Uma inani lamandla esignali Q eliboniswe ku-M90 lingaphansi kuka-60, izindlela ezilandelayo zinconywa ukuba zibe ngcono:

1) Hambisa indawo engcono.

2) Zama ukupholisha indawo engaphandle yepayipi, futhi usebenzise inhlanganisela eyanele yokuhlanganisa ukuze ukhulise amandla esignali.

3) Lungisa ukuma kwe-transducer ngokuqondile nangokuvundlile;qiniseka ukuthi isikhala sama-transducer siyefana nenani le-M25.

4) lapho impahla yepayipi ingafaneleki ukuhanjiswa kwesignali ye-ultrasonic;i-transducer yethu efakwe phezulu eshisayo iyanconywa.
