DANGER!
Check for stray voltages before attaching transmitter.
Voltage greater than 240 volts will damage equipment and
cause personal injury and death. Follow standard
procedures for reducing the voltage.
1. With the transmitter off, plug the direct connect
cable into the transmitter front panel jack.
2. Connect the black clip to the ground rod.
3. Place the ground rod in the earth as far from the near
end connection as the leads will allow, at a 90–
degree angle to the suspected cable path.
4. Remove the near-end shield bond; connect the red
clip to the shield.

1. Hold down for Battery Test (solid tone=good;
beeping tone=low; no tone=replace batteries).
2. Press
to turn the unit on and select Continuity
Test
(solid tone=good ground; beeping tone=
usable ground; no tone=poor ground or no far end
ground). Both LEDs light continuously during the
continuity test.
3. Press
to apply Tracing Tone and select the
desired frequency: 577 Hz for direct connect with
far end ground; or 33 KHz for direct connect with no
far end ground, or for use with coupler, or induction.
LED indicates frequency selection. (This key can also
turn the unit on.)
4. Press
to change output level. Choose Normal
output (flashing LED) for locating short to
moderate distances using direct connect method. Use
High output (solid LED) for coupler, induction, or
direct connect for long distances and deep cables.
5. When locating is complete, press
to turn the
unit off.
