Section 1: Getting Started
This section assumes that you are using WiFi to connect to the UtilityScan.
1GSSI recommends fully charging the batteries and the tablet prior to use.
2Unfold the UtilityScan cart and place the tablet into the mount.
3Slide a fully charged battery into the battery slot at the top of the UtilityScan until the battery release lever at the
front of the battery opening locks into place. The groove along the top side of the battery should face up.
To eject the battery, push down on the battery release lever.
4Push the Power button on the top of the UtilityScan housing. A blue ring will illuminate around the button.
The UtilityScan is booting up and is ready to connect to the tablet when the blue ring begins to flash.
5Turn on the tablet and tap the UtilityScan icon. You will briefly see the UtilityScan splash screen as the UtilityScan
app boots up and then the connection screen will appear.
Note: The blue ring around the power button also indicates the WiFi connection status. A flashing blue ring indicates
that the UtilityScan WiFi is broadcasting and ready to connect. A solid blue ring indicates that the system is actively
collecting data.

Connecting to the UtilityScan with WiFi
1Make sure that the UtilityScan is turned On and
tap the UtilityScan app icon. After a short splash
screen, you will see the image at the right. This
image shows five UtilityScans are broadcasting
nearby. You will likely see only one entry.
2The center of the screen will show one entry for
each UtilityScan the app detects. Individual
systems are identified by their serial numbers
which will show after the zeros.
3Tap the box next to the correct UtilityScan entry
and then tap Connect. The connection will
establish after a few seconds and UtilityScan Main Menu screen will appear.
Note: The UtilityScan app will remember the last UtilityScan antenna to which it connected. The next time you open
the app, it will auto connect if it detects the last UtilityScan antenna. The connection screen will flash and the go to the
Main Menu screen. If you have multiple UtilityScan antennas, be sure to turn them on and connect one at a time. Once
connected, the UtilityScan antenna will not connect to another tablet until disconnected from the its current tablet.

UtilityScan Quick Start Guide Page 7
Connecting to the UtilityScan via Ethernet
1Make sure that both the tablet and the UtilityScan antenna are powered Off.
2Unscrew the protective cap covering the antenna Ethernet connector and connect the Ethernet cable to the antenna.
Connect the other end of the Ethernet cable to the tablet. Note that you may need to use the included adapter cable
depending on your tablet.
3Power on the antenna first and wait for the blue light around the antenna power button to flash before turning on the
tablet.
4Power on the tablet and note the Ethernet symbol <…> in the top-right corner of the Android desktop. If you do not
see it wait for it to appear before going on to the next step.
5Tap the UtilityScan app icon. The system is now communicating over Ethernet and the WiFi radio on the UtilityScan
antenna will automatically turn off after 15-20 minutes.
Note that the WiFi radio on your tablet will remain on. If you are in an environment where WiFi is not permitted, you can
turn it off by following these steps:
1From the Android tablet desktop, tap Settings:
2Tap Wi-Fi from the Wireless & Networks section
at the top.
3Tap the slider toggle on the top right to turn WiFi off. Remember to turn it on again to use WiFi in the future.

Connecting/Disconnecting to Another WiFi Network and Navigating WiFi in Android
There may be times when you want to connect your tablet to another network to download updates. Bear in mind
however, that you should treat this tablet as part of the GPR data collection instrument and avoid loading unnecessary
apps such as games, etc.
To connect to a wireless network:
1Turn your UtilityScan antenna Off.
2From the Android tablet desktop, tap Settings.
3Tap Wi-Fi from the Wireless & Networks section at the top. You will see a list of available networks.
Tap the one to which you want to connect.
4Input the network password.

UtilityScan Quick Start Guide Page 9
Note:You will need to manually disconnect from any non-UtilityScan connections before connecting to the antenna.
You will need to do this even if the network you had connected to is off or out
of range. Follow these steps to do so:
1From the Android tablet desktop, tap Settings.
2Tap Wi-Fi from the Wireless & Networks section at the top. You will see a
list of available networks. Tap the one to which you want to disconnect.
A box with the network information will pop up.
3Tap Forget. You can now connect to the UtilityScan antenna normally.

First Time Setup
1Set Language: Make sure that the UtilityScan is in the ScanMax App. Tap on the Secondary Menu
softkey in the Menu Carousel to display the secondary menu. Tap Select Language and choose your
desired language.
2Set Units: Tap Units from the Menu Carousel to toggle between English (Imperial) and
Metric units.
3Calibrate Antenna: This option will run an auto-calibration routine on the antenna signal position. Assuming a
correct dielectric value, this will ensure your depths are more accurate.
4Calibrate Survey Wheel:While there is minimal manufacturing variation in the survey wheel encoders, it is still
a good idea to occasionally calibrate the survey wheel to ensure distance accuracy.
5Save Prompt: Tap this to toggle the Save File courtesy check on and off. Setting this to Off will cause the
UtilityScan to automatically save each file.
The choices you have made here will carry over to the ScanEZ Collection Apps.
The status indicator shows (from left to right): 1) Antenna battery power. 2) Tablet storage.
3) Antenna connectivity (white = positive, gray = negative). 4) LineTrac module (white = on,
gray = off, crossed = damaged. 5) GPS indicator.

Section 2: Using ScanEZ
Application
Before collecting any data, you may want to configure
your UtilityScan. Tap ScanEZ from the App Carousel.
1Choose Inspection Depth: Tap Depth to toggle
through the pre-set depth settings. GSSI
recommends setting the inspection depth a little
deeper than required.
2Set Soil Type: GPR energy travels at different
speeds though different materials. Setting this close
to the material type through which you are scanning
will provide more accurate depth readings. These
names refer to the majority of material, not just the surface cover. See Appendix A in this guide for details.
3Choose Color Table: This will set the data display color. GSSI recommends that new users choose
Color Table 1.
4Once you have configured the UtilityScan, tap Collect to begin collecting data.
Note:The UtilityScan will detect the direction of first movement as “Forward.” This means that if you pull the
cart backwards as the first movement after tapping collect, the UtilityScan will collect data going backwards.
This will not change the direction which the data file scrolls on the screen.

UtilityScan Quick Start Guide Page 13
Collecting Data and Marking Targets with Scan EZ
The image at the right shows
the tablet screen while the
UtilityScan is actively
collecting data. Data will be
added to the left edge of the
screen as you push the cart.
The left edge ruler indicates
a depth estimate based on the
current dielectric value. The
current project number and
file name are shown at the
top-left corner of the top bar.
The top bar also indicates
depth, linear position,
dielectric, and current app.
Targets such as pipes will
appear as hyperbolas when
crossed at a 90-degree angle.

Hyperbolas from targets

UtilityScan Quick Start Guide Page 14
The image at the right shows the buttons
active on the bottom Menu Carousel
when the UtilityScan is backing up to
mark a target.
Once you have identified a target which
you want to mark, simply back up the
UtilityScan in a straight line. You will
see the yellow vertical backup cursor
appear on the screen. Move the
UtilityScan until the cursor bisects the
hyperbola. Draw a mark on the ground
lining up with the marking grooves on
the side of UtilityScan cart.
The image at the right shows the Gain
function. Gain will help to brighten the
screen contrast and may make it easier
to see targets. Tap Gain to bring up the
control sidebar. Gain Level will affect
the whole vertical scale while Shallow and Deep will focus on those portions of the image.
Tap Save Image to save a screen shot of the current view.
You must save the data file and transfer it to your PC in order to access the saved image.
