Congratulations!Youhavejustpurchasedoneofthenest,locatingdevices
available today!
The 3M™Dynatel™Cable/Pipe/ Locators 2250ME and 3M™ Dynatel™ Cable/Pipe/
Fault Locators Series 2273ME are designed with all of the functionality of previous
Dynatelmodels,and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 Cable/Pipe/Fault Locators
2250ME-iD/2273ME-iD 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2250M/2273MSeriestransmittersareavailablein3-watt,5-wattand12-wattunits.
12wattsforthe12-watttransmitter,or5wattsforthe5-watttransmitter,isattainedby
utilizing the Cigarette Lighter Adapter or External Rechargeable Battery (3M Dyntel
Sealed Gel-Cell Battery 2200RB).
3Misdedicatedtobringingyoupremiumequipmentwithoutstandingreliability,backed
by one of the best warranties in the business and outstanding service.

1. Safety Information
Pleaseread,understandandfollowallsafetyinformationcontainedintheseinstructions
prior to the use of the 3M™ Dynatel™ Cable/Pipe/Fault Advanced ME-Series Locator.
Retain these instructions for future reference.
A. Intended Use
The Dynatel Cable/Pipe/Fault Advanced ME-Series Locator is used to identify the
placement of underground utility lines. The system must be installed as specified in
the Dynatel Cable/Pipe/Fault Advanced Locator 2250ME/2273ME Series Operator
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.
FWarning: 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 cables energized with
electrical power. Use appropriate safety procedures.
DO NOT USE ON CABLES CARRYING IN EXCESS OF 600 VOLTS RMS.

6 78-8130-6151-8 Rev G
!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 2200ME Series.
The 2250ME locator is designed for cable/pipe locating. The 2273ME locator is
designed for cable/pipe and fault locating. The 3M iD Marker option (read/write
capability to 3MTM iD Markers) is available for both models. There are three transmitter
options:3Watt,5Watt,or12Watt.Thisinstructionmanualwillincludeallfeatures.All
instructionsareapplicabletoallproducts,unlessnoted.
The 12-watt transmitter option offers additional power output levels for improved
inductionperformanceand8kHz(lowfrequency)inductionforshallowfacilities,such
as risers. Output Power up to 12 Watts for the 12-watt transmitter is achieved using the
supplied external power source.
Inordertodemonstrateallavailablefunctions,theillustrationsdepictthe2273ME-iD
receiver unit and the 2250E and 2273E 12-watt transmitters. The 2250ME receiver 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 re.
• 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.
