TW-82P RECEIVER
Audio: When you move within a 45º angle of the center of the
electromagnetic field, the audio pitch will change; the pitch
increases as you approach the utility. Outside the 45º zone, the
pitch does not change.
When the Receiver is directly over the utility, it goes silent. The over-
target indicator,
•
, also appears when the Receiver is directly over
the utility.

When you are standing to the right of the utility, you will hear
a constant tone, and to the left, a pulsating sound.
3. Azimuth:
These rotational arrows indicate the utility’s path
relative to your position. The arrows will point in the direction of
the utility’s path as the Receiver is
rotated near a burried utility.

4. Current Measure:
mA (milliamperes) of current
flowing on the conductor.
Use Current Measure as an aid
for distinguishing utilities in close
proximity. The Current Measure
will generally be the highest on the
utility you are connected directly to,
regardless of the utility’s depth
