Uma inani lamandla esignali u-Q eliboniswe ku-M90 lingaphansi kuka-60, kunconywa izindlela ezilandelayo ukuze uthuthukise:

1) Shintsha indawo engcono.

2) Zama ukupholisha ubuso bangaphandle bepayipi, bese usebenzisa inhlanganisela eyanele yokuhlanganisa ukuze wandise amandla esignali.

3) Lungisa indawo ye-transducer ngokuqondile nangokuqondile; qiniseka ukuthi isikhala se-transducers silingana nenani le-M25.

4) uma izinto zepayipi zingafaneleki ukudluliselwa kwesignali ye-ultrasonic; kutuswa i-transducer yethu yokufaka eneziqongo ezishisayo.
