High Power Output
High Power Output is a feature on UtiliGuard T12 and T12+ units. It allows the operator to transmit 12
watts on an active line at less than 10kHz and below. Use this function on large diameter direct buried steel
pipe and long distance locates.
To activate:
1. Navigate the transmitter menu to Settings>Output>High Power.
2. Select “Enable” or set timer as desired.
Mark the Cable
Sweep, focus, and trace all detected signals in the area. Mark cable paths with colored paint or flags. See
the chart below for standard color markings for cable locations.
Special Situations
NOTICE: When using high power output, either install a Lithium ion battery pack or connect the
transmitter to an external power source.
Utility Color Marking Symbol

Situation What to try
Signal is lost. Walk in a circle to detect a tee or bend in the cable.
Signal varies from low to high and is
unstable. Mark as a hand-dig area.
You are near a power line and are
receiving interference. Sweep the area in 50 Hz or 60 Hz power mode. If receiver
gives a strong signal response, a power line is interfering
with transmitter signal.
Receiver does not function properly. Receiver gain could be set too high or low. Lower or raise
gain to locate the cable. See “Controls” on page 15.
Target cable has connections to other
cables. Disconnect target cable from other cables or use direct
connect or induction clamp to focus signal on target cable.
