Notices to Practitioners and Subjects
Electromagnetic Interference (EMI) Advisories
Introduction
The VitalSense Integrated Physiological Monitoring System uses wireless
telemetry to send data over a distance. By nature, wireless devices use an
“open” channel which is shared by other wireless devices which may be
interfered with, or may interfere with the VitalSense system.
Consequently, the customer is advised to carefully consider the
environment in which the VitalSense system will be used. The VitalSense
system was designed for use in general health care and household
environments. It may also be used in research facilities and field research.
The VitalSense system can be used in some military environments, but is
not intended for use in military aircraft or shipboard.
VitalSense sensors should not be ingested or affixed during Mag-
netic Resonance Imaging (MRI). Sensors contain ferro-magnetic
materials.
VitalSense Frequency
The channel frequency for the VitalSense system is 40.68 MHz and the
frequency band is 40.66 – 40.70 MHz. Although this is a seldom-used
band, Mini Mitter recommends that you check the channel frequency of
other wireless devices intended for use in the vicinity of the VitalSense
system. Other wireless devices operating in the frequency band of 40.66 –
40.70 MHz may interfere with, or may be interfered by the VitalSense
system. Generally, the output power of the sensors is extremely low and is
unlikely to interfere with any equipment in the area. It is more likely that
another device operating in the same band will interfere with the
VitalSense system.
EMI Effects on VitalSense System
If the VitalSense system experiences interference, the monitor will no
longer receive intelligible transmissions from the sensors. In Standard
Mode, whenever transmissions from the sensor are missed, an asterisk is
displayed next to the temperature. This asterisk remains until a
transmission is received. The data is updated on average every 15 seconds.
If the display flashes, but the asterisk remains, the sensors are still
experiencing interference. In Medic Mode™, data from a particular sensor
experiencing interference will not be displayed at all. Once the interfering
signal is eliminated, the asterisk displayed in Standard Mode will
disappear, and new data will be displayed in either mode.
viii
EMI Avoidance
The VitalSense system is intended as a short range wireless device. The
maximum distance at which the capsule sensor can be used is 1 m, and the
maximum distance at which the patch can be used is 2 m. If transmissions
appear to be lost, bring the monitor closer to the sensors. Move the system
away from any devices you suspect may be emitting electrical radiation.
The VitalSense system is intended to be an ambulatory system worn on
the body, with the monitor placed at or near the waist. Because of its low
power, it is not recommended for use in electrically noisy environments.
Although protected by filtering, the VitalSense system is susceptible to
frequencies other than the channel band. The VitalSense system has been
tested for RF immunity between 2 MHz and 1800 MHz. Generally, the
system can still be used when the maximum field strength of the
interfering signal is 10 V/m. Table 1.1 lists those frequencies which may
cause interference at levels below 10 V/m.
Table 1.1
Frequencies where RF Immunity is less than 10 V/m
Frequency Dermal Patch RF
Immunity Level Capsule RF
Immunity Level
17 MHz - 26 MHz 7 V/m 3 V/m
56 MHz - 83 MHz 5 V/m 3 V/m

Medical Telemetry Systems
VitalSense has been designed in accordance with the FDA advisory,
“FDA Public Health Advisory: Risk of Electromagnetic Interference with
Medical Telemetry Systems,” July 10, 2000; and in accordance with FDA
Guidance Document, “Wireless Medical Telemetry Risks and
Recommendations.” In regard to those advisories:
•The VitalSense system does not operate in the TV or PLMRS bands
at 174-216 MHz and 450-470 MHz.
•VitalSense does not operate within the frequency bands 26.96-27.28
MHz, utilized by remote control devices.
Electrostatic Discharge Effects on Monitor
The VitalSense Monitor is designed to recover from air discharge
Electrostatic Discharge (ESD) effects of 12 kV or less to any surface of
the monitor. If an ESD discharge of greater than 12 kV is directly applied
to the monitor, it may result in the monitor display momentarily going
blank. If this occurs, the VitalSense Monitor will refresh the monitor
display either when any button is pressed, or if a sensor transmission is
received.
xi

