chapter 1 the telemetry system
The telemetry system from emka TECHNOLOGIES is intended for use in preclinical
research, primarily toxicology and safety pharmacology studies.
It is a non-invasive, or external, system that acquires biological data from large
subjects such as dogs and non-human primates then transmits these data
wirelessly to a data acquisition station.
The different components of the telemetry system are shown in figure 1. This is a
standard set-up consisting of one antenna per cage and a small number of
subjects (to aid understanding, only key components and connections are shown).
figure 1 a standard telemetry system installed by emka TECHNOLOGIES
The different components of a standard telemetry system are as follows:
emkaPACK transmitter
The emkaPACK transmitter is a compact and durable unit that fits neatly into a
jacket pocket on the back of the subject. Each emkaPACK transmitter collects,
conditions, converts (to digital), and transmits physiological signals on a specific
frequency channel.
antenna
receives the transmitted signals, and is connected to the receiver module, directly
or via an antenna network.
receiver mainframe
houses and powers the receiver modules
emkaPACK receiver module
Each is tuned to a specific frequency channel, and forms a pair with a specific
emkaPACK transmitter. The modules slot inside the receiver mainframe.
versatile antenna adapter (VAA) (not shown on figure)
One or more VAAs combine to form an antenna network. Their role is to combine
and/or split the radio signal going from one or more antennas to one or more
the telemetry system
______________________________________________________________________________________________________________________________
emka TECHNOLOGIES page 11
receiver modules. This allows greater flexibility when planning experiments (for
example, with a VAA, a particular emkaPACK can be used in different pens in
different recording sessions).
workstation
every setup contains at least one workstation equipped with a data acquisition card
and software for acquiring, analyzing and storing data. In figure above, iox2 is
used for acquisition, analysis and storage. For ecg data, advanced analysis can be
carried out with ecgAUTO software.

emka TECHNOLOGIES page 12
chapter 2 emkaPACK transmitter
The emkaPACK transmitter performs collection, conditioning (including
amplification), analog-to-digital conversion, and transmission of ecg and activity.
It runs on two AA/R6 alkaline batteries providing continuous acquisition of 7-lead
ecg and activity data for an average of 80 hours.
With regard to battery choice:
• it is strongly recommended to avoid high-power batteries (see chapter 9).
• it is preferable to use single-use (disposable) rather than rechargeable
batteries (see FAQ "can I use rechargeable batteries?" in chapter 7).
The emkaPACK transmitter does not have a power switch. It is automatically
switched on and off when the ecg cable is connected and disconnected.

2.1.3 ecg connector
The ecg cable is connected to the ecgLEADS connector (figure 4).
2.1.4 primary connectors
These connectors are used to connect to modules for the acquisition of
physiological signals other than ecg and activity.
figure 4 ecg connector and primary connectors
2.1.5 secondary connectors
These connectors connect to modules for the acquisition of physiological signals
other than ecg and activity (figure 5).
These connectors are not fitted on the emkaPACK as standard, because they are
only for use with modules by emka TECHNOLOGIES. Nevertheless, markings are
provided on the emkaPACK for customers who purchase the modules (figure 5).
(In this case, the connectors may be fitted by customers themselves or by
emka TECHNOLOGIES.)

2.2 acquired parameters
2.2.1 ecg
The emkaPACK is used to obtain ecg data from large animals, such as dogs,
primates and pigs. Three configurations are possible
• 1-lead ecg, using a 3-wire ecg cable
• 6-lead ecg, using a 4-wire ecg cable, for obtaining the standard leads,
namely three Einthoven bipolar leads (I, II, III) and three Goldberger unipolar
leads (aVR, aVL, aVF)
• 7-lead ecg, using a 5-wire ecg cable - 6-lead ecg as above plus one
unipolar chest lead (Wilson lead)
The colors used for the different wires are those defined by standards (Table 1).

