Make sure before starting up operation that the device is suitable for the purpose of use for which it is to be used. Inserting/replacing batteries A 9-V compound battery is required for operation (not included in the scope of delivery). Open the battery compartments (7 and 19) on the back of the two devices, connect the battery clip paying attention to the polarity of the battery and close the compartment again with care. Replace the battery if, after some period of operation, the undervolt- age LEDs (LOW BATT 13/17) appear. To do this, proceed as follows: disconnect the corresponding devices from all connected cables. open the battery compartment (7/9). remove the flat batteries and insert an unused battery of the same type paying attention to the polarity.

Use only alkaline 9-V compound batteries. These are more efficient and afford a longer operating period than the conventional zinc-carbon batteries. Close the battery compartment lid after inserting the battery correctly. Incorrect polarity of the battery will lead inevitably to destruction of the device! 28Net toner (16) Voltage source for voice connection The net toner can be used as the source of voltage for voice con- nections for test purposes. Make sure before connection that the cables are not alive (danger to life).

• Turn the switch-over (22) after the end of the test to the central position "OFF" again. 33Net probe (1) Cable tracing / identification The test signal which is transmitted from the bet toner can be received using the net probe. The signal received is reproduced on the built-in loudspeaker (8). In a loud environment, an optional mono-earphone with a 2.5-mm jack plug can be connected to the net probe (jack 5). To activate this output, switch the slide switch (3) to the position "EAR". Do not use the net probe on cable on which voltages greater than 24V AC / 48 VDC are or could be existent (danger to life!). Make sure of this before commencing the test. 34To trace the signal, proceed as follows.

• Slide the mode switch (14) on the side to the "TRACE" position for signal tracing.

• Press the test key (9) and the net probe will be activated. Hold this pressed down during the cable tracing.

• Signalisation takes place optically over the signal display (11) and acoustically over the loudspeaker (8)

• Now set the desired signal volume on the volume control (10).

• Guide the test tip (2) beginning with the signal transmitter (16) parallel to the course of the cable. The volume must remain con- stant if the cable tracing is correct

• If you wish to identify a certain cable end, you can select from three test possibilities.

1. Search without contact with the test tip (2)

2. Contact-search through the RJ45 jack (4) at the side

3. Contact-search through contacts (6) at the back

Cable test for analogue telephone cables Analogue telephone cables can also be checked for their condition on the net probe. The status is displayed over two light diodes. Do not use the net probe on cables on which voltages greater than 24V AC / 48 VDC are or could be existent (danger to life!). Make sure of this before commencing the test. 35Proceed as follows for the cable test:

• Slide the switch (14) on the side to the "TEL" position for signal the telephone cable test.
