256 EN MEDUMAT Standard
2
WM 68071 05/2021
14 Appendix
Guidelines and manufacturer's declaration – electromagnetic immunity
MEDUMAT Standard
2
has been tested for immunity against the radio services listed below.
If the field strength measured at the site where MEDUMAT Standard
2
is used exceeds the upper
compliance level, MEDUMAT Standard
2
should be monitored to ensure it is functioning as intended.
If unusual performance characteristics are noted, additional measures may prove necessary such as
changing the orientation or moving MEDUMAT Standard
2
to another site.

a
Only the frequencies for radio connection of mobile communication devices to the base station (en: uplink)
are included in the table for some radio services.
b
The carrier must be modulated with a square-wave signal with a 50 % duty cycle.
c
As an alternative to frequency modulation (FM), it is also possible to use pulse modulation with a 50 %
duty cycle of 18 Hz, as this, although not the actual modulation, would reflect the worst case scenario.
