Intended Use

Intended Use

The Gen-Eye Hot Spot receiver is designed to locate buried pipes and cables. Twelve frequencies and four
modes of operation are available to suit your specific locating needs.

The Gen-Eye Hot Spot transmitter places a signal on target cables to be detected by Gen-Eye Hot Spot
receiver. The signal is placed through either direct connection, induction clamping, or broadcast mode.

The system is designed for operation in temperatures typically experienced in earth moving and
construction work environments. Use in any other way is considered contrary to the intended use. The
Gen-Eye Hot Spot system should be operated only by persons familiar with its particular characteristics
and acquainted with the relevant safety procedures. The system should be serviced only by authorized
repair centers.

IEC Safety Definitions

Hazardous voltage--electrical shock or equipment damage can result if transmitter is connected to
live cable. Have qualified utility personnel disconnect both ends of cable before working.

IEC protection class II or double insulated electrical device is one which has been designed in such
a way that it does not require a safety connection to electrical ground. In a device of this class, no
single failure can result in dangerous voltage becoming exposed so that it might cause an electrical
shock. This characteristic must be achieved without relying on a grounded metal casing.

diamond (1) will form in the center of the
compass, the exterior arrows (2) will appear,
and the depth reading will display.

7. If operating in Manual depth, press the Depth
key to estimate depth.

NOTICE: When estimating depth with
a beacon in nonmetallic pipe, depth
shown will be to the center of the
beacon, not to the top of the pipe.

8. Continue to track the beacon and observe
depth readings. Mark pipe location with paint.

Common Signal Problems

Common Signal Problems

Distortions in the electromagnetic field around a cable can affect location accuracy. Tees, bends, parallel
cables, crossing cables, or large metallic objects can distort signals.

IMPORTANT: If target depth and location are critical, confirm by hand-digging or vacuum excavation.

Learn to recognize the following kinds of distortion:

Shadows

Shadows, also called blind spots, often happen when a metallic object partially obstructs the signal, or a
signal from a parallel cable interferes with target signal.

Secondary (Ghost) Signals

A typical beacon signal pattern shows a main signal and two weaker secondary signals. Identify beacon
location at the main signal. Familiarity with beacon signal patterns will lessen the effect of ghost signals.
Using the Total Field antenna mode will eliminate ghost signals. See “Select Antenna Configuration” on
page 27.
