„ If no indicator lights, replace the batteries (see §4.2). If the 

problem persists with new batteries, the device is defective 
and must be sent in for repair (see §4.4).

After each check, perform a self-test in order to confirm the 
proper operation of the device.

In a noisy environment, make sure that you can in fact hear 
the audible signal emitted by the device.

Remark:  If the AUTO TEST button is kept pressed for 

more than 10 seconds when the test probes are 
not touching each other, the device switches to 
standby.

Connect the red test probe to the 

+ terminal and the black 

lead to the 

COM terminal.

Keep your hands behind the guards of the device and of 
the test probe.

Place the test probes on the element to be tested and main-
tain a firm contact.

There is no need to switch the C.A 740N on, because it starts 
up automatically.
