1. Safety Information
Pleaseread,understandandfollowallsafetyinformationcontainedintheseinstructions
priortotheuseofthe3MCable/Pipe/FaultAdvancedM-SeriesLocator.Retainthese
instructionsforfuturereference.
A. Intended Use
The3MCable/Pipe/FaultAdvancedM-SeriesLocatorisusedtoidentifytheplacement
ofundergroundutilitylines.Thesystemmustbeinstalledasspecifiedinthe3MCable/
Pipe/FaultAdvancedLocator2250M/2273M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.
m WARNING
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
m Warning: Indicates hazardous situation which if not avoided, could result in
death or serious injury.
m 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
m 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.

78-8130-6150-0-F 7
m 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2200MSeries.The
2250Misdesignedforcable/pipelocating.The2273Misdesignedforcable/pipeand

m WARNING
To reduce the risk associated with hazardous voltage:
• Potential for electric shock exists when handling connection cables while the transmitter is
ON. Make all connections prior to powering on the unit. Turn transmitter OFF before handling
connection cables.
• Voltage greater than 240 volts will damage equipment and could cause personal injury or
death. Make all connections before turning on the transmitter. Follow standard procedures
for reducing the voltage.
• Do not change or modify this product in any way.
H. Rechargeable Battery
The3MDynatelSealedGel-CellBattery
2200RBcanbeusedasanauxiliarybatteryin
3M™Dynatel™2200SeriesTransmitters.Itplugs
intotheExternal Jack[T-7]andprovidespower
forthetransmitter.Whentherechargeablebattery
ispluggedin,normaloutput,highoutput,and
maximumoutputareavailable.Whenthe
rechargeablebatteryisconnectedtothe
transmitter,thealkalinebatteriesarebypassed.
Therechargeablebatteryisaleadacidbattery
ratedat5.4amp-hoursandisequippedwithauserreplaceablefuse(5A/32V).
Note: The internal batteries must be at least 5.4 volts. Do not remove the alkaline
batteries from the transmitter when using the rechargeable battery. Rechargeable
battery, or cigarette lighter adapter cable, is required for Maximum output level.
Rechargeable battery is shown installed in the well of the transmitter case.
