: Often an unmarked NPN transistor. Common successful replacements include the , , or .
: It is dangerous to put hands in the water while an ultrasonic device is active, as it may damage small blood vessels (capillaries).
: A red LED (HL1) protected by a diode (VD1) indicates the generator is operational. Operational Highlights Efficiency : The : Often an unmarked NPN transistor
: The device typically utilizes a classical inductive three-point oscillator (inductive Hartley oscillator) to drive the piezoelectric element.

: If the power indicator is on but no ultrasonic waves are visible, it usually points to a burned-out transducer or a generator fault .
Retona USU-0707 " is a compact ultrasonic washing device consisting of a power supply unit and a small piezoceramic radiator (activator). The device works by emitting ultrasonic waves into water to dislodge dirt from fabric fibers. машина РЕТОНА УСУ-0707
model was designed with an increased power consumption (from 9W to 30W in some iterations) to improve the efficiency of the ultrasonic emission into the liquid.
