6. Stop the measurement when the current value for the meas-
ured sound velocity has stabilised.
7. Apply the measured sound velocity by pressing
Confirm
.
The sound velocity measurement is complete. The receiv-
er will switch back to the
Correlation
menu. The measured
sound velocity is applied to the current measurement.

Listening to noises
Note:
F8
wireless headphones are required for listening to noises.
3.7.1
Information about the radio connection during listening
The
C 200
receiver and
F8
wireless headphones communicate
by bidirectional SDR (SDR: Sewerin Digital Radio).
SDR transmits uncompressed signals in real time. Radio inter-
ference can, therefore, cause a short clicking noise in the head-
phones.
SDR uses the same frequency ranges as, for example, WLAN
or Bluetooth. In rare cases, SDR can, therefore, be affected by
other radio connections.
These effects can be minimised by the following measures:
●
Avoid drops in the SDR radio connection caused by obstruc-
tions, e.g. your own body. Carry the receiver in such a way
that the transmission path to the headphones is not obscured.
●
If you are carrying electronic devices that use WLAN and Blue-
tooth directly on your body: Disable the WLAN and Bluetooth
function if necessary.