3.1 what is supplied
• ecg cable containing 3, 4 or 5 wires, as requested by the customer.
Electrodes provided with 4-and 5-wire cables are color coded in
accordance with IEC standards (on request, emka TECHNOLOGIES will supply
cable color coded according to AAMI standards).
• electrode connectors (Comepa) - both banana and clip connectors are
supplied (figure 7). The clip connector is inserted around the banana
connector. Therefore, simply remove the clip connector if you want to use
the banana connectors.

3.2 setting up the emkaPACK transmitter
The setup involves calibration only.
3.2.1 calibration of ecg signal
The ecg measurement chain is factory calibrated and temperature compensated.
You simply enter the two pairs of calibration values directly into your data
acquisition software:
low high
Physical value (mV) -5 5
Output signal amplitude (V) -5 5
table 2 calibration values for ecg signal
If you are using iox2, this 'manual calibration' is done in 'two-points calibration
(manual)'.
To perform calibration, you can also use a device that simulates ecg output. You
may use the ecg calibrator from emka TECHNOLOGIES for this purpose (sold
separately).

chapter 4 running sessions
This chapter describes how to run a session for the acquisition of 7-lead ecg and
activity in dogs.
It is assumed that the telemetry setup also includes iox2 (a software application for
acquiring, analyzing and storing data) and you are using clothing from Lomir
(custom-designed for the emkaPACK).
4.1.1 requirements
• ecg cable (supplied)
• banana and clip connectors (supplied)
• adhesive electrodes (available from emka TECHNOLOGIES separately)
• clippers
• gauze sponge
• alcohol for disinfecting the skin
• white tape
• undershirt
• jacket
• self-adherent bandaging (optional), such as VetrapTM (3M, Bracknell, Berks,
United Kingdom)
4.1.2 running a session
1. Insert new batteries.
subject preparation - place the electrodes
There are two possible ecg configurations.
standard configuration
1. Shave the skin on the underside of the subject in five different areas as
follows:
• two circles of 5 cm diameter below the left front leg and the right front leg
(LA and RA electrodes)
• two circles of 5 cm diameter mid-way between the front and rear legs, on
the left side and the right side (LL and RL electrodes)
• one circle of 5 cm diameter 7 cm below the front left electrode (V
electrode), i.e. under the heart
2. Wipe each area with gauze sponge and alcohol and allow to air dry.
3. Connect the electrodes to the wires of the ecg cable.
4. Place the adhesive electrodes on the bare skin, at the correct site (figure 8).
Press around the edge of the electrode but not in the centre.
running sessions

emka TECHNOLOGIES page 19
figure 8 standard placement of electrodes
alternative configuration
Experience has shown that this configuration can also provide high-quality ecg
signals, notably in beagles. The placement of electrodes for 6-lead ecg (shown in
figure 9, AAMI colours) is adapted to the position of the heart (more central within
the chest cavity), with the current flows crossing in the subject’s chest (figure 10).
All the electrodes should be aligned along an imaginary circle drawn around the
subject's chest and be located away from its normal range of movement.

______________________________________________________________________________________________________________________________
emka TECHNOLOGIES page 20
subject preparation - dress the subject
5. Secure the wires in position with the undershirt. As an alternative or if the
undershirt is not sufficient, use white tape and bandaging (figure 11). The
bandaging must not be too tight as this will impair the animal's breathing.
figure 11 placing bandaging around electrodes and wires
6. Place the jacket around the subject.
7. Place the emkaPACK transmitter in the jacket pocket.
8. Ensure that there are no loose wires hanging out, as these are liable to be
chewed or to catch on objects. The subject is ready (figure 12).
figure 12 emkaPACK transmitter in place
The procedure is the same for other ecg configurations (such as 6-lead ecg) with
steps 1 to 4 modified accordingly. figure 13 shows electrode placement for
obtaining 1-lead ecg (for lead II ).
important! all the wires of the ecg cable must be connected to the subject, even if
you are not using them (for example, if you wish to acquire 1-lead ecg with a 5-wire
cable). Otherwise, the signal will be inaccurate. ecg cable can be ordered from
emka TECHNOLOGIES.

