MERK Hvis det er nødvendig for å oppnå IMMUNITETSTESTNIET, kan avstanden mellom
senderantennen og ME-UTSTYRET eller ME-SYSTEMET reduseres til 1 m. 1 m testavstand er tillatt i
henhold til IEC 61000-4-3.
a) For noen tjenester er bare opplink-frekvensene inkludert.
b) Bæreren skal moduleres ved hjelp av et 50 % driftssyklus firkantbølgesignal.
c) Som et alternativ til FM-modulasjon. 50 % pulsmodulasjon ved 18 Hz kan brukes fordi selv om det ikke
representerer faktisk modulasjon, ville det være det dårligste tilfellet.
