Introduction
WELCOME
Welcome to Philips Telemonitoring
Services.
This Pulse Oximeter Instructions for
Use explains how to use the Pulse
Oximeter to measure your blood
oxygen level (%SpO2) and pulse
rate from the comfort and
convenience of your home. It also
explains how to maintain, clean,
and troubleshoot the Pulse
Oximeter and gives a number of
safety precautions you should
follow to assure safe, reliable and
accurate measurements.
In only a few minutes every day
you can provide these
measurements to your healthcare
provider so that he/she can make
better decisions about your care. In
this way, you are providing
information that can help improve
your health care and quality of life.
How the System Works
With this system, the Pulse
Oximeter measurements are
immediately sent to your Home
Hub or TeleStation, which then
automatically transmits them over
your telephone line to your
healthcare provider’s computer.
While the system uses your
telephone to transmit the
measurement, feel free to talk on
you phone at any time -- the system
is “smart” enough to know when
the phone line is open. It will wait
and then send the information after
you hang up.
Keeping the System
Working
If at any time you suspect
something is wrong with the Pulse
Oximeter or any part of the
Telemonitoring System,
immediately contact your
healthcare provider. Philips will
replace any defective device. You
can also cross-check your results
with another Pulse Oximeter if
additional measurement devices of
the same type are available to you.
Thank You!
Thank you for taking an active role
in your home healthcare plan.
Philips and your healthcare
provider applaud your efforts to
actively participate in you health
care plan.

Pulse Oximeter Components
The Pulse Oximeter is a plastic
display case with a finger-clip
sensor attached to it. The front of
the case has the following elements,
as shown in the figure below. The
rear of the case has a compartment
for batteries that power the device.
Display: an LED display window
shows the blood oxygen level
(%SpO2) and pulse rate (in beats
per minute) measured from the end
of your finger. LEDs below the
display window light to indicate
which measurement is being
displayed -- %SpO2 or pulse.
START button: pushing this
button causes the Pulse Oximeter
to begin taking a measurement.
Radio Test button: this
button is used to test the
transmission of measurements
from the Pulse Oximeter to the
Home Hub or TeleStation.
Finger-clip sensor: This sensor
is used to measure your blood
oxygen level and pulse rate. The
sensor is clipped on the end of one
of your fingers.
The Finger-clip contains an LED
light source that shines light on
your finger. Light transmitted
through the blood in your finger is
received by a photo sensitive
element and electronics in the
display case uses the transmitted
light to determine your blood
oxygen level and pulse rate.

Hub or TeleStation with your
hand resting on a flat surface and
the Pulse Oximeter in front of
you.
2. Open the sensor and fully insert
your finger (index, middle, or
ring, but not your thumb) until
the end of your finger reaches the
finger stop. The cable should
extend over your finger toward
your wrist as shown in the figure.
3. Sit comfortably with your hand
resting on the surface so that it
can remain still.
4. Press the START button and
hold your hand still during the
measurement.

Notes:
Use the same finger each time
you make a measurement
unless your health care
provider instructs otherwise.
Do not use the sensor on a
finger that has chronic poor
circulation or is injured.
Avoid wearing dark fingernail
polish (particularly blues and
blacks) that may reduce light
transmission and affect
measurement accuracy.
Avoid using the sensor in
sunlight or bright lights.
Do not use the Pulse Oximeter
with the battery door open
The measurement process is as
follows:
- Dashes move across the display
during measurement.
- A double beep sounds after a
few seconds indicating that the
measurement is complete.
- A tick sounds as the % SpO2
measurement displays and the
yellow light next to % SpO2
illuminates.
- A tock sounds as the pulse rate
displays and the green light next
to pulse illuminates.
- The tick-tock sequence repeats
several times and then turns off.
Note: If the measurement was not
made, a long beep sounds
and displays.
Warm your hand or use a different
finger and try again.

Electromagnetic Compatibility
Electromagnetic
Compatibility
Electromagnetic compatibility
(EMC) is the ability of equipment
to function satisfactorily in the
presence of radio frequency (RF)
energy from devices such as
cordless and cellular telephones or
other RF transmitting equipment.
The Pulse Oximeter was tested
according to the international safety
standards for EMC of medical
electrical equipment. See the
Manufacturer’s Declaration for
details.
EMC Testing
The M3814 Pulse Oximeter was
subjected to both international
standard and Philips proprietary
tests. During the testing to the
requirements of the medical safety
standard IEC/EN 60601-1-2 (first
edition), some anomalies were
observed as described below. If you
observe any abnormal operation of
the devices, please see Avoiding
Electromagnetic Interference
Problems later in this section.
The M3814A Pulse Oximeter may
also exhibit sensitivity to
electrostatic discharges as low as
+ x.xx kV to nearby objects or
interconnecting cables.
Electrostatic sensitivity does not
put critical patient data at risk and
normal operation is restored after
approximately xxx minutes without
user interaction. Measurements
stored in the M3814A are retrieved
following device recovery.

* Interference levels are measured in Volts per meter. A cellular telephone
operating at a typical transmitting power of 0.1 watts will produce an interference
level of 1 Volt per meter at a distance of 1 meter from the cellular telephone’s
antenna. Please see Avoiding Electromagnetic Interference Problems later
in this section.
15
Avoiding Electromagnetic
Interference Problems
Possible sources of interfering
radio frequency energy are cellular
telephones, cordless telephones,
and other products containing
radio transmitters.
The M3814A has a Radio Test
button that sends a reduced
strength radio test signal to the
M3184A Home Hub or the
M3812B TeleStation and 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
interference to your Pulse
Oximeter.
In addition, the Pulse Oximeter and
M3812A Home Hub or M3812B
TeleStation can be placed closer to
each other so that the radio
transmission from the Pulse
Oximeter to the M3812A Home
Hub or M3812B TeleStation has
less distance to travel and
interfering radio signals have less
effect. The radio transmissions
from the Pulse Oximeter are
repeated periodically, so an
intermittent source of interference
should only delay reception.
Recommended separation distances between portable and mobile RF
communications equipment and the Philips Telemonitoring System
The Philips Telemonitoring System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the Philips Telemonitoring System can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the Philips Telemonitoring System
as recommended below, according to maximum output power of the
communications equipment.

16
FCC Regulations
The M3814A Pulse Oximeter 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 provide
reasonable protection against
harmful interference in a residential
installation. The M3814A Pulse
Oximeter generates, uses, and can
radiate radio frequency energy. If
not installed and used according to
instructions, it may interfere with
radio communications. However,
there is no guarantee that
interference will not occur if the
equipment is properly installed.
If the M3814A Pulse Oximeter
causes 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 it by:
relocating the Home Hub or
TeleStation,
increasing the separation
between the Pulse Oximeter
or the Home Hub or
TeleStation and the device
being interfered with, for
example, a TV,
consulting your healthcare
provider.
Note: Any changes or
modifications to the equipment not
expressly approved by Philips could
void the user’s authority to operate
it.
