2. It is strictly forbidden to disassemble any hardware and software of this system, and the Company shall
not be held responsible for the consequences caused by the repairs or re-installation of the equipment
by the non-designated personnel of the Company.
3. Under unnecessary conditions, we do not recommend use of UPS power supply; if you need to configure
the UPS power supply, please buy the products of qualified manufacturers or contact the Company;
when it is not used, switch off the host of B-ultrasound instrument and the UPS, and the Company is
not responsible for any damage to this system due to UPS power supply failure (short circuit, fire, etc.).
4. Other equipment connected to the system (such as regulated power supply) must comply with the
relevant electrical safety requirements, and the Company is not responsible for damage to the system
and customer loss caused by failure of other equipment.
5. The battery can be charged and discharged cyclically 300-500 times, and when the usable time of
battery is found to be shortened significantly, please replace the new battery in time to avoid failure.
6. Charging time of the system: about 5 hours, discharging time: about 3.5 hours. The battery can be used
for about 3.5 hours when it is normal in the early stage, with the increase of charging and discharging
times in the later stage, the battery capacity will gradually decrease, and the battery service time will
also decrease.
7. Please be sure to turn off the power when the equipment is not in use, and unplug the power cord and
the power terminal board if necessary. The equipment (power connection panel) should be kept away
from the roof with water leakage, including other water sources. Such conditions may cause short

1.5 Basic principle
Veterinary ultrasound scannerworks in this following procedure: different tissues of animal body possess different
densities and speeds of transmission of ultrasound, i.e. different acoustic impedance (product of media density and
sound speed).when piezo-chip (transductor) gets certainly regulated electric impulse, it will produce ultrasound
with certain frequency. when this ultrasound (sound energy) is injected into animal body, different organ surfaces
will produce reflection echo, the different size reflection is received by the transductor which emitted ultrasound
and is changed into electric impulse, when this electric impulse is amplified, demodulated, digital scanned, shifted
and some other handling, video standard signal is produced and organ cross-sectional images are displayed on the
monitor.
