over your arm. Place your hand into the cuff.
3. Slide the cuff up your forearm.
4. As you slide the cuff on, position the cuff so that the bottom of
the cuff is on your upper arm and about one inch above the
elbow crease; make sure that the air hose dangles
on the inside of your arm.
5. Pull on the cuff end to tighten it. The cuff does not have to be
pulled very tight. For comfort, you can leave room for one fin-
ger to fit under the cuff.
6. Fold the cuff end back over the metal D-ring, and fasten the
cuff end to the Velcro®closure.
7. Press the START/STOP button. Sit still and do not move your
arm during the measurement. If you want to stop the measure-
ment at any time, press the START/STOP button. Wait 15 min-
utes before taking your blood pressure again.

Welcome to Agilent Technologies’ Interactive Healthcare Services. Your
Health Care Provider has enrolled you in a progressive program to mea-
sure, transmit, and review your vital signs on a daily basis. This pro-
gram’s approach will help you and your provider make better informed
decisions about your care.
Your patient measurement set—which may include a Scale, Blood
Pressure Unit, Rhythm Strip Recorder, and Home Hub—is designed to
let you quickly and easily take your vital signs. The data you collect in
a few minutes each day are automatically transferred via the Agilent
Home Hub, using your existing phone line, to your Health Care
Provider’s computer system. The Home Hub is smart enough to know
when you’re not on the phone, and that’s when it will make the data
transfer. You do not need to do anything. Feel free to use the phone at
any time. The Home Hub also recognizes if the connection was inter-
rupted and will automatically re-transmit stored information later.
If any of the devices in your patient measurement set is not functioning
properly, please advise your Health Care Provider and Agilent will
repair or replace the device.
As a user of Interactive Healthcare Services, you are taking an active
role in providing your Health Care Provider with accurate, relevant, and
timely information—information we expect will go a long way toward
improving your quality of life.
The Blood Pressure Unit User Guide explains how you can measure your
blood pressure and pulse rate from the convenience and comfort of your
own home. This guide provides you easy-to-understand information about
operation and maintenance. Agilent and your Health Care Provider appre-
ciate your efforts to actively participate in your home health care plan.

Electromagnetic Compatibility
The electromagnetic compatibility (EMC) validation of the M3815A
Blood Pressure Unit included testing performed according to the inter-
national standard for EMC with medical devices. See the
Manufacturer’s 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.

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.
