Chapter 3 Preparing an Exam
You should complete the preparations before the exam, such as move, position and adjust the system,
connect the power supply, probe or other peripherals.
3.1 Positioning the system
Keep the distance of 20cm from the left side and rear of the system to the walls during
use. Otherwise, the temperature inside the system will increase and cause system malfunction.
Place the system on a level desk carefully.
3.2 Booting the system
Two methods can be used to supply power for the system: mains supply and battery.
When the adapter is connected to the mains supply, the battery is charged until full.
The battery life will be affected if the battery is used frequently. Please use the adapter as often as possible.
Connecting to the mains supply:
System Specifications: 100V-240V~50Hz/60Hz, 120VA-140VA
The AC power plug for the ultrasound system is a three-pin grounded plug and should never
beconnected to any two-pin outlet or an adapter. Otherwise, there is danger of electric shock.
Ensure the potential-equalization lead wire is connected before inserting the equipment power plug. Otherwise,
there is danger of electric shock.
Steps for connecting the mains supply are as follows:
Connect two ends of the power cable to the hospital-graded mains supply and the power input port at the
rear panel of the system respectively, and ensure the connections are secure.
3.3 Using the Battery
3.3.1 Precautions
Do not assemble or disassemble the battery, because there is danger of explosion.
Charge the battery through the diagnostic ultrasound system only. Otherwise, there is danger of
explosion.
Replace the battery provided by the manufacturer only
，
and Can only be replaced by technical personnel
Do not short-circuit the battery by directly connecting the system with metal objects.
