Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The Element System is intended for use in the electromagnetic environment specified below.
The customer or the user of the Element System should assure that it is used in such an
environment.

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 Element System is used exceeds the
applicable RF compliance level above, the Element System should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as re-orienting or relocating the Element System.
Electromagnetic Environment -
Guidance
Portable and mobile RF communications
equipment should be used no closer
to any part of the Element System,
including cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.

Recommended separation distances between portable and mobile RF communications equip-
ment and the Element System
The Element System is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the Element System can help
prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the Element 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 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.
