical device and create a potentially unsafe 

situation.

Medical devices should also not interfere with other devices. In order to regulate the requirements for EMC 
(Electro Magnetic Compatibility) with the aim to prevent unsafe product situations, the EN60601-1-2:2007 
standard has been implemented. This standard defines the levels of immunity to electromagnetic interferences as 
well as maximum levels of electro magnetic emissions for medical devices.
This medical device manufactured by OMRON Healthcare conforms to this EN60601-1-2:2007 standard for both 
immunity and emissions. Nevertheless, special precautions need to be observed:

Do not use mobile (cellular) telephones and other devices, which generate strong electrical or electromagnetic
fields, near the medical device. This may result in incorrect operation of the unit and create a potentially unsafe
situation. Recommendation is to keep a minimum distance of 7 m. Verify correct operation of the device in case

the distance is shorter. 

Further documentation in accordance with EN60601-1-2:2007 is available at OMRON HEALTHCARE EUROPE
