Product compliance
c
Renishaw plc declares that the VIONiC™ encoder system complies with the applicable standards
and regulations. A copy of the EU declaration of conformity is available from our website at
www.renishaw.com/productcompliance
FCC compliance
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
The user is cautioned that any changes or modications not expressly approved by Renishaw plc or
authorised representative could void the user’s authority to operate the equipment.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant
to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment
in a residential area is likely to cause harmful interference in which case the user will be required to
correct the interference at his own expense.
NOTE: This unit was tested with shielded cables on the peripheral devices. Shielded cables must be used
with the unit to ensure compliance.
