Fig. 8: Headphones symbol when the system is ready for use
Left-hand figure: Symbol crossed out, i.e. no measurement in
progress or hearing protection threshold ex -
ceeded during a measurement
Right-hand figure: Symbol not crossed out, i.e. measurement in
progress
If the headphones symbol is crossed out during a
measurement ...
●
The hearing protection threshold has been exceeded during
the measurement. As soon as the noise level falls below the
hearing protection threshold again, the symbol appears without
a cross through it.
●
No measurement is in progress because the measurement
was not started correctly. Check the operating mode setting
for the Activation key. Did you operate the Activation key cor-
rectly?
