ADC e-sphyg 2 - Electromagnetic Immunity and Distancing

29

The 9002 is intended for use in the electromagnetic environment specified below.

The customer or the user of the 9002 should assure that it is used in such an environment.

Table 4 - Guidance and manufacturer’s declaration - electromagnetic immunity -

The 9002 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of

the 9002 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications

equipment (transmitters) and the 9002 as recommended below, according to the maximum output power of the communications equipment.

Rated maximum output Separation distance according to frequency of transmitter, m

power of transmitter, W 150 kHz to 80 MHz, d=[3.5/V1]P 80 MHz to 800 MHz, d=[3.5/E1]P 800 MHz to 2.5 GHz, d=[7/E1]P

0.1 0.38 O.38 0.73

1 1.2 1.2 2.3

10 3.8 3.8 7.3

100 12 12 23

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using

the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according

to the transmitter manufacturer.

NOTE1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

NOTE2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures,

objects and people.

Table 6 - Recommended separation distances between portable and mobile RF communications equipment and the 9002 -

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.

Field strength from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radios

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 9002 is used exceeds the applicable RF compliance level

above, the 9002 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or

relocating the 9002.
