Portable and mobile radio devices
should not be used closer to a Pro Lift
Cacero series hoist, including cabling,
than the recommended protective
distance, which is calculated according
to an equation applicable to the
relevant transmission frequency.
Recommended protective distance
80 MHz to 800 MHz
800 MHz to 2,5 GHz
where P is the rated output of the
transmitter in watts (W) according
to the transmitter manufacturer‘s
specification and d is the
recommended protective distance in
metres (m).
The field strength of stationary radio
transmitters at all frequencies, as de-
termined by local testinga , should be
less than the compliance level.b

Disturbances may occur around devices
bearing the following symbol.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: This guideline may not be applicable in all cases. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
Field strengths from stationary transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio stations, AM and FM radio, TV transmitters, theoretically cannot be predicted with
complete accuracy. To assess the electromagnetic environment with regard to stationary transmitters, a site survey of
electromagnetic phenomena should be considered. If the measured field strength in the location in which the ProLift
Cacero is to be used exceeds the above compliance level, the ProLift Cacero should be observed to verify that it is
functioning as specified. If unusual performance characteristics are observed, additional measures may be necessary,
such as re-orientating or relocating the ProLift Cacero series hoist.
Across the 150 kHz to 80 MHz frequency range, field strengths should be less than 3 V/m.
The Pro Lift Cacero is intended for operation in an ELECTROMAGNETIC ENVIRONMENT as specified below. The customer
or user of the ProLift Cacero should ensure that it is being operated in such an environment.
