Electromagnetic Immunity (continued)
NOTE 1: At 80 MHz and 800 MHz, the higher frequency 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 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 where the
hoist
is used exceeds the applicable RF
compliance level above, the
hoist
should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the
hoist
.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distance Between -
Portable and Mobile RF Communications Equipment and the Ceiling
hoist
or Equipment and Systems that are not Life-Supporting
Recommended separation distances between portable and mobile RF communications
equipment and the Monarch Ceiling
hoist
.
The Monarch Ceiling
hoist
is intended for use in electromagnetic environments in which
radiated RF disturbances are controlled. The customer or the user of the
hoist
can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communication equipment (transmitters) and the ceiling
hoist
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 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.
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.
