Electromagnetic Compatibility: Guidance and Manufacturer's Declaration-Electromagnetic Immunity
Immunity test EN60601 test level
Conducted RF EN 3 Vrms
61000-4-6 150 KHz to 80 MHz
Radiated RF EN 3V/m
61000-4-3 80 MHz to 2.5 GHz
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radio, amateur
radio, AM and FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment
due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the MAC 600
is used exceeds the applicable RF compliance level above, the MAC 600 should be observed to verify normal operation. If abnormal performance
is observed, additional measures may be necessary, such as re-orienting or relocating the MAC 600.
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
