Intended use
The cable detector is used for fast detection of pairs of wires, cables and lines using the continuity check,
line and polarity test.
Power is supplied by a non-rechargeable/ rechargeable battery (9 V pack) in the receiver and Mignon non-
rechargeable/ rechargeable batteries in the transmitter.
The measuring instrument must not be used when it is open, i.e. with an open battery compartment or when
the battery compartment cover is missing. Measuring under adverse ambient conditions such as dust and
flammable gasses, vapours or solvents is not admissible.
Always observe the safety instructions and all other information included in these operating instructions.

distort the measurement result.
General information on batteries/rechargeable batteries
• Batteries/rechargeable batteries must be kept out of the reach of children.
• Do not leave batteries/rechargeable batteries lying around; there is a risk that they could be swallowed by
children or pets. If they are swallowed, consult a doctor immediately.
• Leaking or damaged non-rechargeable/ rechargeable batteries in contact with the skin can cause acid
burns; therefore, use suitable safety gloves.
• Normal/rechargeable batteries may not be short-circuited, opened or thrown into fire. There is a risk of
explosion.
• Do not recharge normal, non-rechargeable batteries; there is a risk of explosion!
• Please observe correct polarity (note plus/+ and minus/-) when inserting the non-rechargeable/ recharge-
able battery.

Inserting/Replacing the Battery/Rechargeable Battery
1. The POWER LED starts to flash when the charge of the non-rechargeable/ rechargeable battery gets
weak.
You should replace or recharge the non-rechargeable/ rechargeable battery.
2. Loosen the small screw on the transmitter using a screwdriver and then remove the battery compartment
cover “11” carefully.
The battery compartment cover “11” of the recipient is provided with only a small locking lug. Press it
gently upwards and then remove the battery compartment cover “11” carefully using the side handle grip.
3. Remove the empty non-rechargeable/ rechargeable battery from the battery compartment “11” and,
where applicable, insert a new non-rechargeable/ rechargeable battery of the same type (see technical
data) observing the correct polarity. Do not use force.
4. Close the battery compartment cover carefully again.
