Sensitive measuring devices must be checked from time to time for accuracy and leakage. We recommend
that the performance should be checked every 2 years.
GUIDANCE AND MANUFACTURE’S DECLARATION
ELECTROMAGNETIC EMISSION
The Digital Blood Pressure Monitor is intended for use in the electromagnetic environment specified below. The
customer of the user of the Digital Blood Pressure Monitor should assure that it is used in such an environment.
Emission test Compliance Electromagnetic environment – guidance
Radio frequency (RF) emissions
CISPR 11
Group 1
The Digital Blood Pressure Monitor use RF energy only for
its internal function. Therefore, its RF emissions are very
low and are not likely to cause any interference in nearby
electronic equipment.
RF emissions
CISPR 11
Class B
The Digital Blood Pressure Monitor is suitable for use in all
establishments other than domestic and those directly
connected to the public low-voltage power supply network
that supplies buildings used for domestic purposes.
