Listening to noise with the F54
headphones
Preparing the headphones for operation4.1
To be able to listen to noise with the F5 wire-

tinue listening to noise.
When both the F5 headphones and the

with SDR is switched on within the range, it
will not affect the radio connection between
the two components.

nection between the F5 headphones and the
SEWERIN device, the F5 headphones will go
mute. You will no longer hear any noise. Once
you move back into the reception radius, you
will hear noise again. 22
