EMC Information
This equipment has been tested and found to comply with the limits for a Class A digital devices,
pursuant to Part 15 of the FCC Rules. This medical device equipment is suitable for use 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. 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. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
The maximum wireless signal rate for the system is derived from IEEE Standard 802.11b/g/n
specifications. Actual data throughput will vary. Network conditions and environmental factors,
including the volume of network traffic, building materials and construction, and network overhead,
may lower actual data throughput rate. Environmental conditions will adversely affect wireless signal
range.