Travel by Commercial Aircraft
Following activation, VitalSense sensors are radio transmitters. The
Dermal Patch sensor has a range up to 2 meters, and the Capsule Sensor
has a range up to 1 meter. The VitalSense Monitor can be a source of radio
interference. They should not be used on commercial aircraft without the
expressed permission of the governing aircraft security agency in
countries of travel and the airline carrier. In the United States, this is the
Transportation Security Administration under the Office of Homeland
Security. Mini Mitter suggests the following:
•Do not activate the sensors until your flight has concluded.
•If you do inadvertently find yourself in the position of having to board
an aircraft with activated sensors, realize you may have to do the
following:
Remove all Dermal Patch Sensors and leave them behind.
Turn off the VitalSense Monitor. If it is in Lockout Mode, remove
the battery. The monitor will retain the data that has been collected.
If you have ingested a Capsule Sensor, it is recommended that you
tell the security screener that you are wearing an ingested medical
device.
It is recommended that you be totally honest with airport security
personnel. Although they are familiar with implanted devices, wireless
thermometers may be unfamiliar to them. Policies regarding medical
devices are typically very accommodating. If there are any questions we

NTRODUCTION
This is an instruction manual for the operation and maintenance of the
VitalSense Integrated Physiological Monitoring System. This wireless
system consists of the following components:
VitalSense
Components •VitalSense Monitor
•Dermal Patch Sensor
•Capsule Sensor
•VitalSense Application Software
•Serial monitor-to-PC interface cable
Once a sensor is activated, it measures and reports the temperature data to
the monitor an average of four times per minute. The temperature data are
time-stamped and recorded in the non-volatile memory.
1-2 Introduction
A Standard Mode VitalSense Monitor can monitor up to ten sensors. In
order to do this, each sensor must be activated by the monitor that will be
recording that specific sensor. During activation, each sensor and the
monitor are synchronized.
In optional Medic Mode™, an unlimited number of sensors may be
operationally verified and the temperature recorded with a time stamp.
Getting Started - THIS MUST HAPPEN FIRST
The following must occur before a new data collection session can
begin:
•Monitor clock must be set - (from monitor front panel or the host PC)
•Erase data memory - (from monitor front panel or the host PC)
•Logging must be turned on - (from monitor front panel or the host PC)
•Sensor(s) must be activated - (from the monitor only)
See “ Monitor Setup for Data Collection ” on page2-4.
Monitor
The VitalSense Monitor is a central element in the VitalSense system. It
serves to activate the sensors, track and record data from the sensors, and
provide an interface to a computer.
Sensor activation is a key event in the operation of VitalSense. It is used to
synchronize the monitor with each sensor. Once activated, the monitor can
display the incoming data in real-time and at the same time log the data to
the non-volatile memory for future transfer to a computer.
Sensors
VitalSense sensors are activated by the VitalSense Monitor. Once
activated, a sensor will begin its monitoring assignment, and will continue
to function until the battery expires (approximately 240 hours), the sensor
is removed from the sensor schedule, or the sensor is disposed.
Each sensor is given an identity number at the factory, along with
temperature calibration data. During activation, these data are
automatically retrieved from the sensor and stored in the monitor memory.
All sensors are activated using essentially the same process:
•A specific optical signal from the monitor activates the sensor.
•By radio, the sensor transfers its identification and calibration data to
the monitor.
Following activation, the sensor is either swallowed (Capsule Sensor), or
affixed to the body (Dermal Patch Sensor). The activation process is
identical for each sensor. Sensors are single-use and cannot be de-
activated. Additional sensors may be ordered from Mini Mitter Company,
Inc. See “ Contacting Mini Mitter Technical Support ” on page-v.
1-3
Tracking
Tracking is a term used in this manual which refers to the synchronization
of the VitalSense Monitor and the sensors.
In order to preserve battery power of the VitalSense Monitor and conserve
the power of the sensors, the sensors are designed to transmit according to
a pre-determined schedule. Both the sensor and the monitor which
activated it have this schedule. As a result, the monitor only “listens” for a
specific sensor for a short period during the expected transmission time. It
is through the activation process and the periodic reception of these
transmissions that the monitor remains synchronized with the sensor
transmission schedule. The monitor quite literally “tracks” the minor
variations between the two clock sources at each transmission.
Firmware
VitalSense firmware is operational information that is programmed into
the VitalSense Monitor non-volatile memory. When calling Mini Mitter
Technical Support, the version number of this firmware can be very
helpful. To find the firmware version using the VitalSense Application
Program, see “ Firmware Version ” on page3-21.
Software
Installed, the VitalSense Application Software converts a PC to “host
status” for the VitalSense Application Program, allowing setup of select
monitor functions, real-time monitoring of data, and retrieval of data
which have been stored on the monitor.
Installation of the VitalSense Application Software can be found under
“ Installation of Software ” on page3-3.
Calibration
VitalSense transmitter/sensors do not require calibration prior to use.
EMI and ESD Susceptibility
It is recommended you read the advisories concerning EMI and ESD.
They begin on page-vii.

