Sonde Mode
Use Sonde Mode to locate a sonde that is inside a pipe,
conduit, or tunnel�
Sonde Mode Frequencies
Default
Preprogrammed
User Programmable
Note: Sonde Mode and Line Trace Mode
sometimes use the same frequency. Make sure the
mode icon next to the frequency that you are using is
the mode you intend to be locating with. Depth mea-
surements will be in error if the incorrect mode is used.
User Programmable Custom Frequencies
The SR‑24 comes preprogrammed with a selection of
frequencies that are set by default in Active Line Trace
Mode, Passive Line Trace Mode, and Sonde Mode� You
can also create custom frequencies to use the SR‑24
with transmitters from most manufacturers�
Note: Refer to the Custom Frequencies section for more
information.

Volume Control
To increase and decrease the volume level of the SR‑24's
audio cues, first press the Volume Key
either press the Volume Key to cycle through volume set‑
tings, or press the Volume Key
and Down Arrow Keys
tings� Press the Select Key
screen�
In all modes, if the sound level reaches its maxi‑
mum frequency range (pitch), it rescales to the mid‑
dle of its frequency range� The modulation of fre‑
quency is used to indicate signal strength�
Line Trace Modes
The SR‑24 emits sounds related to the estimated posi‑
tion of the utility� If the utility's estimated position is on the
left side of the receiver, you will hear a warbling sound�
If the utility's estimated position is on the right side of
the receiver, you will hear the same warbling sound plus
short clicks�
In Active Line Trace Mode and Passive Line Trace Mode,
the SR‑24 emits a higher pitch as it approaches the tar‑
get� The rising pitch indicates an increasingly strong
Signal Strength�
When local conditions distort the shape of the signal
field, the Tracing Line is fuzzy and the audio contains
static� The degree of fuzziness and the amount of static
in the audio reflect the amount of distortion detected in
the signal field�
Sonde Mode
In Sonde Mode the pitch rises and falls relative to chang‑
es in the Signal Strength� As the SR‑24 moves away from
the sonde, the pitch falls� As the SR‑24 moves closer to
the sonde, the pitch rises�
