3.6 Disposal of electronic waste
Electrical and electronic equipment (EEE) contains materials, components
and substances that may be hazardous and present a risk to human health
and the environment when waste electrical and electronic equipment (WEEE)
is not handled correctly.
Equipment marked with the below crossed-out wheeled bin is electrical and
electronic equipment. The crossed-out wheeled bin symbol indicates that
waste electrical and electronic equipment should not be discarded together
with unseparated household waste, but must be collected separately.
For this purpose all local authorities have established collection schemes
under which residents can dispose waste electrical and electronic equipment
at a recycling centre or other collection points, or WEEE will be collected di-
rectly from households. More detailed information is available from the techni-
cal administration of the relevant local authority.

Introduction
4
The FLIR Si124 is a standalone system for acoustic image measurements
and signal analysis. As a standalone system, no additional equipment is
needed for basic usage of the device.
The FLIR Si124 uses 124 microphones to form a very precise acoustic image
in the desired direction. This acoustic image is transposed in real-time on top
of a digital camera picture, which allows the user to accurately see from which
directions sound is arriving to the camera. Interesting sound sources can then
be separated from background noise and saved for deeper analysis and prob-
lem classification, using the FLIR Acoustic Camera Viewer service.
The FLIR Si124 is a lot more sensitive and accurate than the human ear,
which means that it can locate both sound sources that are inaudible to the
human ear, as well as sound sources that the human ear cannot reliably lo-
cate. The FLIR Si124 has a frequency range that extends to ultrasonic fre-
quencies, which is a huge benefit since many interesting problems and
phenomena can be located precisely using ultrasound.

The front side of the camera consists of a video image sensor (1) and the mi-
crophone array (2). The video shown on the display is monochromatic (black
and white) and the acoustic image is colored.
The camera has a resistive touch screen (3). The screen can also be used
with gloves. Only touch the screen using your finger - do not use the touch
screen with anything sharp or with hard objects, which may damage the sur-
face. Do not exert excessive force when pressing the screen as it will affect
the durability of the touch screen.
The main power source is an external battery which is connected to the bot-
tom of the handle (4). The camera comes with a battery cable (5) which can
be attached to the camera. Only use batteries and cables provided with the
camera or otherwise approved for use with the camera.
The status of the internal power supply unit is indicated by the power LED (6),
which is red when the power is on. While the power is on the camera dissi-
pates heat through the three heatsinks (8, 9, 10) which are located on both
sides and the top. While using the camera the heatsinks must be uncovered
to ensure that the heat dissipation works properly. Do not bag the device while
the Power LED is on. Please note that the heatsinks sometimes get hot after
prolonged usage, so be careful when touching the heatsinks.
There are two ways to export the results from the camera - using the included
FLIR Acoustic Camera Viewer service which requires a secure wifi connec-
tion, or through USB export (if available on your unit). The USB port is located
under the cover on top of the device (7). Please use the included USB memo-
ry stick for result export.
Note Protect the camera lens and the microphone array from any kind of
foreign objects, dust, and liquids.

7.1 Charging
The main power source of the camera is the battery. It should be charged fully
before usage - also make sure the battery is charged before prolonged stor-
age. To charge an empty battery fully usually takes 4-6 hours. Please note that
the battery should be charged at temperatures between 0°C and +40°C (+32°
F to +104°F). A new battery used in optimal environment conditions yields
over 7 hours of usage.
The battery and the charger is delivered with the camera. Only use the pro-
vided battery charger. Plug the mains cable of the charger into the wall socket
and the DC connector to the charging connector of the battery (2). When the
status LED of the charger is red the battery is being charged. When the status
LED of the charger is green while the DC connector is connected to the bat-
tery the charge is complete. The status LED is also green when the DC con-
nector is disconnected.

Nominally the battery yields 7-8 hours of usage. Though the battery usage de-
pends on multiple variables which may decrease the usage time. These are
the cell temperatures, the load and the age (cycles) of the battery.
7.3 Startup
The camera will start automatically when the power supply is connected. The
camera will shut down automatically when the battery is disconnected.
If the battery is disconnected accidentally and immediately reconnected to
the camera the unit will reboot. When shutting the device down, it is recom-
mended to wait until the power LED is off before connecting the battery power
supply again.
1. Attach the battery cable to the battery. The connector of the battery cable
can be attached to the battery connector (1) only one way.
2. Attach the connector to the camera according to the following instructions,
with the orientation markings facing the same way:
Both the camera and the battery cable have red orientation markings. They
indicate the position of the key and the slot of the connectors which ensures
the proper connection orientation. Hold the battery cable connector by the
locking ring and make sure that the orientation markings of both connectors
are aligned before inserting the battery cable. Then carefully insert the bat-
tery cable connector to the camera. The connectors should lock audibly.

