Section 1: Introduction
1.1 Introduction to the Sonicator 740
Thank you for purchasing the Sonicator 740 therapeutic ultrasound device from Mettler Electronics Corp.
The microprocessor controlled Sonicator 740 provides therapeutic ultrasound with enhanced reliability and
ease of use. An optional rechargeable battery is available to free you from depending on wall power. The
Sonicator 740 automatically self–tunes to the ultrasound applicator to ensure accurate delivery of
ultrasound.
The Sonicator 740 has a standard 5 cm² applicator at 1 and 3.2 MHz. An additional two applicators are
included with the 740x. 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 small treatment areas. All applicators attach to the Sonicator
740 using the same universal applicator cable.
The Sonicator 740 produces ultrasound in continuous and 10, 20 and 50% pulsed modes for maximum
treatment flexibility. The back-lit liquid crystal display (LCD) informs the practitioner about treatment
status. Time and ultrasound output intensity are actively displayed during a treatment. The “ultrasound
active” indicator on the display alerts the operator when ultrasound is being delivered by the applicator. An
additional LED on the applicator itself lights when ultrasound is being delivered and flashes when there is a
problem 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. Error conditions are
prominently shown on the display as well as all treatment parameters.
Figure 1.1—Sonicator 740 with all the available applicators
The Sonicator 740 has been certified by Intertek Testing Services to meet the requirements for ETL Listing
per the following standards:
UL 60601-1 Standard for Safety Medical Electrical Equipment, Part 1: General Requirements for
Safety Second Edition.
CAN/CSA C22.2 NO 601.1-M90 – Medical Electrical Equipment – Part 1: General Requirements for
Safety General Instruction No 1; Supplement 1; 1994 R(1997)
IEC60601-2-5 – Safety of Ultrasonic Therapy Equipment
In addition, the Sonicator 740 meets the following standards for radio frequency emissions:
FCC Part 18
IEC/EN 60601-1-2
Mettler Electronics Corp. has been certified by VTT Expert Services LTD to be compliant with EN ISO
13485:2003 and MDD 93/42/EEC Annex II requirements. In addition, Mettler is certified by DQS
Medizinprodukte GMBH to be compliant with ISO 13485:2003 (CMDCAS) Canadian Medical Device

Section 3—Installation
3.1 Installation Instructions
1. If you have chosen the optional battery pack, install the battery as seen in Figures 3.4 and 3.5.
2. To install the optional battery first remove the power cord. Then, remove the screws located on the back
panel of the Sonicator 740 on either side of the specification label using a Phillips screw driver, Figure
3.4.
3. Place the battery into the compartment as shown in Figure 3.5. Avoid depressing any of the buttons on
the keypad while inserting the battery. Turning the unit on its side while installing the battery will keep
the pressure off the buttons. If a button is depressed when the battery is being installed a continuous
beep will alert the user of this condition. To stop the alarm, remove the battery and reinstall it.
4. Close the battery compartment lid and reattach it by tightening the Phillips head screws.
5. Connect the line cord to the back of the Sonicator 740. (See Figure 3.1)
6. Plug the line cord into a grounded wall outlet that is rated at 100-240 VAC 50/60 Hz. Your mains power
supply must match the voltage requirements listed on the serial number label of your device. Do not
connect the Sonicator 740 to a power supply rated differently than that described above.
The unit comes equipped with a grounded line cord. This plug provides grounding for the Sonicator
740. Do not defeat its purpose by using adapters or any other means of attaching to a wall outlet.
7. If the optional battery is installed, it will begin charging as soon as the line cord is plugged into the wall
and the Sonicator is turned on using the switch on the back of the unit. The charging status will be
displayed on the display. Full charging takes up to four hours. The unit may be used while it is
charging.
8. Push the applicator cable connector into the round BNC receptacle located on the bottom of the
Sonicator 740 by lining up the slots with the pegs, pushing in all the way and rotating the ring ¼ turn
clockwise. Connect applicator to universal applicator cable using the same technique. To maintain
waterproof characteristics of the BNC connectors make sure that all connections are dry before
attempting to connect them, Figure 3.6.
9. Place the 5 or 10 cm² applicator into its receptacle. Line up the metal disc on the applicator with the
floating magnet on wall of the applicator receptacle and secure on the applicator hook, Figure 3.3. A
separate receptacle is located on the back of the unit for the 1 cm² applicator. Place it crystal-side-in, into
the holder. (Figure 3.1)
10. Warning: The Sonicator 740 may be susceptible to interference originating from shortwave diathermy
units operating in close proximity to it. Avoid operating the Sonicator 740 adjacent to and
simultaneously with operating shortwave devices.
11. Warning: If the integrity of the external protective conductor in the installation or its arrangement is in
doubt, the Sonicator 740 should be operated using the battery.
12. Do not use sharp objects to operate the silicone rubber keypad controls. If the tough outer layer of the
control is broken, moisture may leak into the unit resulting in switch and main board failure.
13. The optional battery pack may only be used in the Sonicator 740. Do not attempt to use other batteries
than Mettler part number ME7401. Additional precautions for handling the optional battery include:
• Do not store the Sonicator 740 for long periods with the battery installed.
• Keep the Sonicator 740 plugged into the mains to assure full battery charge when needed.
• Do not ship the Sonicator 740 with the battery installed.
• Avoid shorting the battery
• Do not immerse in water.
• Do not disassemble or deform the battery
• Do not expose the battery to fire.
• Do not dispose of the battery in fire.
• Avoid excessive physical shock or vibration.

Mettler Electronics Corp. — Rev.G_06/28/12

• Keep out of the reach of children.
• Never use a battery that appears to have suffered abuse.
• Lithium ion batteries are recyclable.
• Regulations for disposal vary for different countries. Dispose of in accordance with local
regulations.

Before you start:
a) Review precautions and contraindications in Section 5.
b) Verify connection of the line cord to a grounded wall receptacle and the Sonicator 740 or
that the battery is charged.

Up/Down arrows. Pressing the up or down arrow momentarily will
increase or decrease the ultrasound power in 0.1 W or W/cm² increments.
