Nicolet EEGwireless32/64 Amplifier - Electromagnetic Compatibility
(EMC) Information
Portable and mobile RF communications equipment can affect the Nicolet EEGwireless32/64 amplifier. Install
and operate the Nicolet EEGwireless32/64 amplifier according to the EMC information presented on this page
and the next 4 pages.
The Nicolet EEGwireless32/64 amplifier has been tested for EMC emissions and immunity as a standalone
instrument. Do not use the Nicolet EEGwireless32/64 amplifier adjacent to or stacked with other electronic
equipment. If adjacent or stacked use is necessary, the user should verify normal operation in the configuration
Recommended separation distances between portable and mobile RF
communications equipment and the Nicolet EEGwireless32/64 amplifier
The Nicolet EEGwireless32/64 amplifier is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Nicolet EEGwireless32/64 amplifier can help prevent
electromagnetic interferences by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Nicolet EEGwireless32/64 amplifier 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 higher frequency range applies.
Note 2 These guidelines may not apply to all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