note: the emkaPACK transmitter can be used to obtain ecg data from other large
animals, such as primates and pigs.
power up
Plug the ecg cable into the ecgLEADS connector to turn on the emkaPACK
transmitter. It then performs a boot procedure. During this procedure, which only
takes a few seconds, the led goes from off to solid green (i.e. not flashing). After
successful boot-up, the led simply goes off.
If the LED does not go on or goes solid red, there is a potential problem with the
emkaPACK transmitter. If this happens, switch off the emkaPACK transmitter (by
disconnecting the ecg cable), check the connections and batteries, then switch it
on again. If the problem persists, please contact emka TECHNOLOGIES (see
'Technical support' chapter).
recording session
No particular action is required during recording sessions.
If the battery charge falls below a certain level, the 'low battery' led lights up on the
corresponding receiver module.
4.1.3 after sessions
At the end of the experiment, disconnect the ecg cable from the emkaPACK
transmitter to switch off the power.
The emkaPACK transmitter should be stored in a cool dry place. Keep it away from
sunlight and other sources of heat. Keep it away from sources of magnetism.
If you will not be using the emkaPACK transmitter for some time, remove the
batteries.

chapter 5 maintenance
For accurate data, the calibration of the telemetry system must be verified on a
regular basis. At installation, emka TECHNOLOGIES provides a calibration certificate
valid for one year. Certificate renewal (verification or recalibration) is performed as
part of maintenance contracts.
Calibration should be performed as often as necessary. In practice, the frequency
of calibration is imposed by internal regulations or is indicated in certain situations,
e.g. exposure to highly variable temperature, humidity, shock etc.
Check the cables and connectors regularly.
If you will not be using the emkaPACK transmitter for some time, remove the
batteries.

chapter 7 frequently asked questions
7.1 emkaPACK transmitter
can I use the emkaPACK transmitter for eeg measurements?
Each type of bioelectric potential has a characteristic amplitude, frequency, signal-
noise ratio, etc and requires specially designed components. Currently, emkaPACK
telemetry system is designed to measure ecg only. However please let us know if
you are interested in using emkaPACK transmitter for measuring other
biopotentials. Our aim is to satisfy our customers' requirements.
can I use rechargeable batteries?
Yes, but it is recommended to use single-use batteries to reduce the risk and the
duration of recording gaps during experimental sessions. This is because:
• single-use batteries generally provide current for longer than fully-charged
rechargeable batteries.
• single-use batteries generally have a more gradual discharge curve. This
means that they will reach full discharge 3-4 hours after the 'low-battery'
warning appears (versus 10-15 minutes with most rechargeable batteries).
Please check the website www.emka.fr (in English) to see the latest options. If you
cannot find the product you need for your experiments, please contact us.
is there a help-line?
The answers to most technical issues are contained within this user manual, in
particular, the 'troubleshooting' and 'frequently asked questions' chapters.
If you cannot find a solution in this manual, you may:
• check the website at www.emka.fr (in English)
o products >> software
o applications >> telemetry
o services >> technical support
o services >> FAQs
• contact emka TECHNOLOGIES (see 'technical support' chapter)
• fax back the Support Form in the 'customer feedback' chapter
7.2 ecg
how often do I have to calibrate the ecg module?
Generally, we recommend that users perform calibration with a device that
simulates ecg signals (e.g. ecg calibrator from emka TECHNOLOGIES) at least once a
month. More frequent calibration may be imposed by internal regulations or
indicated in certain situations, e.g. if the emkaPACK transmitter is subject to highly
variable environmental conditions (temperature, humidity, shock etc).
frequently asked questions
______________________________________________________________________________________________________________________________
emka TECHNOLOGIES page 25
what type of ecg data can I acquire using the emkaPACK transmitter?
As part of a telemetry set-up, emkaPACK transmitter may be used for acquiring
• 1-lead ecg
• 6-lead ecg (3 Einthoven bipolar, 3 Goldberger unipolar)
• 7 lead ecg (3 Einthoven bipolar, 3 Goldberger unipolar, 1 unipolar chest lead)
is it possible to change ecg configuration, e.g. from 6-lead ecg to 7-lead ecg ?
Yes, it is possible to change ecg configuration. However, the system must be
adapted by using appropriate cable and reconfiguring emkaPACK transmitter
internal software (this is done by emka TECHNOLOGIES).
Correct cable and reconfiguration are particularly important if you decide to 'down-
grade' ecg configuration (e.g. 7-lead to 6-lead, or 6-lead to 1-lead). If the
appropriate cable is not used, unused electrodes may cause interference. To
ensure accurate signals, every wire of the ecg cable must be connected to the
subject, regardless of whether its signal will be acquired.
can I make eeg measurements using emkaPACK transmitter?
Currently this is not possible. However please let us know if you are interested in
using emkaPACK transmitter for this purpose. Our aim is to satisfy our customers'
requirements.
7.3 activity
how often do I have to calibrate the activity option?
The activity option is factory calibrated; the accelerometer is designed to provide
the same voltage output for a given activity level over time.
You only need to enter pairs of calibration values (voltage and physical quantity)
directly into your data acquisition software. This 'manual calibration' therefore is not
a full calibration because you type in the quantity rather than physically apply it.

