Section 1:
Introduction
1.1 Introduction to the Sonicator Plus 930 Thank you for purchasing the Sonicator Plus 930 two-channel combination unit for therapeutic ultrasound and muscle stimulation. The microprocessor controlled Sonicator Plus 930 provides interferential, premodulated and medium frequency waveforms with enhanced reliability and ease of use. In addition the Sonicator Plus 930 offers 1 and 3 MHz ultrasound using a dual frequency 5 cm² applicator. An additional two applicators are also available: 1 Mhz, 10 cm² and 3 Mhz, 1 cm². The Sonicator Plus 930 must be specially calibrated to use these applicators so that they function properly. The two–channel Sonicator Plus 930 allows you to utilize up to two different waveforms using two channels simultaneously. You can choose between several different amplitude modulation options such as the surge, reciprocation and vector rotation. The interferential and premodulated modes offer frequency modulation as well as a static frequency option.
Figure 1.1- Sonicator Plus 930 The membrane panel provides both tactile and audio feedback when buttons are pressed. Blinking LED’s guide you through the easy setup routine. The Sonicator Plus 930 features new “Reset” and separate “Enter” keys to make programming your treatment setups easier. Large, soft-touch control knobs make adjusting power for ultrasound and stimulation easy to accomplish with no guesswork involved. Two LED output displays allow you to monitor two channels simultaneously for two channel or combination treatment protocols. These also allow you to adjust both channels of an interferential protocol simultaneously while monitoring the current. 5

Section 3-Installation 3.1 Installation Instructions 1. Connect the line cord to the back of the Sonicator Plus 930. (See Figure 3.1) 2. Plug the line cord (ME 7293) into a grounded wall outlet that is rated between 90–240 VAC, 50–60 Hz. Your power supply must match the voltage requirements listed on the serial number label of your device. Do not connect the Sonicator Plus 930 to a power supply rated differently than that described above. 3. The line cord comes equipped with a standard 3–prong plug. This plug provides grounding for the Sonicator Plus 930. Do not defeat its purpose by using 3–to–2 prong adapters or any other means of attaching to a wall outlet. 4. Push the hooded, water-proof applicator cable connector (ME 7392) into the round BNC receptacle located on the front of the Sonicator Plus 930. (See Figure 3.2) Connect the applicator model 7513 to universal applicator cable using the BNC connector. (See Figure 3.3). Secure both connectors by lining up the pegs, pushing in all the way and rotating ¼ turn clockwise. To maintain waterproof characteristics of the BNC connectors make sure that all connections are dry before attempting to connect them. 5. Place the applicator into the applicator cradle. 6. Plug the electrode cables (ME 2260) into the electrode cable connections as seen in Figure 3.2. For combination therapy procedures, plug the single line electrode cable (ME 2261) into the electrode connection for Channel 1. 7. The Sonicator Plus 930 may be susceptible to interference originating from shortwave diathermy units operating in close proximity to it. Avoid operating the Sonicator Plus 930 adjacent to and simultaneously with operating shortwave devices. 8. Do not use sharp objects to operate the membrane panel switches. If the tough outer layer of the membrane is broken, moisture may leak into the switches resulting in switch failure. 9. Once you have verified proper functioning of your Sonicator 740, using the instructions in Section 4, please register the warranty for your Sonicator Plus 930 on line at http://www.mettlerelectronics.com/product-registration/.

NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Sonicator Plus 930 is used exceeds the applicable RF compliance level above, the Sonicator Plus 930 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Sonicator Plus 930.

4.1 A Note About Electrodes To ensure safe operation of the Sonicator Plus 930, follow the recommendations listed below: 1. We strongly encourage careful maintenance of the electrode system. This includes the lead wires as well as the pads themselves. Worn cables and/or poor pads (or the wrong sized pads) can have a significant impact upon treatment results. 2. Do not exceed the number of recommended uses listed on the instructions for V Trodes or other reusable self–adhesive electrodes. 3. Make sure that the entire surface of the electrode is contacting the patient. 4. Do not use moist hot packs to secure electrodes. 5. To avoid skin irritation due to high current density, do not use electrodes smaller in surface area than the 2" in diameter V Trode self-adhesive electrode (ME 2702). 6. Do not use conductive carbon electrodes with this product. 7. Whenever clinically possible, utilize the largest possible pads to reduce local increases in current density. In situations where small pads are required, use the lowest stimulation intensity necessary to achieve the desired clinical results. The table below illustrates the relationship between electrode diameter and current density. As you can see the current density increases rapidly when diameter decreases.
