GUIDANCE AND MANUFACTURER'S DECLARATION
The Free Action is intended for use in the electromagnetic environment speci ed below. The customer or the user of
the Free Action should assure that it is used in such an environment.

Electromagnetic propagation is a ected by absorption and re ection from structures, objects and people.
a. Field strengths from xed 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 xed RF
transmitters, an electromagnetic site survey should be considered. If the measured eld strength in the location in which the Free Action is used exceeds
the applicable RF compliance level above, the Free Action should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Free Action.
b. Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATIONS EQUIPMENT AND THE FREE ACTION
The Free Action is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the Free Action can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the Free Action as recommended below,
according to the maximum output power of the communications equipment.
