WARNING
USE
The EME Guard is an alarm dosimeter designed for use as surveillance equipment of
people who could be exposed to high levels of electromagnetic field. It provides NO
protection in any way against possible exposure. The EME Guard is purely a monitoring
device.
The use of this device complies with different international recommendations concerning
the exposure of workers to electromagnetic fields and notably the European directive
2004/40/EC.
The EME Guard can be worn on a belt or strapped across the body and has been designed
to fulfil the following requirements:
-detect the presence of electromagnetic fields,
-alert the user when predetermined levels have been exceeded,
-record the field levels to which the worker has been continually exposed so that they
can be downloaded, analysed and stored.
The thresholds above which the alarms are required to be triggered are to be defined and
configured by the person responsible for parameterization of the device. All legal norms
and directives in force relative to the exposure of individuals to electromagnetic fields
must be respected.
The EME Guard Analysis software provided with the dosimeter enables the alarms to be
configured and the data to be recorded.
The EME Guard enables the field measurements to be recorded at a period and duration
configured by the user. It also allows the downloading and display of field measurements.
This device has left our premises in perfect working order. The following safety measures
must be respected in order to guarantee accurate results.
This device must only be used for the applications for which it has been designed.
It is essential that only people authorized by SATIMO should carry out repairs and
maintenance of the device.
Before use make sure that the batteries are sufficiently charged.

-respect the safety measures stipulated by the equipment operator or original
equipment manufacturer.
-respect the operating instructions and recommendations for equipment which
generates, emits or uses electromagnetic energy.
-never expose the field monitor to high intensity electric fields (for example inside a
microwave oven). Such exposure could damage the device.
-secondary sources (reflective objects such as metal fences) can also locally
increase the field intensity.
-the intensity of the electromagnetic field can be under-evaluated if the wearer’s
body comes between the field source and the measuring device.
-the data provided in the technical characteristics will only be accurate if the tests
are carried out in optimal conditions, in the absence of all interference radiation.
-Measuring devices can under-evaluate the intensity of pulsating signals.
-Fields composed of a spectrum situated outside the frequency band covered by the
device can be incorrectly evaluated and can be under- or over-evaluated.

2OPERATING THE DOSIMETER
2.1 PARAMETERS FOR USE
The different configurable parameters and thus the EME Guard Dosimeter can be adapted
to suit the needs of each user, through the EME Guard Analysis Software.
How to configure these parameters is explained in detail in the paragraph 3.3
CONFIGURING THE DOSIMETER.
2.1.1 Reference Threshold – Visual Alarms
The reference threshold is used by the device to determine the visual alarms.
The measurements displayed by the 4 visual alarm lights are the instant field
value expressed as a percentage of the chosen reference threshold.
2.1.2 Audio Alarm and Vibrating Alarm
The EME Guard has also two additional independent alarms (audio alarm and vibrating
alarm).
Three operating modes are possible for both of these alarms. The trigger threshold of
these alarms is expressed directly in V/m.
The alarms are triggered if the measurement taken is superior to the configured threshold
without reference to a percentage to the reference threshold which is used only by the
visual alarms.

2.1.3 Recording Measurements
The EME Guard has a measurement recording function which can be activated or de-
activated with the help of the EME Guard Analysis V2.0 Software
The non-volatile internal memory enables a maximum number of 30,000 measurement
points (each measurement is time/date-stamped).
Measurement recording depends on the period and duration configured using the EME
Guard Analysis V2.0 Software.
This function enables the study of the level of exposure of the user to electric fields over a
predetermined period of time.
2.2 STARTING PROCEDURE
Press the ON / OFF button.
The ON light is activated.
Maintain pressure for approximately one second until the ON light switches off and the
BATT. light comes on.
The device will then run an auto-test sequence enabling the user to check that all display
and alarm functions are operational.
2.2.1 Auto-test sequence of lights and alarms
The ON and BATT. lights are activated simultaneously for approximately 0.2 seconds.
The 25%, 50%, 75% and 100% lights are activated successively in this order then de-
activated in reverse order.
Each threshold reference light (20 V/m, 40 V/m, 60 V/m, 80 V/m, 100 V/m and 140
V/m lights in this order) is activated for approximately 0.1 seconds.
The audio alarm is activated for approximately 0.2 seconds.
The vibrating alarm is activated for approximately 0.2 seconds.
If one of these elements is not activated during the auto-test it is probably
defective.

13 / 37
2.2.2 Estimation of Remaining Autonomy
The field level lights (25%, 50%, 75% and 100% lights ) enable the display of an
estimation of remaining power autonomy.
Display of Estimated Remaining Electric Autonomy
>72 hours >54 hours
>36 hours >18 hours
<18 hours
If the battery power is insufficient
to give accurate readings, the
BATT. light flashes. (see 2.3 Low
Battery)
2.2.3 Starting Measurements
The light corresponding to the reference threshold defined by the user is activated.
The ON light remains on for approximately 3 seconds (the internal function parameters
are activated.)
Measurements are then taken every second. The ON light flashes every time a
measurement is taken.
The different alarms (visual, audio, vibrating) are updated upon each measurement (every
second). Recordings can be made at a different rhythm.
2.3 LOW BATTERY
When the battery is too low to give accurate readings, the measurements stop
automatically and the BATT. light flashes indicating that the battery must be recharged.
Pushing the ON / OFF button will stop the device.
Connecting the device to a computer (USB) will stop the device
Note 1 : If the battery continues to weaken, the BATT. light will switch off automatically
when the energy level is insufficient to power the device.

14 / 37
2.4 STOPPING THE DEVICE
The dosimeter can be switched off at any moment by pressing the ON / OFF button. The
button must be depressed for one or two seconds until the ON light switches off. This is so
that if the button is pressed accidentally the device will not be switched off.
3 audio beeps are emitted, indicating that the device is switching off.
If switched off in mid measurement cycle, the cycle will pick up where it left off when the
dosimeter is switched back on. This downtime will not be recorded in the total time of the
measurement recording cycle.
