RECOMMENDED SEPARATION DISTANCE BETWEEN PORTABLE AND MOBILE RF COMMUNICATIONS EQUIPMENT AND
THE ManaSport
The ManaSport is intended for use in the electromagnetic environment specified below.
The customer or the user of the ManaSport should assure that it is used in such an environment.
Conducted RF
IEC61000-4-6
Portable and mobile RF communications equipment should be used no closer to any part of the ManaFuse,
including cables, than the recommended separation distance calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
150 KHz to 80 MHz
80 MHz to 800 MHz
800 MHz to 2.5 GHz
Radiated RF
IEC61000-4-3
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.
The ManaSport is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the ManaSport can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the ManaSport as
recommended below, according to the maximum output power of the communications equipment.

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 the fixed RF transmitters, an electromagnetic site survey should
be considered. If the measured field strength in the location in which the ManaSport is used exceeds the applicable RF compliance level above, the ManaSport should be
observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the ManaFuse.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
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.
For transmitters rated at a maximum output power not listed above, the recommended separation distance 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.
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).
