FCC NOTICES:
This device complies with part 15 of the FCC Rules:
Operation is subject to the following conditions:
1.
This device many not cause harmful interference, and
2.
This device must accept any interference received, Including interference that may
cause undesired operation
Warning:
Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the
equipment.
Operation of this device is restricted to law enforcement, fire and rescue officials,
scientific research institutes, commercial mining companies, and construction
companies. Operation by any other party is a violation of 47 U.S.C. § 301 and
could subject the operator to serious legal penalties.
Coordination Requirements.
(a) UWB imaging systems require coordination through the FCC before the equipment
may be used. The operator shall comply with any constraints on equipment usage resulting from
this coordination.
(b) The users of UWB imaging devices shall supply detailed operational areas to the
FCC Office of Engineering and Technology who shall coordinate this information with the Federal
Government through the National Telecommunications and Information Administration. The
information provided by the UWB operator shall include the name, address and other pertinent
contact information of the user, the desired geographical area of operation, and the FCC ID
number and other nomenclature of the UWB device. This material shall be submitted to the
following address:
Frequency Coordination Branch., OET
Federal Communications Commission
445 12th Street, SW
Washington, D.C. 20554
ATTN: UWB Coordination
(d) Users of authorized, coordinated UWB systems may transfer them to other qualified users
and to different locations upon coordination of change of ownership or location to the FCC and
coordination with existing authorized operations.
(e) The NTIA/FCC coordination report shall include any needed constraints that apply
to day-to-day operations. Such constraints could specify prohibited areas of operations or areas
located near authorized radio stations for which additional coordination is required before
operation of the UWB equipment. If additional local coordination is required, a local coordination
contact will be provided.
(f) The coordination of routine UWB operations shall not take longer than 15 business
days from the receipt of the coordination request by NTIA. Special temporary operations may be
handled with an expedited turn-around time when circumstances warrant. The operation of UWB
systems in emergency situations involving the safety of life or property may occur without
coordination provided a notification procedure, similar to that contained in CFR47 Section
2.405(a)-(e), is followed by the UWB equipment user.
NOTICE: Use of this device as a wall imaging system is prohibited by FCC regulations.

Introduction
HandyScan is a small-size, fully functional ground penetrating
radar. It can instantly find the position and depth of metal and nonmetal bars, pipes and cables. It works in natural and man-made
non-conductive materials (concrete, rock, sand, brick, water, and
ice). It can also locate voids and measure the thickness floors and
other structural elements.
HandyScan allows the user to:
•
•
•
•
•
Collect single lines of data (page 4) or grid data for
plan viewing (page 8).
Review data on screen, determine position and depth of
features (page 5).
Print data on the Seiko DPU-3445-20 printer supplied with the
system (page 6).
Transfer data to a PC in GSSI (*.dzt) format for storage and
processing in RADAN software (page 7).
Display plan views (Depth Slices) of grid data on a PC screen
(page 9).

Data Collection
1. Press and hold Start (single beep).
2. Move unit forward.
3. Slow down if signal sounds when moving.
4. Press Mark when desired to insert marks in data.
5. Release Start to finish (double beep).
Start/Kill Switch
The Start switch also has a deadman switch function. The FCC
requires that when the operator stops interacting with the system
for ten seconds, the transmitter is to be shut off. This will also
close the data file that you have been acquiring. Thus you will
need to keep the Start switch on the handle depressed at all times
during data collection.
Note:
•
Pressing Start one more time will erase the data.
•
Print the data or transfer them to a PC if you wish
to keep the record before collecting the next line.
•
The HandyScan can store 15 m (50 ft) of data. The unit will
stop collecting data after this amount has been reached.
You will need to start a new file to resume collecting data.
•
The HandyScan displays axes in metric units only, but the
same data can be later displayed using RADAN NT
software on a PC in metric or English units.

Data Review
1. Use right/left arrow keys to scroll data.
2. Optimize data display:
•
Press Gain until best display of features is achieved. Gain
status is shown at bottom left (Gain can be used during
collection as well).
•
Press PRCS, then up/down arrow to change processing
method. PRCS method used is shown
at bottom center.
•
Use Set to modify display setup (contrast, amplitude, depth
scale, etc.).
3. Label targets:
•
Use arrow keys to move the cursors and locate targets. The
cross-hair X (position) and Y (depth) are displayed in the
top left corner.
•
Press Mark to label a target and display its X-Y along the
right edge of screen (up to 7 targets).
Note: It is possible to transfer non-grid data to a PC and review
them on the PC screen, taking advantage of a higher quality
display and (if installed) processing capability of RADAN
software. Please see Data Transfer (page 7) and RADAN manual
for instructions on processing.

Radar Wave Velocity Adjustments
1. Automated processing includes Migration which removes
hyperbolic reflections from the data. Migration requires Radar
Wave Velocity to be set within ½ in/ns of the exact value.
2. The exact velocity is usually not known, thus trial-and-error is
the best way to determine it:
•
After first processing, maximize Display Gain and see if
the hyperbolas have collapsed into dots:
Raw Data
Velocity too high
Correct
Velocity too low
•
Correct velocity – data can be viewed in Depth Slices
•
Velocity too high or too low – process again, respectively
decreasing or increasing velocity in
½ in/ns steps until image looks correct.
