Display Elements Menu
Advanced features of the SR-20 can be enabled by
using the Menu Key to show the menu tree. Select the
Display Elements selection menu. Then select the mode
(Line Trace or Sonde) you want to change.
Selecting the icon representing two small display screens
will bring up the Display Elements Menu for either
or Sonde mode. The SR-20 is shipped with some of
the elements switched off for simplicity. To toggle an ele-
ment on or off, press the Up or Down Key to highlight the
screen element icon for that feature. Then use the Select
Key to check or uncheck the box. Checked display ele-
ments are selected to be on for that mode.

Optional Features

Optional Features in the Display Elements Menu include:
Race Track and Watermark
The "Race Track" is a circular track around the center of
the Active View Area on the screen. The Watermark is a
marker which appears in the outer ring of the display, trav-
eling along the Race Track (Figure 39). The Watermark is
a graphic representation of the highest Signal Strength
reached (in Sonde mode) or the highest Proximity Signal
level reached (in Line Tracing modes). It is "chased" by a
solid Level Pointer which shows the current Signal
Strength.
This provides an additional, visual way to track the max-
imum signal. If you are trying to trace a line by noticing its
highest Signal Strength level, the Watermark serves as a
visual aid.

No-Signal Icon (Suppression)
When the SR-20 is not receiving any meaningful signal
on the selected frequency it will display the mode sign
with a line through it, indicating no signal is being de-
tected (Figure 40). This reduces the confusion of trying
to interpret the random noise that some locators display
in the absence of a signal.
• Depth suppression – If the Measured Depth is greater
than the threshold depth (by default, 99'/30m in Sonde
mode and 30'/10m in Line Trace mode), the map is
suppressed. (In Line Trace mode, the Proximity Thres-
hold control may be used to change the threshold
depth setting).
• Noise suppression – If the signal is seen to be too
noisy, the map may also be suppressed.
