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.

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.

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
