0:00connection. You can trace the water mane by directly connecting to the hydrant. In the same way, the gas can be traced using either a siphon or an upright or directly connecting to a steel service. Another way of inducing a signal into a cable, such as a sky dish cable, is to wind the red lead around the cable or shroud and then clip the crocodile clip back onto itself. This will send a signal through the low voltage system in the house and out through the electricity service. This is known as signal jumping. When using signal jumping, press the boost button on the Genny as this will

The most common earth is a spike method. This should be gently pushed into the ground at a 45° angle only after a cat survey of the area has been carried out. Switch the Genny on and a good earth connection is indicated by a drop in the loudspeaker tone. Please take care not to create a trip hazard with the earth cable. If the CAT appears to be over sensitive, try to slowly withdraw the
