4.2 Fastening on a mounting surface

While pressing the latch (4) in the base of the device (Fig. 6,
left) pull out the transducer securing brackets (1). To return
the brackets to their original positions, the latch (5) in the base
of the device has to be depressed before applying pressure
to the securing brackets (1) (see Fig. 6, right).
