Anaheim, CA 92805.
1.2 The Sonicator 730
The Sonicator 730 is a microprocessor-controlled device providing continuous or
pulsed ultrasound. It delivers 1 or 3 MHz ultrasound through four interchangeable
applicators. They can be attached to the generator without recalibrating because the
Sonicator 730 is self-tuning.
Two applicators are shipped with each generator. Applicators are sealed to facilitate
underwater treatments, and are repaired by returning them to a Mettler Electronics
Corp. authorized service facility.
The membrane control panel has clearly labeled key pads that produce audible
feedback when activated. LED timer and output displays are large and bright.
Verify conformance to specifications at least yearly.
1.3 Precautions
1. The Sonicator 730 operates with high voltages. Servicing should be performed by
qualified ultrasound 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
because of the extensive use of surface mount circuitry. Any attempt at replacing
a surface mount component will result in damage to the board. Replace entire
circuit board assemblies only!
3. For maximum safety, plug the Sonicator 730 into a grounded wall outlet of proper
voltage only. Follow general safety practices for medical electronic equipment.
4. The Sonicator 730 requires 115 VAC {230 VAC in some models] (110%), 50/60 Hz
primary power. DISCONNECT THE LINE SUPPLY CORD PRIOR TO DISASSEMBLY
OF THE UNIT. Line supply voltage is present on primary components exposed by
removing the back cover.
5. Use calibrated test equipment in good working order.
6. USE OF CONTROLS OR ADJUSTMENTS, OR PERFORMANCE OF PROCEDURES
OTHER THAN THOSE SPECIFIED IN THIS MANUAL AND IN THE Sonicator 730
INSTRUCTION MANUAL, MAY RESULT IN HAZARDOUS EXPOSURE TO
ULTRASONIC ENERGY.

Sonicator 730 Maintenance Manual
7. Do not operate the Sonicator 730 in close proximity to operating shortwave or
microwave diathermies.
8. Replace line fuses with specified type and rating only, to avoid risk of fire or other
damage.
9.. Do not operate the membrane control panel with pointed objects such as pencils,
pens, or tools.
10. Make sure ail connectors are tight with all pins making good contact when
reassembling the unit after service.
11. As a prescription device, the Sonicator 730 may be sold only to, or on the order of,
a physician, physical therapist, or other practitioner licensed by the state in which
he/she practices.
1.4 Labels
Each medical device must be uniguely identified for traceability and device history.
This is accomplished with serial numbered labels unigue to each device.
Product labels provide performance data, and must remain on the device at all times.
Preserve label integrity during repair and servicing when actions such as removing
access covers could cause label damage.
Please include model and serial numbers when requesting service assistance from the
factory.

Mettler Electronics Corp.
Section 2—Equipment Description
2.1 Equipment Layout
The Sonicator 730 has two printed circuit boards (or three boards on units produced
prior to January 7, 2003, S/N 122U6375 and earlier), up to four ultrasonic applicators
(two standard), a membrane control panel, a main power switch, front and back
housings, and interconnecting cables. A block diagram is shown in Fig. 2.1(or Fig. 2
Old Block Diagram).
Power Supply Board
The Power Supply Board has a power transformer on it that mounts the board to the
front housing with four screws. The input to the Power Supply Board is filtered mains
power. The outputs are regulated +5, and +12 volts, and a 0 to 40 volt variable supply.
The DC output voltages are available at a header at the bottom of the board assembly.
The Power Supply Cable connects from here to the Main Board.
Main Board
The Main Board contains the Microcontroller and the Eprom that holds the program.
Also on the board is a display decoder, four 7-segment LED’s for treatment time
indication, three 7-segment LED’s for output power indication, , and six individual
(green} LED’s for control status information. The LED’s fit through holes in the front
housing, and shine through the membrane switch. The Main Board also contains the
1 and 3 MHz VCO, the 1 and 3 MHz RF output stage, and the 1 and 3 MHz matching
network. On older units, the main board had only 1 MHz functions and the ultrasound
RF energy was coupled out through a BNC connector to a short cable that connects to
the 3 MHz Module. The front panel membrane switch is connected to this board by
means of a zero insertion force connector.
3 MHz Module, older units
The 3 MHz Module is located on the back of the Power Suppiy Board. The module
plugs into the Power Supply Board directly, and is held in place by two nuts. It
contains the 3 MHz VCO, the 3 MHz RF output stage, and the 3 MHz matching
network. It also contains a relay to switch the output between the 1 and 3 MHz
outputs. The module is controlled by signals from the Main Bd. On newer units these
functions have been incorporated into the main board.
Applicators
Four applicators connect to the Sonicator 730. These include: one 10 cm? applicator
at 1 MHz (7310); two 5 cm? applicators, one at 1 MHz (7305) and one at 3.3 MHz
(7335); and one 1 cm? applicator at 3.3 MHz (7331). All Mettler Electronics Corp.
ultrasound applicators are labeled for the model Sonicator with which they may be
used. Other applicators from other Sonicator 730’s may be interchanged and will
function properly because of the self tuning feature of the Sonicator 730 circuitry.
Applicators connect to the Sonicator 730 with a universal applicator cable (ME7391)
which has water resistant BNC connectors at each end.
Other Components
The power input connector, main power rocker switch, and the applicator BNC
connector are mounted to a bracket at the bottom end of the enclosure.
The Main Board is connected to the Power Supply Board with two flat cable
assemblies. These are made with insulation displacement connectors. Care should be
taken when removing them to pull on the connectors, not the flat cable.

