protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, 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.
Operation is subject to the following two conditions:
1) this device may not cause interference and
2) this device must accept any interference, including interference that may cause undesired
operation of the device.

Introduction
The SMN-800/900 SmartNODETM RFID Receiver is an integral component of the
SmartSense Wireless Vital Signs and Location Tracking System. The system is
designed for wireless and automated measurement and recording of patient vital
signs and for location tracking of patients and high-value assets.
The SMN-800/900 SmartNODETM RFID Receiver is a LAN-enabled receiver for
receiving data transmitted by the SmartSenseTM series of wireless sensors and
monitors. The receiver uploads data received from the sensors to the
SmartSenseTM database via its built in Ethernet LAN interface.
In a typical installation, the receivers are to be installed at strategic locations in the
hospital in a manner to meet the specific coverage requirement of the application.
The receivers being Ethernet LAN capable lend themselves well to deployment
using standard Ethernet LAN equipment and infrastructure.
