RF emissions CISPR 11
Group 1
The Wrist Array Coil 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.
RF emissions CISPR 11
Class A
The Wrist Array Coil is suitable in all
establishments other than domestic, and
those directly connected to the public low-
voltage power supply network that supplies
buildings used for domestic purposes.

It is mandatory for the RF shielding effectiveness and filter attenuation in the shielded location to be verified
and to ensure that the actual values meet or exceed the specified minimum values.
Cables or options other than those used for the current product must not be used. If cables or options other
than those used for the current product are used, the EMI performance may deteriorate