7.4 Shutdown
To turn off the camera, simply disconnect the battery connector from the
camera.
Note Do not pull by the cord or use any kind of tool to disconnect the cable.
1. Hold the battery cable connector by the locking ring and pull it outwards.
The locking ring will slide until it releases the connection. Alternatively dis-
connect the cable from the battery.
2. The FLIR logo will appear and the system will safely perform a shutdown.
3. The red Power LED will turn off when the shutdown is complete.
If you encounter a problem with the system, a hard shutdown is performed by
disconnecting the battery power and waiting longer until the power led will turn
off. If the shutdown takes more than a 5 minutes after disconnecting the bat-
tery, contact FLIR Systems for service.

User interface
8
The camera supports the following application modes:
•Air mode is used for localization of pressurized air leaks.
•Power mode is used for localization and classification of high-voltage parti-
al discharges.
The available functions, settings, and real-time analysis information in the
user interface depend on the selected application mode.
An example of the graphical user interface of the camera is shown below.
8.1 Heatmap
The main view of the user interface shows the camera image with a heatmap
overlayed on top. The heatmap shows the location of the strongest sound
source (single-source mode) or multiple sound sources (multi-source mode).
There are two different types of color modes for displaying the heatmap.
#T810536; r. AB/63437/63437; en-US 12

User interface
8
Location color mode Strength color mode
The location color mode shows each sound source with several different col-
ors, ranging from blue to red. The center of the sound sources is shown with
red color, while the color gradually changes via yellow, green, and cyan to
blue outwards from the center of the sound source. The location color mode
is active in the Power application mode.
The strength color mode shows each sound source with a single color accord-
ing to the intensity of the sound source. The strength color mode is active in
the Air application mode. (Exception: When the SLM filter is enabled in Air ap-
plication mode, the location color mode is active.)
In addition to the heatmap, the location of the strongest sound source is
shown with a small crosshair. When taking a snapshot, the sound arriving
from the direction of the crosshair will be recorded. Application-specific real-
time analysis will also use the sound arriving from the direction of the
crosshair.
8.2 Take snapshot
Press the snapshot button to take a snapshot containing the current camera
image and heatmap as well as a short recording of the strongest sound
source. The direction of the strongest sound source is shown with a crosshair.
#T810536; r. AB/63437/63437; en-US 13

User interface
8
The record time is by default 2 seconds and can be selected by the user.
When pressing the snapshot button, the previous 2 seconds of the sound
from the strongest source will be saved. This means, that if you are observing
a sporadic event, you can press the snapshot button immediately after you
have observed it. This also means that it is recommended to keep the camera
stable for a few seconds before taking a snapshot in order to get a clear signal
from the source of interest.
When taking a snapshot, a keyboard will be displayed, which you can use to
enter optional comments about the snapshot. After entering comments, press
the button in the upper right corner to save the comments and the snapshot. If
you at this stage choose not to save the snapshot, press the garbage bin but-
ton in the upper left corner instead.
8.3 Snapshot browser
The number of snapshots currently saved on the camera is shown to the right
of the snapshot browser button. If there are two dots visible next to the num-
ber, snapshots are currently being uploaded to the FLIR Acoustic Camera
Viewer.
Press the button to browse through the snapshots. On the bottom of the
screen, thumbnails of the snapshots are shown, and you can scroll through
these horizontally. When you press a thumbnail, the snapshot will be shown
together with additional information.
Note Note that snapshots are not available in the snapshot browser after
they have been uploaded to the FLIR Acoustic Camera Viewer service or ex-
ported to a USB memory stick.

8.4 Zoom
The camera is equipped with a 2x digital zoom, which can be used for close-
up snapshots. Press the zoom button to zoom in or zoom out.
8.5 Single-source / multi-source mode
Press the single-source /multi-source button to toggle between the two
modes. In single-source mode, the camera shows only the sound source with
the highest intensity (with a crosshair on top). If there are multiple sound sour-
ces with the same or almost the same intensity, they will all be shown.
In multi-source mode, the camera shows multiple sound sources with different
intensities. The sound source with the highest intensity will be shown with a
crosshair on top. Not all sound sources will be shown. For example, if there is
a very strong sound source shown, very weak sound sources will not be visi-
ble at the same time.
To see weaker sound sources (in either single-source or multi-source mode),
position and rotate the camera so that stronger sound sources are outside the
field of view. You can also use the zoom button to limit the field of view.
8.6 Screen brightness
The brightness of the display can be adjusted by pressing the brightness but-
ton. This is useful to make the display readable under different lighting condi-
tions (indoors/outdoors).

8.7.3 Advanced settings
Press the Advanced settings button to access parameter settings for real-time
analysis calculations, such as leak size and cost estimation.
8.8 Filter
Press the filter button to switch between different filters. The available filters
depends on the selected application mode. The filters typically change the
frequency range that the camera uses for showing sound sources. The same
frequency range is also used when taking a snapshot and the sound is
recorded.
Try the different available filter settings to see which filter serves your applica-
tion best. Remember that the most appropriate filter might vary from case to
case, and depend not only on the sound source of interest, but also on the
background noise. For more information on choosing filters, see section 9.2
Locating sound sources and taking snapshots.
