Electromagnetic Immunity for Non-life-
supporting Equipment
Table A-3.
Electromagnetic compatibility (EMC) immunity guidelines and declarations for non-life-
supporting equipment (such as GeoScan components)
GeoScan systems are intended for use in the electromagnetic environment specified
below. The customer or user of a GeoScan system should ensure that it is used in such an
environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of the GeoScan system,
including cables, than the
recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation:

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). Field strengths from fixed RF
transmitters, as determined by the
electromagnetic site survey,

less than the compliance level in each
frequency range.

occur in the vicinity of equipment
marked with the following symbol:
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