- are the batteries the right way?
- have the batteries run out?
Æ Insufficient transmission range
Under normal conditions, the settings of each emkaPACK transmitter should ensure
continuous coverage, wherever the subject is located
there are no signals from any of the emkaPACK transmitters
Possible causes and solutions:
There is no power supply in the receiver mainframe:
Æ Check the power supply module in the receiver mainframe (the led should be
green): Has the fuse blown? Is the power switched on?
there is no physiological signal
Æ Check the connections.
Æ Check that the electrodes connectors have not become disconnected.
the ecg signal is noisy
Æ Check that all wires are connected to the electrodes.
Æ Check that the electrodes are properly stuck to the subject

chapter 9 recommendations
emka TECHNOLOGIES strongly recommends the use of DURACELL
PROCELL AA/LR6 2700 mAh alkaline batteries.
After extensive testing, we found DURACELL PROCELL batteries to be reliable as
well as powerful enough to run emkaPACK for 80 hours when transmitting
information for 7-lead ecg and activity. These batteries are reasonably priced
(around EUR 0.35 or US$ 0.50 each).
Other batteries exist, some of which have a higher energy capacity. For example,
the ENERGIZER ULTIMATE LITHIUM battery has close to twice the energy of a
DURACELL PROCELL. Although their cost is disproportionately higher, some
customers may find them attractive because of their high energy content.
However, we strongly recommend against the use of high-power
batteries to run emkaPACK transmitters; this recommendation is based on the
following facts:
• emkaPACK is powered by two 1.5V batteries running in series, providing a total
of 3V.
• emkaPACK is fitted with an electronics module that provides its key
components a stable 3V power supply even when available battery voltage
drops below the nominal 3V value (as occurs towards the end of battery life).
• emkaPACK does not have an equivalent feature that stabilizes voltage at 3V
when batteries provide a total voltage above 3V.
• high-power batteries usually provide voltage well above 1.5V (typically up to
1.8V), and their voltage remains above 1.5V through most of their life span.
• running emkaPACK with voltage above its nominal 3V has undesirable effects
on the amplitude of the transmitted signal. For example, going from a voltage of
3V to 3.6V causes a decrease of around 15% in the output amplitude of ecg or
activity.
To avoid difficulties and inconsistencies between calibration and
measurements, all customers are advised to use alkaline DURACELL
PROCELL or equivalent batteries.
These recommendations should not present a problem for the majority of our
customers. However, if you believe that the recommended batteries will not have
sufficient power, please contact emka TECHNOLOGIES SA (France) for advice on
how to proceed and/or to find a solution.
Future versions of emkaPACK transmitters will be designed to accept high-power
batteries without any undesirable effects on signal amplitude.
