CAMERA LOCATION
1. Turn on Gen-Eye Camera system.
2. Press and hold the Hot Spot Locator
On/Off button. Check battery strength
on display.
3. Press MODE icon until indicator dis-
plays Sonde/Camera Head mode.
4. Press Antenna Select icon until indica-
tor displays Total Field configuration.
5. Set Locator to 512Hz by pressing
FREQ button until 512 Hz appears on
display.
6. Press up arrow button to increase
GAIN to maximum sensitivity.
7. Push camera head/Sonde only 10 to
15 feet into the line before starting the location process.
8. Stand near pipe entrance and hold the Gen-Eye Hot Spot Loca-
tor so that the blade is pointed at 45 degree angle, out and
down towards the ground at the approximate distance of the
transmitter.
9. Rotate in a circle, listening to the signal strength indicator tone.
If you receive full signal strength in every direction, press and
release the DOWN ARROW button to reduce the GAIN, or sen-
sitivity of the device. Repeat process until you receive a strong-
steady tone from just one direction. Reduce gain further if nec-
essary to clarify exact direction.
10. Hold Hot Spot Locator blade perpendicular to the ground and
walk in the direction of the strongest signal.
11. As you walk, reduce gain by pressing and releasing down arrow
button as often as necessary to keep signal strength indicator
near the 50% level. (Signal Strength levels in the 100% range
will erode accuracy. Always aim to keep the signal strength
near 50%.)
12. The radio waves propagating from the transmitter look like this:
Locator
Null
Notice that there is a PEAK signal over the exact location of the
transmitter, and two NULL points on either side of the PEAK,
lined up parallel with the lay of pipe.

13. Watch the Gen-Eye Hot Spot monitor display as you approach
the transmitter's location.
14. When you reach the vicinity of a NULL point the screen will
produce this display:
Simply follow the arrows to find the exact spot. When you are
over the NULL point, the screen will produce this display.
15. When you reach the vicinity of the PEAK the screen will pro-
duce this display:
Follow the arrow to pinpoint the location of the transmitter.
Simply rotate the flat edge of the locator blade relative to the
arrows on the outside of the 'compass' to determine the orienta-
tion of the transmitter. When the display shows this graphic:
you will have the exact location of the transmitter and the lay of
the pipe.
16. Find and mark the location of both the NULL and the PEAK
points.
17. Push the camera ahead another 10-20 feet and repeat the pro-
cess. Duplicate every 10-20 feet until the problem area is visible
on the Gen-Eye monitor. At the completion of this process the
entire line will be traced and marked.
