INTRODUCTION
The 3M™ Dynatel™ 2210E Cable Locator consists of a Transmitter and a
Receiver for locating buried cables or Active Duct Probes (sondes). It also
can be used to identify cables or pairs using a Dyna-Coupler plugged into
the Receiver jack. The Transmitter provides two frequencies to
accommodate varying factors such as distance, cable type, or soil
conditions. The Receiver detects 50 or 60 Hz AC Power signals and low
frequency (LF) radio signals re-radiated form local broadcast transmitters.
It also measures the signal current in a cable and displays its magnitude.
The depth of buried cables or sondes may also be displayed.
Note: For more detailed locating instructions and advanced locating
techniques, ask your 3M sales representative for a free publication called
Cable and Pipe Locating Techniques.

TRANSMITTER BATTERY TEST
To test the Batteries, hold down
and listen to the tone (solid
tone=good; beeping tone=low; no tone=replace batteries).
Note: The battery test indicates battery condition for normal output
levels. If the unit resets when the high output level is selected, use the
normal output level or replace the batteries.
LOCATING A BURIED CABLE
Transmitter Setup
Note: Key descriptions can be found inside the Transmitter lid.
Perform a battery test and then connect the Transmitter using one of the
three methods below to put tracing signal on a cable.
DANGER!
Check for stray voltage before attaching Transmitter. Voltage greater
than 240 volts will damage equipment and cause personal injury and
death. Follow standard procedures for reducing the voltage.
WARNING!
Potential for electrical shock exists when handling connecting cables
while the Transmitter is in the TRACE, FAULT or TONE modes.
Turn the Transmitter off before handling connecting cables.

Direct Connect Method
Make sure the Transmitter is off. Plug the direct connect cable into the
front panel jack. Connect the Black clip to the ground rod. Place the
ground rod in the earth perpendicular to the suspected cable path. If
necessary, extend the black lead with the Ground Extension Cable. Remove
the ground bonding and attach the Red clip to the shield.
Note: Never attach or remove the direct connect cable from the Transmitter front
panel jack while the red and black clips are connected to a cable.
Press
to turn the unit on and select Continuity Test (solid
tone=good ground; beepingtone=usable ground; no tone=poor
ground or no far-end ground). Both LEDs light continuously
during the continuity test.
Press
to apply Tracing signal and select the desired frequency: 577 Hz
for direct connect with far-end ground; or 33 kHz for direct connect with
no far-end ground. LED indicates frequency selection. (This key can also
turn the unit on.)
Press
to change output level. Choose Normal output (flashing LED)
for locating short to moderate distances using direct connect method. Use
High output (solid LED) for long distances and deep cables.
Transmitter setup is finished, now go to LOCATING A BURIED CABLE

coupler cable.
Clamp the Dyna-Coupler around the cable below any bonds just before the
cable enters the earth. The jaws of the coupler must fully close.
Press
to apply Tracing signal and select the 33 kHz frequency. LED
indicates frequency selection. (This key can also turn the unit on.)

otherwise, select the same frequency as the Transmitter.
Note: The Receiver is automatically set to Special Peak mode when LF is
selected. No other modes are allowed in LF frequency.
Press
to adjust the speaker volume as needed: off, normal, high, or

