Claudina StreetAnaheim, CA 92805.1.2 The Sonicator 740The Sonicator 740 is a portable therapeutic ultrasound device from Mettler Electronics Corp.This microprocessor controlled device provides therapeutic ultrasound with enhancedreliability and ease of use. An optional rechargeable battery is available to free the practitionerfrom depending on wall power. The Sonicator 740 automatically self–tunes to the ultrasoundapplicator to ensure accurate delivery of ultrasound.The Sonicator 740 has a standard 5 cm² applicator at 1 and 3.2 MHz. An additional twoapplicators are available. These additional applicators are: 10 cm², 1 MHz and 1 cm², 3.3 MHz.The 5 and 10 cm² applicators are contoured for easy ultrasound application. The pencil–shaped 1 cm² applicator is ideal for delivering ultrasound to hard–to–reach and smalltreatment areas. All applicators attach to the Sonicator 740 using the same universalapplicator cable.The Sonicator 740 produces ultrasound in continuous and 10, 20 and 50% pulsed modes formaximum treatment flexibility. The back-lit liquid crystal display (LCD) informs thepractitioner about treatment status. Time and ultrasound output intensity are activelydisplayed during a treatment. The “ultrasound active” indicator on the display alerts theoperator when ultrasound is being delivered by the applicator. An additional LED on the 5 and10 cm² applicators lights when ultrasound is being delivered and flashes when there is aproblem with coupling.Large controls on the silicone rubber keypad provide one touch entry for treatment parameters.An audible tone provides you with further reinforcement that a selection has been made. Errorconditions are prominently shown on the display as well as all treatment parameters.1.3 Precautions1.The Sonicator 740 operates with high voltages. Servicing should be performed by qualifiedultrasound technicians or the unit should be returned to the factory for service.2.The internal circuit boards are not designed to be serviced at the component level becauseof the extensive use of surface mount circuitry. Any attempt at replacing a surface mountcomponent may result in damage to the board. Replace entire circuit board assembliesonly!7

Mettler Electronics Corp.3.For maximum safety, plug the Sonicator 740 into a grounded wall outlet of proper voltageonly or use the optional battery.
