INTRODUCTION  
The 3MDynatel2210E 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.

to select the 50/60 Hz power frequency (see section on  
Selecting Passive Power Frequencies Page 9) or LF for passive locating;  
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  
high-expanded. The high-expanded setting causes the audio to cut off as  
the antenna moves away from the cable.  
Note: While tracing cables, keep the Receiver handle in line with the  
suspected cable path.

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  
frequency.

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.
