SPECIFICATIONS
Guidance and manufacturer’s declaration - electromagnetic emissions
The table is intended for use in the electromagnetic environment specified below. The customer or the
user of the table should assure that it is used in such an environment.
Emissions Test Compliance Electromagnetic environment - guidance
RF emissions
CISPR 11
Group 1
The table 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 table is suitable for use in all establishments
other than domestic and those directly con-
nected to the public low-voltage power supply
network that supplies buildings used for domestic
purposes.

Recommended separation distances
between portable and mobile RF communications equipment and the table
The table is intended for use in the electromagnetic environment in which radiated RF disturbances
are controlled. the customer or the user of the table can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the table as recommended below, according to the maximum output 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 maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer. 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.
