Note: If necessary, the distance between the transmitting antenna and MEDUCORE Standard
reduced to 1 meter to achieve the interference immunity test level. The 1 meter test distance is permitted
according to IEC 67000-4-3.
a)
For some radio services, only the frequencies for the uplink have been included in the table.
b)
The HF carrier must be modulated with a square wave with a 50 % signal ratio.
c)
As an alternative to frequency modulation (FM), pulse-width modulation with a 50 % signal ratio at
18 Hz can be used, as this would represent the worst-case scenario even if it is not the actual modulation.

A characteristic of the CARDIObiphasic shock pulse is that it limits
the maximum current. This greatly reduces the risk of myocardial
damage, which is mainly caused by excessively high electric
currents, especially where patient impedance is low.
