●Only use accessories and consumables approved by Hermann
Sewerin GmbH.
If not described otherwise: Standard batteries or rechargeable
batteries can be used for the power supply of the products.
●At the same time, always use power sources that are identical
in terms of type (battery or rechargeable battery), capacity,
manufacturer, charge and state (new or used).
●Always observe the permitted operating and storage
temperatures.
●Before starting the location work obtain information about the
route of buried cables and lines from local utility companies.
●Always adequately cordon off the work area.
●Never operate the product in the vicinity of explosive areas.
●Protect the ports and sockets on the product against dirt, and
electrical ports in particular against moisture.
●Do not submerge the product in liquids.
●When you are wearing headphones, you are not fully
aware of ambient noise. Be especially vigilant, especially in
environments with an increased risk of accident (e.g. traffic).
●Only set the volume as high as absolutely necessary. Excessive
noise can cause permanent damage to your hearing.

and operation. Protect the rechargeable battery against
very low and high temperatures even when these are in the
permissiblerange.
●Only charge the rechargeable battery using the relevant AC/
DC adapter.
●Never place the rechargeable battery on an open fire.
●Dispose of the rechargeable battery in accordance with
applicableguidelines.

2 System overview
2.1 General information
System UT 9200/9100 can be used for active and passive
locating. During active locating the required electromagnetic field
is generated with a generator. During passive locating existing
electromagnetic fields are used.
SEWERIN recommends: Always check the plausibility of the
system’s locationresults.
2.2 System components
The system has a modular construction. The main system
components are as follows:
UT 9200 system UT 9100 system
Receiver
UT 9200 R UT 9100 R
Generator
UT 9012 TX or UT 9005 TX
Software
UT configurator
App

The receiver and generator can be transported and stored in
bags.
Information about the receiver can be found in section 3 and the
generator in section 5.

UT configurator software
The UT configurator software can be used to update and
efficiently configure the receiver and generator.
The software can be used to execute the following tasks, for
example:
●update firmware
●preset, activate frequencies
●create own frequencies (in addition to available ones)
●configure the device (receiver, generator)
●set up the start screen (e.g. company logo as background)
●save individual settings and load again at a different point in
time
Prerequisites for using the software:
●software is installed on a computer
●device is connected to the computer via a USB cable
The software can be downloaded free of charge from
www.sewerin.com.
Information on updates and configurations is provided in
section7.9.

●view measurements in the app's map view
●transfer data, for example, by e-mail to another device so that
the measurements can be saved there
Prerequisites for using the app:
●app is installed on a Bluetooth-enabled device
●receiver and Bluetooth-enabled device are connected
The UT 9200 Com app is available free of charge for Android
and iOS.

3 Receiver UT 9200/9100 R
3.1 General information
The receiver can detect signals from electromagnetic fields.
Signals are reproduced:
●visually on the display
●audibly via the loudspeaker or headphones
The field strength is shown graphically and numerically on the
display. The direction arrows and other graphical elements help
when approaching the location object just like the audible sound
and special signal tones.
The volume set for the loudspeaker or headphones does not
affect the sensitivity of the receiver, i.e. loud signals are not
necessarily strong signals.
You will find an overview of the receiver parts inside the front
cover (fig. 1).
