(10) Soft-touch keyboard, plastic exterior case, which are good-looking,portable, and convenient to operate.

Operationand Precautions of Ultrasound Scanner (Ultrasonic Diagnostic):
Keyboard Preparation
Unlock the keyboard by pressing the lever on the front panel.
Power Cord
Adhere to the electrical power rating. The system is adaptable to 220/230 volts(To use 100/120 volts is optional to users. Contact with the manufacture if100/120 volts is needed). Plug the system power plug into the AC outlet, whichis located in the rear panel. To connect the system to the power supply: ensurethat the wall outlet is of the appropriate type. Make sure that the powerswitch is turned off.

Unwrap thepower cord. Ensure sufficient slack in the cable so that the plug is not pulledout of the wall if the system is moved slightly. Push the power plug securelyinto the wall.

Warning
To avoid risk of fire, the system power must be supplied from a separateproperly rated outlet. The system is supplied with a power cord. Under nocircumstances should this cord be altered or changed. To assure groundingreliability, connect to a grounded power outlet. (USA AC outlet is 100/120Volts, Europe outlet is 220/230 Volts)

Connectingthe Probe
Insert the probe plug in the socket exactly. Revolve the locking handle by 90degree to fasten it. To uninstall the probe, revolve the locking handle inreverse direction by 90 degree and unplug it. Caution: It is strictly forbiddento pull out or insert the plug when the machine is power on. To disconnect theprobe, hold the plug instead of pulling the cord to avoid damage of theultrasound scanner (ultrasonic diagnostic).

GroundingProtection
If no grounding socket is available, or grounding conductor is not connected,you should use a metal wire, whose cut-area is <1mm2, to connect thegrounding conductor to the ground. Caution: the setting up of grounding protectionshould be under the instruction of the experienced electrician or relevantstandard.

Switchingon
First, turn on the magnetic lock on the front panel of ultrasound scanner(ultrasonic diagnostic), then press down the Power button, which will light thepower-indicate LED on the keyboard. When apparatus runs into normal workingstate, you can use brightness, contrast, gain and near-restrain buttons to getrequired image.

Diagnosis
The patient should lie on his (her) back on the bed,and apply the contact agent (medical ultrasonic coupling) on the to-be-checkedpart of the patient. At this point, the section picture of the part isdisplayed on the screen with the probe contacted the to-be-checked partclosely. With the altering the directions and gradient, various sectionpictures can be observed. Choose the section picture you need and pressFreeze to get the picture as basis of diagnosis. During the period, if thebrightness, contrast and gain of the picture remains unsatisfying, you canadjust the BRIGHT and CONT, or the signal gainNEAR, FAR and GAIN until theclear picture is displayed.

Measurement
Through diagnosis, freeze the optimal picture and measure the specificallyconcerned position. The measurement contains: distance, perimeter, area, M-typeregular examination, and gestational examination

Photoand Print Photo
When the picture is frozen, use the instance camera orregular camera to take a photo of the picture.
Connect the Video-Picture printers AV-input cable plug to the output socket ofthe apparatus. Turn on the printer, and follow the instruction of it tooperate.

Turnoff the Ultrasound Scanner (Ultrasonic Diagnostic)
When operation is finished, turn off the power of ultrasound scanner; if itwill not be used for a long time, disconnect the power plug from the socket.
Caution: Do not un-plug the power cable when the ultrasound scanner is stillworking. Wait for 2-3 minutes to re-start the apparatus after shutting it downin order to protect the apparatus from being damaged.

Maintenanceof Ultrasound Scanner (Ultrasonic Diagnostic):
Regular maintenance
Check the power supply on a scheduled basis. If the power supply is out of thenormal range--AC220V10%, 50Hz1Hz, you should not turn on the apparatus at anytime. Check the power supply cable and probe cable regularly, and replace itwhen any damage or rupture occurs.

(1) The environment should be confirmed to the standardsmentioned.
(2) The ultrasound scanner shall be kept clean. After the plug is pulled out,it shall be wiped with soft cotton ball containing alcohol. When the interiorpart needs to be cleaned, use the fan to tidy the dust.
(3) Do not turn on or turn off the ultrasound scanner frequently, Wait for 1-2minutes to re-start up the apparatus after shut down in order to protect theapparatus from being damaged.
(4) The ultrasound scanner shall be put steadily. Carry and place it lightly.
(5) Avoid placing heavy things on the apparatus.
(6) If the ultrasound scanner is idle for a relatively long time, put it in thepackage box and keep it properly. The environment should confirm to therequirement of 9.
(7) If ultrasonic diagnostic is idle for a long time (over 6 months), it shallbe powered on twice a week for at least 2-4 hour every time.

Maintenanceof the Probe:
The Probe is a vulnerable component. During the application, avoid impacting,falling or squeezing. During the pause of diagnoses, the probe should be putinto the probe box, and you should also press the Freeze key to keep theapparatus in a freeze state.
Contact agent which is applied on the probe shall be medical ultrasoniccoupling. Strictly avoid any other type of corrosive coupling applying to theprobe.
After clinical use, and contacting with the patient, the probe shall besterilized and cleaned with medical alcohol. It must be put into the probe box.
It is not allowed to soak the probe in other conducting or corrosive liquid,otherwise the probe and its sheath will be corroded.
When the probe is soaked into liquid, the distance above the sound window shouldbe more than 10mm; otherwise, the interior components would be damaged by theliquid which seeps into the probe. Check the exterior of probe regularly toensure that the outer layer of the probe is fully closed. If the connectionbetween the probe and the ultrasound scanner (ultrasonic diagnostic) isproperly set up, you should not disconnect them randomly to avoid theconnection problem of probe plug and socket.
NOTE: Petroleum or other organic solvent is forbidden to clean, sterilize, anddisinfect the probe; otherwise, the probe will be destroyed.

Caution: When the ultrasound scanner (ultrasonicdiagnostic) is working, unplugging the probe is forbidden. Even slightimpacting or falling down of the probe might damage the chip inside the probe,and this damage is irreparable. If the front film is broken, do not dissembleit at will, and do not use it any more since there is high-voltage electricityin the probe. Send it back to the manufacturer, and we will repair it for yourfurther use.
