Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The SPIDER2 is intended for use in the electromagnetic environment specified below. The customer or user of the SPIDER2 should assure that it is used in such an
environment.
Immunity Test IEC 60601 Test Level
Conducted RF 3 Vrms
IEC 61000-4-6 150 KHz to 80 MHz
Radiated RF 3 V/m
IEC 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 absorption and reflection from structures, objects, and people.
a Field strengths from fixed transmitters, such as base stations for radio, (cellular/cordless) telephones, land mobile radios, amateur radios, AM and FM radio broadcasts, and TV
broadcasts 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 SPIDER2 is used exceeds the applicable RF compliance level above, the SPIDER2 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the SPIDER2.
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