About Trace Modes
Peak: In this mode, as the antenna crosses the cable, the Receiver speaker
volume increases to a maximum and the bar graph fills from both sides
toward the middle. As the antenna moves off the cable path, the speaker
volume decreases and the bar graph opens.
Peak with High-Expanded: While in Peak mode, press
to select
High-Expanded (the highest setting). Speaker response is cut off as the
antenna moves away from the cable.
Special Peak Mode: This mode will increase the signal sensitivity of the
Receiver when the signal is too weak for normal tracing. Use special attention
when using this mode because it is more susceptible to congestion than the
normal peak mode. To select Special Peak mode, press and hold
then press
. While in this mode the Peak flag will flash.
Note: While tracing cables in any mode, keep the Receiver handle in line with the
suspected cable path.
See section Initial Receiver Configuration (Page 3) to set the power
frequency to 50 Hz or 60 Hz. The Receiver can be tuned to locate 3
different harmonics of the chosen power frequency.
H50 Hz or H60 Hz (high harmonic): Best for general locating of
passive power.
L50 Hz or L60 Hz (low harmonic): Works best on primary power
cables. May be used when high harmonic is weak or erratic.
100 Hz or 120 Hz: For locating rectified AC power signals, often found
on pipelines using impressed current cathodic protection.
When a Power frequency is selected, the Hz symbol will flash, indicating
that alternate frequencies are available. To change the selected power
frequency, press and hold

LOCATING EMS MARKERS
EMS markers may be detected and located using either the 3M Dynatel™
2205 or 2206 EMS Marker Locating Accessory. To attach the accessory,
slide the Receiver horizontally into the EMS Marker Locating Accessory
mounting slot. Make sure the locking button holds the Receiver securely
in the slot. To separate the units, press the locking button down and slide
the Receiver out of the EMS Marker Locating Accessory mounting slot.
Locating Markers while Tracing Cable Path
To detect markers while tracing the cable path, set the 2205 or 2206
accessory mode switch to the Alert position, and trace the cable path
normally. The internal buzzer in the accessory will alert you to the
proximity of a detected marker.
Locating Markers using the Receiver
If the buzzer response is too broad, the exact marker position may be
pinpointed by using the Receiver.
Select 577 Hz or 33 kHz on the Accessory. Use a different
frequency from the tracing signal.
Turn the Receiver ON and set the frequency to match the Accessory
setting.
Note: The initial Receiver gain in Peak mode is optimized for interfacing
with the 2205 or 2206 Accessory while searching for a marker. Press
only when a marker is detected and the signal is too strong. To search for
a new marker, reset the Receiver gain to the initial setting by turning its
power OFF and back ON.
Refer to the EMS Marker Locating Accessory operating instructions for
further information.

CABLE OR PAIR IDENTIFICATION
Transmitter Setup
Transmitter setup is the same to identify cables or pairs. However, Receiver
setups are different.
Perform a battery test; then, connect the Dyna-Coupler to the Transmitter
front panel jack using the coupler cable.
Note: Cable Identification requires two Dyna-Couplers: one at the
Transmitter and one at the Receiver.
Clamp the Dyna-Coupler around either the cable or both tip and ring of a
pair and make sure the jaws fully close.
Press
LED indicates the frequency selection.
Press to change the high output level.
to turn the Transmitter on and select the 33 kHz frequency.
Receiver Setup
Connect a second Dyna-Coupler to the Receiver accessory jack another
coupler cable.
Note: Cable Identification requires two Dyna-Couplers: one at the
Transmitter and one at the Receiver.
Press
Press
to turn the Receiver on.
to select the highest toning frequency.
Check the first cable in the group by clamping the Dyna-Coupler around
the cable. Press and observe the numeric display, which is relative
signal strength. Remember the number and continue by clamping the
Dyna-Coupler around the next cable in the group. If the signal strength is
greater than the previous observation, press
. If the signal strength is
less than before, ignore it. After checking all the cables in the group, the
cable with the highest reading is the one being identified.

PAIR IDENTIFICATION
Receiver Setup
Connect the inductive probe to the Receiver accessory jack using the
probe cable.
Press
Press
to turn the Receiver on.
to select the 33 kHz frequency.
Insert the Probe into the bundle of pairs (or the group, if known) and
press . Next, divide the pairs into two bundles and insert the
Probe into each of the bundles and observe the numeric display. The
bundle with the highest reading will contain the target pair. Continue
by dividing the bundle with the target pair into two parts and checking
each part for the highest signal. In this way the pair to be identified
will be isolated.
