Portable Digital Color Doppler Ultrasound System
Turn on the system without connecting the AC adapter to use the battery as the source.
Disconnect the output plug of the AC adapter from the system while it is on, and the system
uses battery as the source automatically.
You may charge the battery while the system is off by connecting the AC adapter to the
system.
You may also charge the battery without turning off the system.
Instructions for charging battery with system on:
1. Connect the equipotential point at the rear panel to safety ground (earth).
2. Attach the connector of the power cable to the AC adapter firmly.
3.
Connect the power plug of the AC adapter to the outlet marked with “hospital grade”.
4.
Connect the DC output plug into the power supply socket on the ultrasound system.
The system automatically charges the battery and takes the AC supply as source.
Caution!
• Make sure to follow the above steps. Connecting the DC output plug
of the AC adapter, which has no AC input, into the system can trigger
protection mechanism which automatically shuts down the system.
• If auto-shutdown due to misoperation occurs, connect to the AC
source and restart the system.
• Charge the battery only when the ambient temperature is between
0°C and 45°C.
• When you hear the beep sound and the LED BAT is blinking, it means
that the battery power is almost depleted. You should save your data
and turn off the system or connect the system to an AC power source
immediately.
Note:
Once the system is turned on, the control panel will be illuminated. It
takes about 1 minute for the system to enter the preparation mode (EXAM
screen).
Caution!
DO NOT plug in any external USB drive before the system startup com-
pletes, otherwise the µSCAN function might be interrupted.
