Note: Key descriptions can be found on the side of the Receiver.

Press to turn the Receiver on.

Press to select the 50/60 Hz power frequency (see Selecting Passive Power Frequencies, page 12) or LF for passive locating; otherwise, select the same frequency as the Transmitter.

Note: The Receiver is automatically set to Special Peak mode when LF is selected. No other modes are allowed in LF frequency.

Press to adjust the speaker volume as needed: off, normal, high, or high-expanded. The high-expanded setting causes the audio to cut off below a certain threshold.

Press to select a locate mode (Peak , Null , or Diff ).

To select Special Peak mode: from Peak mode, press and hold then

press to toggle between Peak and Special Peak modes. While in Special Peak mode, the peak flag will flash.

Note: Peak, Special Peak or Null mode may require re-setting the Receiver

gain. Press when the bar graph remains either fully open or fully closed. This is not necessary in differential mode since the unit automatically adjusts the receiver gain.
