Avoid placing the Transmitter over metallic manhole covers as this will severely reduce the effectiveness of the
Transmitter, and in extreme cases, cause damage to the Transmitter's circuitry.
1. Turn the Transmitter on by pressing the power button for two seconds.
2. Place the Transmitter over the suspected location of the line, positioning it so that it is perpendicular to the line.
3. Press the Signal button to switch between Hi and Lo signal strength. Lo signal level uses less energy and helps to
preserve batteries. Increase the level if the resulting signal strength is poor. Increasing the signal unnecessarily may
result in the signal being induced into unwanted lines.
Induction Mode – Locating with the Receiver
1. Turn the Receiver on by pressing the power button for two
seconds.
2. Press " " button repeatedly until 33 kHz is selected.*
3. Follow the steps as described in the Receiver Locating
section 3.1, using the Left/Right arrow indicators to quickly
assess location of the wire.
4. Optionally measure the depth of the wire. Refer to the Taking
Depth and Current Measurements section 4.3
for details.
For better accuracy, after the initial location of a utility is detected,
move the Transmitter directly over it in case it was not placed
precisely in the beginning of the search.
Where the signal is distorted, the arrows may indicate a different target position than the largest bar graph reading. In
this situation, always use the bar graph to pinpoint the line as it is influenced less than the Left/Right arrows in a
distorted signal field.
* 8 kHz frequency is not used for connection with UAT-500-T Transmitter. This frequency is provided to support
optional UAT-600-T Transmitter.
