Where P is the maximum output power

rating of the transmitter in watts (W)

according to the transmitter manufacturer

and d is the recommended separation

distance in meters (m).

As determined by an electromagnetic

site survey, field strengths from fixed RF

transmitters should be less than the

compliance level in each frequency

range.

Interference may occur in the vicinity of

equipment marked with the following

symbol:

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 strengths from fixed transmitters, such as base stations for radio (cellular/cordless)

telephones and land mobile radios, amateur radio, AM and FM radio broadcasts, and TV

broadcasts, cannot be predicted theoretically with accuracy. An electromagnetic site survey

should be considered to assess the electromagnetic environment for fixed RF transmitters.

Suppose the measured field strength in the location in which the SE-1200 Pro&SE-1201 Pro

ECG is used exceeds the applicable RF compliance level above. In that case, the SE-1200

Pro&SE-1201 Pro ECG should be observed to verify regular operation. If abnormal

performance is monitored, additional measures may be necessary, such as reorienting or

relocating the SE-1200 Pro&SE-1201 Pro ECG.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765

MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz

to 40.70 MHz. The amateur radio bands between 0.15 MHz and 80 MHz are 1.8 MHz to 2.0

MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz to 5.4 MHz, 7 MHz to 7.3 MHz, 10.1 MHz to 10.15 MHz,

14 MHz to 14.2 MHz, 18.07 MHz to 18.17 MHz, 21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99

MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0 MHz.
