The Induction Peak mode of the receiver is a mode in which the upper antenna of the
receiver is tuned to minimize distortion from the magnetic field of the transmitter.
Left or Right of Target Path Directly Over Target Path

In Directional Peak mode, four peak antennas are used to analyze the magnetic field
pattern. The bar graph indicates signal strength and the directional arrows sense the
edges of the magnetic field. The left/right arrows will indicate the direction to the nearest
cable/pipe that is in-line with the receiver handle.
As the antenna crosses the cable or pipe, the receiver speaker volume increases to a
maximum, the Bar Graph [1l] ([10] for 2550 locator) fills from both sides toward the
middle, and the numeric Signal Strength [9] ([8] for 2550 locator) increases. As the
antenna moves off the target path, the speaker volume decreases and the Bar Graph [1l]
([10] for 2550 locator) opens. Use the Bar Graph [1l] ([10] for 2550 locator) and the
numeric Signal Strength [9] ([8] for 2550 locator) to locate the exact target path.
Left of Target Path Directly Over Target Path Right of Target Path
Once the target path has been located, the arrows at the top of the display will indicate
the location of the target path in relationship to the receiver handle.
Note: When field distortion (due to congestion) is affecting the receiver, the left/right
arrows may not coincide with the bar graph. Use the maximum numerical Signal
Strength [9] ([8] for 2550 locator) to target the cable or pipe.
