Connect the cable terminals to the sender's RJ11
connection and to the required line, and switch
the sender to SCAN mode. Press the MODE
button (3) until the SCAN mode LED (7) lights
and the SCAN status LED (6) flashes. Then use
the receiver to search for the line, with the test
mode button (21) held down (see Fig. a). To
achieve the maximum measuring depth, set the
receiver signal volume as high as it will go (18).
Tip 2: Depending on the application concerned, it may be advisable to change the type of signal. In SCAN
mode keep the MODE button (3) pressed until the SCAN status LED (6) lights continuously. The signal type
is reset by briefly pressing the MODE button (3). The SCAN status LED (6) flashing indicates a modulated
signal; if it lights continuously this indicates a constant signal.

Locating network, telephone and multimedia cables, and individual wires
Connect the adapter cable or cable to be located to the sender and switch the device to SCAN mode. If
necessary, connect the sender to a network or telephone socket (see Fig. b). For measurements using the
cable terminals, connect the red terminal to the cable to be located and connect the black one to earth
(earthing conductor or shielding). Then use the receiver to search for the connected cable. See also Tip 2.

The lead transmission signal that is fed in may be transmitted to other cables if they are parallel
to the lead over longer distances.
Tip 3: To locate the cable more efficiently, gradually reduce the receiver signal volume using the control
(18). The cable can be located by means of volume differences and is indicated by the status LED (19)
lighting up at its brightest or by the maximum signal volume.
Tip 4: The best search results are achieved when the test prod (15) has a direct metallic contact with the
cable being located. This type of contact will produce a clearly audible jump in the signal. You can also get
stronger signals at the cable ends (Fig. c) or directly at the individual wires (Fig. d).
Tip 5: Any interference that occurs (buzzing, etc.) can be reduced by earthing the return conductor or
shielding conductor in the test lead. Earthing by means of your own hand or finger may be enough,
however.