Sonicator 730 Maintenance Manual
The membrane switch is secured to the front housing with pressure sensitive
adhesive. If the membrane switch is ever removed it must be replaced with a new one.
The membrane switch connects to the Main Board with a zero insertion force
connector. To remove the membrane switch tail from the connector pull the connector
body up until it stops and then gently pull the tail from the connector. If the tail does
not come out easily the connector body is not up far enough. Never pull the tail out
without the connector body being fully up, it will damage the contacts on the tail. To
reinstall the membrane switch tail make sure the connector body is all the way up.
Insert the tail into the slot until it bottoms out, then push the connector body down
until it seats.
All components in the primary circuit are UL approved and must be replaced with
identical parts.
The firmware on the Main Board requires the same controls in manufacturing,
processing, and changing as any other component.

2.2 Theory of Operation
Power Supply Bd Circuitry
Mains power goes through the RFI filter in the power cord connector, through the
power switch and to the Power Supply Bd. On the board it runs through primary
fuses, and into the power transformer. The secondary of the transformer is also fused.
The secondary of the transformer produces 28 VAC, center tapped. Half the winding is
rectified, filtered, and fed to two three terminal regulators to produce +5 and +12
volts. The whole winding is rectified and goes to a switching regulator which produces
the 0 to +40 volts required for the variable ultrasound output.
The connection from this board is the power connection to Main Board. The signal
connection from Main Board (to 3 MHz Module) and 1 MHz power connection to the 3
MHz Module apply to old units only.
Main Board
The reset IC monitors the +5 supply, and telis the microcontroller to start as soon as
power is good. The micro sends signals to initialize the system. The micro then scans
the membrane switches for operator input, and sends appropriate signals to the
display driver IC which controls the displays.
When the unit is in Hold the micro is always looking at the applicator ID ports to see
if an applicator is connected. If no applicator is connected it displays “Errl” in the
timer display. When an applicator is connected, and time is on the timer display, and
the Go button is pressed, the micro turns on the ultrasound output. (The relay on the
3 MHz Module Board is switched to the proper position for the applicator connected
older units only.) The micro then monitors the current return from the applicator, and
uses
that information to set the correct VCO frequency, and to control the voltage to
the output stage to produce the desired output power.
The connections from this board are: power connection from Power Supply Board,
connection to the membrane switch, signal connection to the Power Supply Board (to -
3 MHz Module), and 1 MHz output to the 3 MHz Module.
8 MHz Power Bd, New units incorporate these functions on the Main board.
The 3 MHz Power Bd contains the 3 MHz VCO circuitry, the 3 MHz power output
stage, and the 3 MHz output network. When a 1 MHz applicator is connected to the
unit the relay on this board connects the 1 MHz output from the Main Board to the
output connection on this board. When a 3 MHz applicator is connected the relay
connects the 3 MHz network on this board to the output connection. The 3 MHz VCO
and the frequency select relay are controlled by signals from the Main Bd. This board
sends
applicator ID and current return signals back to the Main Bd.
The connections to this board are: power and signal connections from Power Supply
Board and Main Bd, 1 MHz power input from the Main Bd, and the 1 or 3 MHz output
connection to the external applicator connection.
Applicators
Each applicator consists of a handle with a transducer ring assembly at one end and
a BNC connector at the other. The transducer ring assembly consists of a threaded
stainless steel ring that has a piezo ceramic disc epoxied to it. The ring may be
removed from the applicator for replacement at a Mettler Electronics Service Center.
Inside the handle is an ID resistor that is used by the micro to determine which
applicator is connected.
Applicators are designed to be repairable. The ultrasound crystal ring assembly
should only be replaced at an authorized Mettler Electronics Corp. service facility.
10

Sonicator 730 Maintenance Manual
The universal applicator cable interconnects the applicator to the generator. It is
detachable at both ends with BNC connectors. These connectors are specially
designed to be water resistant. The type, length, and shielding of the cable are critical
to the proper operation of the unit. Only applicator cables supplied by Mettler
Electronics Corp. should be used.

mm from the ceramic disc surface when the
radiation is emitted into the equivalent of an infinite
medium of distilled, degassed water at 30° C, and
with line voltage variations in the range of +10% of
the rated value.
The beam of the applicator is circular in all planes
parallel to the applicator face. A few inches from the
face, it is a single smooth beil-shaped curve. Nearer
the face the pattern varies more due to phase
cancellations. Sample curves measured in the far
field from the surface are shown in Figures 2.3, 2.4,
