Note this means that when using a more narrow Signal
Focus Control setting, it is necessary to move the re-
ceiver along the line more slowly. This is a trade-off
for the improved focus, and will avoid missing data up-
dates at the slower rate.
When it is selected on, the Signal Focus Control is
changed to narrower or wider settings using the Up (nar-
rower) and Down (wider) Keys.
Signal Focus Control is useful when you need to focus
in on a particular signal with detail.
Sound Muting
This option enables the automatic muting of the sound
when the Measured Depth is greater than the setting of
the Proximity Threshold setting. If the Proximity Threshold
is not selected on, this option automatically mutes sound
when Measured Depth is greater than 99 feet (30m). If it
is unchecked, the sound will not mute automatically.
Tracing Line Response
The Tracing Line distortion response checkbox sets the
sensitivity of the Target Line's distortion display to low,
medium, or high – or disables it altogether. The higher the
setting, the more sensitive the "distortion cloud" around the
Tracing Line becomes.
If the distortion response is disabled, the Tracing Line will
become a single solid line, and the screen will show a sec-
ond, dashed, line called the Distortion Line. (See page 26
for a description of using this alternative display.)

Frequencies Selection Control

Additional available frequencies on the Master Frequency
Menu can be added to the Main Menu list of available fre-
quencies by going to the Frequency Selection Control sub-
menu and selecting the desired mode. All
frequencies available in the SR-20 for that mode will be
displayed. Checked frequencies are already "Currently
Available" – that is, selected to appear in the Main Menu.
From there, they can be set to "Checked-Active" status to
make them available by use of the Frequency Key.
To select additional frequencies, highlight and select
the Frequency Selection sub-menu. Highlight the
Ridge Tool Company

category of the desired frequency (Figure 43). Press the
Select Key .

Then use the Up and Down Keys to scroll through the

add it to the currently available list (Figure 44).

Checking a frequency (using the Select Key) will enable
it to be included in the "Currently Available" list of fre-
quencies on the Main Menu (Figure 45). Once on the
Main Menu, it can be set to "Checked- Active" status,
and then be put into use using the Frequency Key
