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 and land mobile radios, amateur radio, AM and FM radio broad-
cast 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 CHECKY is
used exceeds the applicable RF compliance level above, the CHECKY should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the CHECKY.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than
3V/m.
Table 6 Recommended separation distances between portable and mobile RF
communications equipment and the EQUIPMENT or SYSTEM – For ME EQUIP-
MENT or ME SYSTEM that are not LIFE-SUPPORTING
between portable and mobile RF communications equipment at the CHECKY
The CHECKY is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the CHECKY can help
prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmittters) and the CHECKY as
recommended below, according to the maximum output power of the communications
equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be determined 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.
NOTE 1 At 80MHz and 800MHz, the separation distance for the higher frequency
range applies.
NOTE 4 These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
