Guidance and manufacturer's declaration - electromagnetic immunity
The SCOUT System is intended for use in the electromagnetic environment specified
below. The customer or user of the SCOUT System should assure that it is used in such an
environment.

NOTE 1: At 80MHz and 800MHz, 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 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 in which the SCOUT System is used
exceeds the applicable RF compliance level above, the SCOUT System should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessarily, such as reorienting or relocating the SCOUT System.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m*.
Recommended separation distances between portable and mobile RF
communications equipment and the SCOUT System
The SCOUT System is intended for use in the electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the SCOUT System can
help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the SCOUT System
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 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.
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.
