Hi @delson89820

Here's the [document|39987|service manual] for the unit that may help.

Go to p.6-17 (195 of 440 pdf) and check if audio is heard when simulating the Ultrasound. Ultrasound audio volume from the rear panel speaker can be increased or decreased using the left pair of Volume push buttons.
