Certify biopsy Needle before using it. Do not use curved needle.

The following is a public statement by the one of United Stated Ultrasound Association, AIUM,
on the safety of ultrasound diagnosis.

Ultrasound has been in use since the 1950’s. AIUM declares the clinical safety of ultrasound
scanning and acknowledges its effectiveness as the type medical equipment and its possible
use for diagnosis of pregnant women.
There has been no case which shows cause of any physical damage to either patient or user
during properly performed diagnosis with an ultrasound scanner. Although it might be possible
that unknown effects of ultrasound may come to light in the future, so far the benefits far
outweigh any unproved danger. Theoretically, there are two possible ways that ultrasound
could have negative affect on the human body.
One is the heat generated by ultrasound as it passes through the human body. Doppler
produces the most heat, and it followed by color and B-mode imaging. However, even in the
case of Do ppler the amount of heat is so minor that there is no equipment that can measure it.
The other one is the possible formation of a cavity by the ultrasound. However, there has been
no clear evidence that this can actually occur in the human body.
In conclusion, no negative biological effects of ultrasound have been proven thus far.

Mysono 201 Section 1-4. Installation

In case of the system on, it takes about 5 hours to charge.
In case of the system off, it takes about 3 hours to charge.
If need a more information of the time for charge or discharge, refer to [Appendix C.

System specification] in the user manual.

Check the battery state by LED color on the system during charging.

- Without Battery: No Color

- Under charging: Orange

- Complete charging: Yellow

- Take off the adaptor: Red

Discharge the battery
When the battery is discharged (the system is working without AC adaptor), the system power
will be compulsorily turned off after a period of time (90 minutes) for safety and efficiency of
battery and user will hear the warning “beep” sound every 10 seconds.

4.4 Power ON / OFF

Hold the pressing the power switch located at the left side of the system for minimum 1sec.
whenever turns on/off the system. It is to prevent the system down and battery discharge.

l How to turn on the system

1) Hold the pressing the power switch for minimum 1sec. with connecting the AC adaptor

or inserting the charged battery.

2) Check the image display on the monitor.

l How to turn off the system

1) Hold the pressing the power switch for minimum 1sec.

2) Check the image disappears on the monitor and switch off.

4.5 Using AC adaptor

It takes about 5 hours to charge completely under connection of AC adaptor to the system.
Refer to [Appendix 0b. connecting the peripheral device] in user manual.

2. Front -End Board (F/E)

2.1 General Description
F/E board receives the echo signal of ultrasound and the signal clamps the high voltage to +/-

0.6 V by Limiter then pass through TGC Amp. And then it reordering and its signal path is
reduced in half by OP Amp Adder that add the Symmetrical signal per scanline.
Then, to reduce the Aliasing, pass through the Low pass Filter and travels it to Beamforming IC
after converting it to A/D. Beamforming IC control the signals of 8 channel by Rx focusing, and
forward them to Mid Processor IC MGA015A on DSC.
Its main components are ;

- MOSFET Driver EL7222 x 16 ea

- PMOS TP2520 x 16 ea

- NMOS TN2524 x 16 ea

- Dual TGC Amp AD604 x 8 ea

- Cross Point Switch (16 x 8) MT8816 x 1 ea

- OP Amp AD812 x 8 ea

- Beamforming IC MCB014A x 2 ea

- XC95144 for Control x 1 ea
