Electromagnetic compatibility
Although designed to offer protection against
harmful interference in a home use
environment, NovoPen Echo® Plus generates,
uses and can radiate radio frequency (RF)
energy. Interference may therefore occur under
certain conditions.
Your injection is not controlled by electronics,
and dose accuracy will therefore not be affected
by electromagnetic disturbance.
