national standard for EMC with medical devices. See the Manufacturers Declaration for details. Electromagnetic Compatibility Testing During the test program, the BP Unit was subjected to many EMC tests, including both international standard and Agilent proprietary tests. During most of the testing, no anomalies were observed. For one of the tests, EN 61000-4-3 Radiated Immunity reduced perfor-

mance was observed. EN 61000-4-3 specifies that the product be sub-

jected to a field of 3 Volts/meter over a frequency range of 26 to 1000 MHz with no degradation of performance or loss of function below the performance level specified when equipment is operated as intended. At many of the test frequencies over the specified range, no anomalies were observed. However, at a number of test frequencies, radio commu-

nications from the BP Unit to the M3812A Home Hub was disrupted. These reduced levels are as low as 0.48 V/m in the range from 902.278 MHz to 948.302 MHz. The phenomena discussed above are not unique to this BP Unit, but are characteristic of radio instrumentation in use today. The Home Hub is a radio receiver, and its reception of M3815A BP Unit signals can be degraded by electromagnetic interference. 32 M3815-90001-UG-Eng-revD.qxd 5/1/01 4:20 PM Page 33 BP User Guide Electromagnetic Compatibility Avoiding Electromagnetic Interference Problems Eliminating or moving the source of interference can prevent electro-

magnetic interference. Possible sources of interfering radio frequency radiation are cellular telephones, cordless telephones, or other products that contain radio transmitters. The BP Unit has a Radio Test button that sends a reduced strength test radio signal to the Home Hub, which sounds an audio tone if the test signal is successfully received. This test can be used to determine whether sources of interference are present. These sources can be turned off or moved away to reduce their strength and reduce interference. In addition, the BP Unit and the Home Hub can be placed closer to each other so that the radio transmission from the BP Unit to the Home Hub has less distance to travel and interfering radio signals have less effect. The radio transmission from the BP Unit is repeated periodically so that an intermittent source of interference should only delay, not prevent, reception. 33 M3815-90001-UG-Eng-revD.qxd 5/1/01 4:20 PM Page 34 FCC Regulations This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy. If it is not installed and used in accordance with the instructions, it might 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 mea-

sures:

Re-orient or relocate the Home Hub.

Increase separation between the measurement devices or the Home Hub and the device being interfered with; e.g., the television.

Consult your Health Care Provider. Note: Any changes or modifications to the equipment that are not expressly approved by Agilent could void the users authority to operate this equipment. 34 M3815-90001-UG-Eng-revD.qxd 5/1/01 4:20 PM Page 35 BP User Guide Conclusion Agilent and your Health Care Provider appreciate your efforts to partici-

pate in your home health care plan.
