Vox -01 Operating Manual page 35

The new calibration factor (sensitivity adjust) of the device is shown, as well as the original
calibration factor as currently used in the device. The differences between the old and new
value are typically small (less than one dB), unless you have connected a different signal
source or microphone than the device is currently calibrated for.
The calibration factor is derived from the measured LAeq, as well as the reference level of
your calibration signal source. You can now change the reference signal level; press the cor-
responding button on the right of the screen, and enter the correct value. The calibration
factor will be re-calculated.
If you are satisfied that the new calibration factor is correct, press save. Note that the new
calibration settings only take effect once you press save.
We recommend that you verify your new calibration in the SPL meter app. Re-apply your
calibration signal source, and check that the correct reference level is measured.
Once you press "save", the measured calibration factor is committed perma-
nently to the device's non-volatile memory. This overrides earlier calibrations.
