Congratulations! You have just purchased one of the finest, most advanced locating 
devices available today!
The 3M
™ Dynatel™ Pipe/Cable Locators 2550 Series and 3M™ Dynatel™ Cable/Pipe/
Fault Locators 2573 Series are designed with all of the functionality of previous 
Dynatel models plus the availability of 6 active locating frequencies and trace view 
locating mode, while the iD versions have the enhanced capability to read and write 
user information into the 3M iD markers. Information such as a pre-programmed 
identification number, facility data, application type, placement date and other details 
can all be read, stored and downloaded to your PC for enhanced resource management 
with this revolutionary equipment. The Dynatel 2550-iD Pipe/Cable Locators and 
Dynatel 2573-iD Cable/Pipe/Fault Locators will also search for two different types 
of utility markers simultaneously. When used in conjunction with a hand-held GPS 
device, the ability to transmit path and marker coordinates multiplies the potential to 
the mapping industry. This equipment provides a simple system for mapping utility 
information directly into CAD and GIS systems. The 2550/2573 Series transmitters are 
12 watt units. They provide .5 watts, 3 watts and 12 watts of output power. 12 watts is 
attained by utilizing the Cigarette Lighter Adapter or External Rechargeable Battery.
3M is dedicated to bringing you premium equipment with outstanding reliability, backed 
by one of the best warranties in the business and outstanding service.
Visit our website at www.3M.com/dynatel  for more application notes and product 
information.

1. Safety Information
Please read, understand and follow all safety information contained in these instructions 
prior to the use of the 3M™ Dynatel™ Pipe/Cable Locators 2500 Series. Retain these 
instructions for future reference.
Intended Use
The 3M Dynatel Cable/Pipe/Fault 2550/2573 Series Locators are used to identify the 
placement of underground utility lines. The system must be installed as specified in the 
3M
™ Dynatel™ Cable/Pipe/Fault Locator 2550/2573 Series Operator's Manual. It has 
not been evaluated for other uses or locations. If this equipment is used in a manner not 
specified by 3M, the protections provided by the equipment may be impaired.
Explanation of Signal Word Consequences
! Warning: Indicates hazardous situation which if not avoided, could result in 
death or serious injury.
! Caution: Indicates hazardous situation which if not avoided, could result in 
minor or moderate injury.
Explanation of Product Safety Label Symbols
Do not throw away in normal trash.
cWarning: Risk of electric shock
!
 WARNING
This WARNING applies to the following 3M Dyna-Couplers;
• 3" (75 mm) - Part number 3001
• 4.5" (114 mm) - Part number 4001
• 6" (150 mm) - Part number 1196
•    All accessory kits containing any of the listed Dyna-Couplers - Part numbers 3019, 4519, 
1196/C
A potential for electrical shock exists when using the Dyna-Coupler on c\
ables energized with 
electrical power. Use appropriate safety procedures.
DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS. 
						

							 6 78-9000-0192-2 Rev D
! WARNING
This WARNING applies to the use of the Direct Connect Cables and the Transmitter.
To avoid potential shock, or electrically damaging the Transmitter, when setting up the 
Transmitter to locate using the Direct Connect method, follow these basic steps;
•    ALWAYS plug the Direct Connect Cable into the Transmitter Output Jack [T-6] BEFORE 
connecting the leads to the cable/pipe to be located and the ground rod.
  – Connect the red lead to the cable/pipe. 
  – Connect the black lead to ground rod.
A POTENTIAL FOR ELECTRICAL SHOCK, AND/OR TRANSMITTER ELECTRICAL DAMAGE, EXISTS 
WHEN USING THE DIRECT CONNECT CABLE ON CABLES ENERGIZED WITH ELECTRICAL POWER 
IF THE ABOVE INSTRUCTIONS ARE NOT FOLLOWED. USE APPROPRIATE SAFETY PROCEDURES.
CHECK VOLTAGE BEFORE CONNECTING TRANSMITTER. VOLTAGE HIGHER THAN 240 VOLTS WILL 
DAMAGE EQUIPMENT. FOLLOW STANDARD PROCEDURES FOR REDUCING THE VOLTAGE.
2.  About This Manual
There are two basic models included in the 3M™ Dynatel™ Locator 2500 loctor Series. The 
2550 locator is designed for pipe/cable locating. The 2573 loctor is designed for cable/pipe 
and fault locating. The iD option (read/write capability to 3M
™ iD Markers) is available for 
both models. The 2550/2573 Series transmitters are 12 watt units. They provide .5 watts, 3 
watts and 12 watts of output power. 12 watts is attained by utilizing the Cigarette Lighter 
Adapter or External Rechargeable Battery. This instruction manual will include all features. 
All instructions are applicable to all products, unless noted. 
The 12-watt transmitter offers additional power output levels for improved induction 
performance and 8 kHz (low frequency) induction for shallow facilities, such as risers. 
The maximum output power in Direct Connect method is reduced to comply with FCC 
limits. (FCC limits: 10 watts at 33 kHz and 1 watt at 82 kHz and 200 kHz)
In order to demonstrate all available functions, some illustrations depict the 2573-iD 
receiver unit. The 2550 receivers and transmitters may vary from the illustrations  shown.

3. Quick Start
A.  Transmitter Battery Installation
Loosen the six screws on the battery compartment cover on the bottom of the transmitter. 
Remove the cover.
Install six ‘C’ size alkaline cell batteries (LR14) into the compartment as indicated by 
the polarity symbols (+ and –).
Replace the cover and tighten the screws.
Press and hold off [T-1] to manually test the batteries. The display and audio will 
indicate one of the following levels: (OK w/solid tone = good; LO w/beeping tone = 
low; “--” w/no tone = replace)
! CAUTION
To reduce the risks associated with fire and explosion:
•  Do not short, excessively heat, or dispose of batteries in fire.
•  Install batteries with proper polarity.
•  Use only Alkaline “C” (LR14) sized batteries.
•  Do not charge batteries.
•  Do not use leaking batteries.
To reduce the risks associated with environmental contamination:
•   Dispose of batteries and electronic components in accordance with all regulations.
•  Ensure batteries are installed with correct polarity.
•  Always remove batteries when storing the units for long periods of time. 6 ‘C’ size (LR14)
