7. RADIO MODE

The .passive .Radio .Mode .employs .only .the .
PL-2000 .Receiver .and .the .ambient .radio .
signals .emanating .from .power .lines, .radio .
stations, .and .other .low .frequency .radio .
communications . .These .radio .signals .are .
present .all .over .the .earth .and .they .often .
energize .long .pipelines, .such .as .water .and .
gas .lines . .
Radio Station.
1 . . .Press .the .Frequency .Select .key .(2) .until .
"Radio" .is .displayed .on .the .receiver's .
screen . .
2 . . .At .the .Operating .Mode .key .(3), .choose .
the ."Peak" .Mode . .The .Radio .Mode .only .
works .with ."Peak" .Mode . .
3 . . Increase .or .decrease .the .Sensitivity .(4) .
with .the .up/down .arrow .keys .until .the .
"signal .pyramid" .appears .as .two .bars .on .
the .pyramid .sides .
NOTE: . The .DEPTH .function .is .not .available .
in .Radio .Mode .

8. SONDE MODE

The .Sonde .Mode .is .useful .for .locating .non-
metallic .pipelines, .like .PVC .or .asbestos/ce-
ment .sewer .pipes, .clay .pipes, .concrete, .etc ., .
that .do .not .have .a ."tracer .wire ." . A ."Sonde" .is .
a .small .battery .powered .transmitter .that .can .
be attached to a sewer "snake," other flex-
ible rod, or a "PIG," and pushed, or flushed
through .the .pipe .with .a .string .attached .to .it . .
Check .the .particular .Sonde .and .PL-2000 .
Receiver together first outside of the pipe
on the ground. Confirm that the Receiver
is .detecting .the .Sonde .and .measuring .its .
depth .correctly . .
1 . . .Turn .ON .the .PL-2000 .Receiver .and .
press .the .Operating .Mode .key .until .a .
small .Sonde .appears .in .the .upper .left .
corner .of .the .display . .
.
8 kHz Sonde.
2 . . .At .the .Frequency .Selection .Key, .choose .
27 .kHz, .8 .kHz, .or .a . .5 .kHz, .depending .
upon .the .frequency .transmitted .by .the .
Sonde . .
3 . . .Turn .ON .the .Sonde .and .lay .it .on .its .
side . .The .PL-2000 .receiver .detects .the .
Sonde .from .the .side .of .the .Sonde . .When .
the .Sonde .moves .through .the .pipe, .the .
ON
receiver .is .faced .parallel .to .the .pipe .(and .
the .Sonde) .and .not .in .the .direction .of .the .
LED
pipe .(90 .degrees .from .normal .operation) .
OFF
4 . . .A .Sonde .makes .3 .peaks: . A .large .one .
Detectable
directly .over .it .and .two ."false" .peaks, .one .
Depth:
off .each .end .of .the .Sonde .
15 feet.
