Separation distance between any electronic
parts of ICS AirCal and any RF wireless com-
munication equipment must be more than
30 cm (11.8 inches).
Note 1
: At 80 MHz and 800 MHz the separation distance for 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 and land mobile radios, 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 ICS AirCal is used exceeds the applicable RF com-
pliance level above, the ICS AirCal should be observed to verify normal operation. If abnormal performance is observed, additional measures might be neces-
sary, such as reorienting or relocating ICS AirCal.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and ICS AirCal
The ICS AirCal is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the ICS
AirCal can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (trans-
mitters) and the ICS AirCal as recommended below, according to the maximum output power of the communications equipment.
