Page 16: Receiver Modes
Receiver Modes Directional Peak (DirPk) [SK Toggle] In DirPk 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 that is in-line with the receiver handle. - Page 17 receiver speaker volume decreases. As the antenna moves off the target path, the bar graph opens, the signal strength increases, and the speaker volume increases. Gain adjust is automatic in DirNull mode. The center of the DirNull screen provides a ‘compass view’ of the target path.
