2.1 General information about the system
2.1.1 Communication
The components of the AQUAPHON system communicate by
bidirectional SDR (SDR: Sewerin Digital Radio). Wireless com-
munication allows the user considerable freedom of movement.
Thesoundqualityoftheacousticplaybackisnota󰀨ectedby
swinging cables.
2.1.2 Hearing protection
The AQUAPHON system protects the user's hearing against
sudden, loud interference noise. This type of interference noise
canoccur,forexample,whenvehiclesdrivebyorwhentheuser
withatouchmicrophoneslipso󰀨thecontactpoint.
The hearing protection function activates when the individu-
alhearingprotectionthresholdsettingisexceeded.Whenthe
noise from the source of interference ceases, hearing protection
switcheso󰀨againautomatically.
The way the hearing protection works depends on the settings
(Measurement menu > Hearing protection).
Note:
Another way of protecting the hearing from loud noises is to set
the volume only as high as is absolutely necessary.
2.1.3 Operating concept
Working with the AQUAPHONsystemrequiresspecialistknowl-
edgeofleakandpipelinelocation.Youdonot,however,require
any special skills to use the system itself, as it can guide you
through the process.
To ensure successful location with the AQUAPHON system, all
users must know:

 2AQUAPHONsystem│ 5
●What is to be located?
The purpose determines the choice of application.
●Where is it to be located?
Conditions on the ground determine the choice of contact
point.
2.1.3.1 Switch-on mode
The receiver always automatically determines the switch-on
mode. There are two options:
●Startup with user guide
●Direct startup
The situation when the receiver is switched on determines which
switch-on mode is used. The receiver checks whether or not cer-
tain steps have already been performed. These steps include:
●System components have been connected (e.g. carrying rod
and a ground microphone).
● System components have already been switched on before
the receiver.
For more detailed information about switching on dependent on
switch-on mode, please refer to section 3.2 on page 21.
Startup with user guide
Target
group:
Userswithlittleexperienceofusingthesystem.
– The user is unsure of which system components
to select for a certain application and the corre-
sponding contact point.
Theuserrstswitchesonthereceiver.Onceanapplicationand
the contact point have been selected, the receiver provides de-
tailed instructions about which components are to be connected
and switched on in what order.
Direct startup
Target
group:
Experiencedusers.
– The user knows which components of the sys-
tem to select for a certain application and the
corresponding contact point.

6 │2AQUAPHONsystem
The user starts by selecting the suitable components. Compo-
nents that need to be connected mechanically are connected
by the user. The user then switches on the components before
switching on the receiver last. The receiver automatically recog-
nises the components as it is switched on.
With Direct startup, the system is ready to use as soon as the
receiver is switched on.
2.1.3.2 Applications
The names of the applications correspond to their possible uses.
The system can be used for:
●Leak detection
●Pipe location
2.1.3.3 Contact points
Each application allows the system to be used on certain contact
points. The contact point is the area on which a microphone is
placed.
The following contact points can be selected:
●Paved
Thecontactpointhasasmooth,rmsurface(e.g.asphalt,
concrete, plaster).
●Unpaved
The contact point has an uneven surface, which may some-
times give way (e.g. gravel, crushed stone, grass).
●Fitting (only for leak detection)
Thecontactpointis,forexample,ahydrantorslidegate.
●Universal (only for leak detection)
The contact point is located inside a building.
This option is intended for locating leaks and pipes with the UM
200 universal microphone.

ponents are as follows:
●A 200 receiver
●F8 wireless headphones
●TS 200 carrying rod
Thecarryingrodisrequiredwhenusingthefollowingmicro-
phones:
−BM 200 ground microphone
−BM 230 ground microphone (with tripod)
−TM 200 touch microphone
Aprobetipandpossiblyanextensionarerequiredforthe
touch microphone.
●UM 200 universal microphone
●AC 200 SK4 case
The system can be transported and stored in the case. The
batteries for the components A 200, TS 200 and F8 can be si-
multaneously charged in the case using the AC/DC adapter L.
Accessories can be added to the system at any time.
Note:
Information about F8 wireless headphones can be found in the
relevant operating instructions.
2.2.2 A 200 receiver
2.2.2.1 Product variants
The receiver is available in two product variants:
●without module for position determination
●with module for position determination

