portable and mobile RF communications equipment and the Instrument.
The Instrument is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the Instrument can help prevent electromagnetic interferences
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the Instrument 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.

Electromagnetic environment - guidance
The Instrument uses RF energy only for its internal
function.
Therefore, its RF emissions are very low and are not
likely to cause any interference in nearby electronic
equipment.
The Instrument is suitable for use in all commercial,
industrial, business, and residential environments.
