• ALPHANUMERIC DISPLAY - The alphanumeric display is used to display signal
strength and depth. The numeric display is also used for temporary indications of
certain operating modes, frequencies, and other brief information messages, as noted
throughout this manual.
o Signal Strength - This is an indication of the relative signal level detected by the
receiver and is a function of the gain setting. Good signal strength will typically be
between 200 and 800.
The display range for signal strength is 0 to 999; however, very high signal strength
is not necessarily better. If readings of 995 or higher are consistent, the signal is
too strong and steps should be taken to reduce it. If a reading of “OL” is observed,
a signal is present which interferes with the signal the receiver is set to detect.
Steps should be taken to identify the source of interference or to change the locating
mode.
o Depth Reading – When measuring depth, the “depth” icon lights up
in the lower right of the display, and the depth of the target is
displayed (in feet and inches, or meters - depending on the factory
setting). The display range for depth in feet and inches is 0" to 19’ 9"
and in meters is 0.00 m to 5.99 m.
• VOLUME INDICATOR - The volume indicator consists of a speaker
symbol with 3 sound wave bars. If the volume is off, the speaker
symbol with NO bars is shown, for medium volume the speaker symbol
with 2 bars is shown and for maximum volume the speaker symbol with
3 bars is shown.
The speaker produces an audible indication of signal strength. The pitch of the sound
will increase with increasing signal strength. However, the volume is determined
only by the VOLUME control, as explained above.
