Signal overload - When the receiver is too close to the
inductive operated transmitter or a power transformer.
Shallow cable - When the cable is possibly less than 15cm
deep. Proceed with caution!
Swing alert - When excessively swinging the receiver. This
could result in misleading information.
Overhead cable - When the signal is mainly radiating from
above distorting the below ground signal.

Warnings - Are audible sound with a vibration of the handle.
Warnings can be activated or deactivated in the user menu.
Locating cables and pipes**
Passive location 50Hz / Radio / CTV)
(No compass available / Only peak and omni direction mode)
Switch on the vLoc3 series receiver.
Select the frequency with the "f"-button. (If the desired frequency
is not preset, switch to the user menu by pressing and holding
the "i"-button and choose it in the sub-menu "frequency". Press
the "Enter" button to highlight it. Go back with a short press on
the "i" button.)
Hold the receiver vertically and adjust the sensitivity by pressing
the “+” / “- ” buttons so that the bar graph shows a signal.
Continue locating in a grid across the area, see illustration (a) below.
Determine signal maximum by carefully moving the receiver back
and forth. Adjust the sensitivity again with the “+” / “- ” buttons.
Continue to locate the position of the line.
When locating in 50Hz or with a transmitter: Display depth / signal
current with short pressure on the "i" button or permanently in the
upper left display area.

Switch on the transmitter and select the desired frequency
with the "f" button (If the frequency is not preset, use the "i"
key to access "frequency selection" in the menu and mark the
desired frequency with the "f" key. Press the "i" key to return.
Always select the lowest possible frequency to minimize coupling
to other lines.
Set the output power accordingly. (less is more)
From this point on, follow points 1 through 6 of the Passive
location 50Hz / Radio / CTV section of this document.

Connect the transmitter with the supplied connection leads. Connect
the red wire to the target conductor and the black wire to ground.
The ground stake should be at a 90oangle to the target line if
possible. To reduce signal interference, there should be no other
lines (if possible) between the ground spike and the target line.
Active locating
Direct connection**
Connect the signal clamp to the transmitter and place it around the
corresponding target line.
Then follow points 1 - 3 from the Direct connection section of this
document.

Classic locate modes (vLoc3-Pro user manual page 10)
Available modes: peak, peak with arrows, null, broad peak, delta
null, omni direction.
The individual modes within the classic view can be changed by a
short press (<1 sec.) on the "Enter" button. If a mode is not visible
or not desired, it can be switched on or off in the user menu (long
press on the "i" key / classic display / selection with "Enter" key).
Locate Screens**
For all subsequent locating views, except Transverse Graph
and Sonde Mode:
The distortion level is displayed on the bar graph.
Green = low interference, Blue = some interference, and Red = high
interference level, treat the locating results with caution.
NOTE:
Locating views (classic, vector, plan view, transverse graph, and
sonde can be changed by a long press on the "Enter" key
(approx. 2 seconds).
Antenna
configuration:
Place the transmitter (without connection leads or clamp attached)
on the ground with the handle in the direction of the cable. Do not
place the transmitter on manhole covers, or other metallic objects
as the signal will not be able to penetrate them. When locating,
maintain a distance of at least 20m from the transmitter, otherwise
the airborne signal from the transmitter will be located and not the
target line. Now follow points 1 through 3 in the Direct Connection
section of this document.

Advantages: Simple location guided by directional arrows. Much easier &
faster handling.
The target line is below the receiver when
both signal peaks are on the center line
and the signal is not distorted.
The center line does not indicate the target
line, but serves as an orientation for the two
signal peaks and the alignment to the cable!
If the signal path is distorted, or the two signal peaks are not on the
center line, there is interference in the electromagnetic field. To
determine the exact position of the cable now, please refer to the
user manual, section "Distorted fields".
Advantages: Automatic gain adjustment; Optimal analysis of signal distortion.
