Sensitivity of the learning function
Enter the access code (see page

If Shuttle ® periodically is locked on a false echo, even if the
learning function has been activated (see page 28 ), it may be
necessary to increase the sensitivity of the acoustic image
that was stored in Shuttle
® during the learning process.
On the contrary, under rare occasions it may be necessary
to decrease the sensitivity under particular acoustic occa-
sions, where double echos may occur that causes Shuttle
®
to lock.
