System IV Instructions for Use

a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio 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 Thymatron® System is used exceeds the
applicable RF compliance level above, the Thymatron® System should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating
the Thymatron® System.
b
Over the frequency range 150 kHz to 80MH, field strengths should be less than [V1] V/m
Recommended separation distances between portable and mobile RF communications
equipment and the Thymatron® System
Thymatron® ECT Systems are intended for use in the electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Thymatron® System can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) ant the Thymatron® System as recommended below, according to the
maximum output power of the communications equipment specified below. The customer or the user of a
Thymatron® System should assure that it is used in such an environment.
