!WARNING
To reduce the risks associated with re and explosion:
• Ensure batteries are installed with the correct polarity.
• Do not allow batteries to get wet.
• Only use the supplied charger or purchase a new charger from 3M.
• Only charge batteries in an indoor environment, with a temperature range
of 0o C to 45o C (32oF to 113oF).
• Do not charge Alkaline batteries.
• Use only Alkaline AA (LR 6) with the included holder and adapter.
• Use only Alkaline C (LR 14) sized batteries in the device transmitter.
To reduce the risks associated with re and explosion when using Lithium
Ion batteries:
• Do not operate device outside of -20oC to 50oC (-4oF to 122oF).
• DO NOT DOUSE A BURNING BATTERY! USE A FIRE EXTINGUISHER!
To reduce the risk associated with hazardous voltage:
• Do not attempt to modify, disassemble, or service the device.
• 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.
• 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.
To reduce the risk associated with exposure to chemicals and re:
• Do not open, modify, disassemble, pierce, crack, crush, incinerate, or
expose to heat batteries above 55oC/130oF.
!CAUTION
To reduce the risks associated with environmental contamination:
• Always remove batteries when storing the device for long periods of time.

Quick Start
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)
Installing Alkaline Batteries in the Receiver
Remove cap from receiver handle.
Install eight ‘AA’ size alkaline cell batteries (LR6) into the battery holder as
indicated by the polarity symbols (+ and –).
Attach battery holder to the Alkaline adapter cable and then to the connector in
the receiver handle.
Slide holder into the handle. Replace the cap.
When using Alkaline Batteries it is necessary to use an adapter that has a
protective diode installed in the circuit. If this wire is damaged then call 3M to
get a new adpter. Do not modify this adapter.

Installing Rechargeable Lithium Ion Battery in the Receiver
Remove the receiver cap.
If the Alkaline adapter is connected then remove and connect the Lithium Ion
battery directly to the connector in the receiver handle.
Slide the battery into the handle with text facing left or right of the receiver
handle. Replace the cap.
Receiver Power Up Battery Test
The receiver batteries are tested for two seconds every time the unit is turned
on.
The bar graph on the display will fill to the relative battery level.
The Battery Icon [8] on the Locating Displays will continuously indicate the
battery level.

[T-1] off: Turns unit off and performs battery test.
[T-2] on: Ohm-meter / Tone: Turns the unit on and cycles through the following
commands when pressed repeatedly.
Ohm-meter: Measures the continuity of the trace conductor/pipe and its
far-end ground. It is also used to measure the fault resistance to earth.
[T-3] on: Trace (frequency): Turns the unit on and places the unit in Trace
mode.
Select Frequency: Press Trace [T-3] repeatedly to cycle through the
transmitter’s active frequencies (577 Hz, 8kHz, 33kHz, and 200kHz). The
selected frequency will be displayed [T-4]. ‘ALL' indicates that the following
active frequencies are transmitting simultaneously: 577 Hz, 8kHz, 33kHz,
and 200kHz.
[T-4] Digital Display:
Indicator Flags: These flags coincide with the operational mode of the
transmitter. (From top left to bottom right) Trace mode [T-3], Tone mode
[T-2], Ohm-meter [T-2], Voltage (at start up the transmitter checks for
foreign voltage), and the Output Level Flag (no flag = normal output; flag =
high output).
Digital Display: Indicates frequency, relative current, resistance, battery
level and voltage (if present on target).
[T-5] Output Level: Cycles output level; normal, high and maximum.
Normal=No Flag; High=Flag (indicated in Digital Display [T-4])
NOTE: Output is limited to 3 watts at 577 Hz, 8 kHz, 33 kHz and 1 watt at
200 kHz using the direct connection method.
[T-6] Output Jack: Port for direct connect cables or Dyna-coupler.