8 │2AQUAPHONsystem
Devices with position determination link the measurement data
with the geographical coordinates (e.g. GPS) of the measuring
location.
Receivers with position determination module are
identiedbyasticker.
2.2.2.2 Setup
Overviews with the names of all the parts of the receiver can be
foundinsidethefrontcover(g.1andg.2).
Its symmetrical housing means that it can be operated by both
right-handed and left-handed users with ease.
Touch screen
The receiver features a touch screen. Certain areas of the touch
screen are touch-sensitive. Actions are performed by touching
these areas (buttons).
All of the buttons have a thick, dark grey outline.
Onlyyourngeroratouchpenshouldbeusedtooperatethe
touch screen.
● Alwaystouchthebuttonsbrieywithoutexertingtoomuch
pressure.
NOTICE! Risk of damage
The surface of the touch screen is sensitive.
●Do not use any hard or sharp objects (e.g. pens) to operate
the screen.
●Protect the touch screen against aggressive substances (e.g.
acidic or abrasive detergents).
Overviews with the symbols that might appear on the touch
screen can be found in section 6.2 on page 70.
Light sensor
The light sensor analyses the ambient lighting conditions.

 2AQUAPHONsystem│ 9
If the automatic brightness setting is enabled, the light sensor
always adjusts the brightness of the touch screen to the ambient
lighting conditions.
Information about the automatic brightness setting can be found
in section 4.5.3 on page 54.
ON/OFF key
The ON/OFF key has the following functions:
● Switchingthereceiveronando󰀨
●Locking and unlocking the display
Activation keys
The receiver has two activation keys. Only one of the two keys
needs to be pressed to measure.
LED
The LED indicates the operating status.
Information about what the LED signals mean can be found in
section 6.3.1 on page 72.

or a hand loop can be attached to the connectors.
Theconnectorsarepartsofthequick-releasefasteners.

10 │2AQUAPHONsystem
2.2.2.3 Carrying the system
The receiver is usually carried in front of the body so that the user
looks diagonally down at the touch screen.
SEWERIN recommends: Use a carrying system for locating op-
erations. The carrying system prevents you from tiring during
work. It also reduces the possibility of radio interference. Ra-
dio interference can occur if the user accidentally covers certain
components in the receiver.
2.2.2.4 Playing back noises
The connected microphone records noises. When a measure-
ment is ongoing, the noises are played back through the head-
phones. You can set the volume of the playback.
The noises are also recorded. Recorded noises can be saved.
Both recorded and saved noises can be played back.
2.2.2.5 Displaying the measurement values
Various measurement values are calculated from the recorded
noises(e.g.currentnoiselevel,extremevalueofthemeasure-
ment).
The measurement values can be displayed in two ways:
●Visually
●Numerically
Visual representation
The measurement values are displayed visually on the touch
screen in the main view (volume button):
●Current noise level (level display)
● Extremevalue(blackline)
Numerical representation
The measurement value for the noise level is displayed as a nu-
meric value in the centre of the main view on the touch screen.
Thismeasurementvalueisanextremevalue.Whethertheex-
tremevalueisaminimumormaximumdependsonthesettings
(Measurement menu > Type).

 2AQUAPHONsystem│ 11
2.2.2.6 Automatic power o󰀨
The power supply to the receiver is designed in such a way that
a fully charged battery will allow one full day's work without in-
terruption. However, it is still recommended to conserve energy
whilst working.
Thereceiverthereforeo󰀨ersthefollowingautomaticpower-o󰀨
options:
●Switch o󰀨 device
Thereceiverswitcheso󰀨ifitisnotoperatedforaspecied
period of time. It must be switched back on again when you
want to continue work.
●Switch o󰀨 backlight
Thereceiverbacklightswitcheso󰀨ifitisnotoperatedfora
speciedperiodoftime.Thereceiverremainsswitchedon.
Ifandwhentheautomaticpowero󰀨isactivateddependsonthe
settings (Device menu > General > Switch o󰀨 device or Switch
o󰀨 backlight).
2.2.2.7 Main view
The touch screen of the receiver displays the main view when
the system is ready for use.