VitalSense Monitor - Description
The VitalSense Monitor is a splash-resistant, battery-operated receiver
and logger. It activates the sensor via an optical beam, receives data from
the sensor by radio, records data in a non-volatile memory, and facilitates
transferring the data to a computer via a cable.

2-4 Monitor Operation and Sensor Activation
Monitor Setup for Data Collection
Before data collection can begin, the monitor must be set up, or
configured. All configuring can be done from the monitor front panel, and
some configuration functions can be done from the host PC. This section
will cover monitor front panel operations.
There are three requirements that may have to be accomplished before the
monitor will collect data:
•“ Erase Data Memory ” on page2-27
•“ Adjusting the Time/Date ” on page2-20
•“ Activating Sensors Using the VitalSense Monitor ” on page2-7
Some of these requirements may not be necessary, e.g., if you have
configured VitalSense previously, erased the memory, or if you have
already set the time.
Time and Date Time and date must be set carefully. VitalSense data are collected with
UTC (Universal Coordinated Time) as a reference. However, the monitor
can display Local time as well as UTC.
If the UTC or Local times, and the UTC offset are entered correctly,
VitalSense can compensate for Standard and Daylight time changes (US
only).
If adjusting the time from the host PC, the monitor may automatically be
set to the same time as your PC clock.
CAUTION! You cannot change the UTC time or date with sensors
on-line. (UTC offset and Daylight Saving Time compensation are
allowed.)
A note on UTC UTC is based on precise atomic clocks, shortwave time signals, and
satellites. This insures that there is a reliable, accurate standard for
scientific and navigation purposes.
The difference between local time and UTC is called the UTC offset.
For detailed information on UTC, see “ Universal Coordinated Time ” on
pageB-1.

2-10 Monitor Operation and Sensor Activation
Administration
Both the Capsule Sensor and the Dermal Patch contain ferromag-
netic materials incompatible with MRI (magnetic resonance imag-
ing) and should not be worn nor ingested if an MRI is planned. Any
subject ingesting or affixing the above sensors is to wear an MRI
Warning wrist band (supplied with each sensor) as long as the sen-
sors are in place.
Dermal Patch Sensor
1Remove excess hair from the area in which the sensor will be mounted.
2Prepare the skin by cleaning with an alcohol-moistened wipe.
3Following successful activation, use the tab to peel away the protective
layer.
4Affix the Dermal Patch Sensor to the skin.
5Affix an MRI Warning wrist band (supplied) to the subject with
instructions that it is to be worn as long as the Dermal Patch is in place.
Keep the VitalSense Monitor within 2 meters of your body.
NOTE: Avoid the use of lotions and emollients in the area of the
Dermal Patch Sensor. Their uses may cause the adhesive to loosen.
Capsule Sensor
Do not chew. There are metal components inside the capsule. Swal-
low whole with liquid.
1Following successful activation, swallow the Capsule Sensor with
approximately 8-ounces of water, juice, or soft drink.
2Keep the VitalSense Monitor within 1 meter of your body.
3Affix an MRI Warning wrist band (supplied) to the subject with
instructions that it is to be worn until the Capsule Sensor has been
expelled.

Sensor Does Not Activate
Failure to activate immediately
If the sensor does not activate within a few seconds, it may be waiting for
a transmission from a previously activated sensor. Hold the sensor in
place. Once the transmission has been received, the monitor will activate
the new sensor.
NOTE: As more sensors are brought on-line, the monitor may need
to wait for longer periods.
Activation delay notice
Failure to activate
If a sensor fails to activate, you will be prompted. There may be several
reasons for non-activation.
Sensor activation failed
•Wait approximately 5 seconds and try again.
•Check Data Views to verify that there is no sensor activation.
•Check that the sensor lens is aligned properly with the activation port.
•Attempt to re-try at least 3 times. If still not activated, return the sensor
to Mini Mitter for analysis.
2-12 Monitor Operation and Sensor Activation
Duplicate sensor
The sensor will not activate if the identification number of the sensor is
identical to one already in the monitor schedule.
