INTENDED USE

The LG “Pro Series Elite” is a portable ultrasound device that generates deep ultrasonic waves within body tissues for the treatment of selected medical conditions such as pain relief, muscle spasms, and joint contractures, but not recommended for the treatment of malignancies. This is an FDA-regulated product available by prescription only. Keep out of reach of children.

EXPLANATION OF ULTRASONIC STIMULATOR EFFECT

The LG “Pro Series Elite” is an ultrasonic therapeutic device that generates pulsed high-frequency sound waves (1MHz) that are transferred to a specific body area via a sound head probe. The pulsed sound waves travel deep into the tissue to generate vasodilation, which helps increase blood flow to the treated area.
Therapeutic ultrasound is found to help relieve pain and reduce muscle spasms and is one of the most frequently used therapies by physicians and physical therapists. Most patients will feel nothing at all during treatment, while some patients may feel slight warmth.

**CONTRAINDICATIONS

**

Do not use over or near bone growth centers until bone growth is complete.
Do not use over a healing fracture.
Do not use over the eyes.
Do not use on patients with implanted neurostimulation systems because tissue damage can occur at the location of the implanted electrodes resulting in severe injury or death. This can also damage the system components.
Do not use to treat malignancies, nor in the region where malignant tumors are present.
Do not use on patients with demand-type cardiac pacemakers.
Do not use on someone who is pregnant.
Do not use over ischemic tissues in patients with a vascular disease where the blood supply would be unable to follow the increase in metabolic demand and may result in tissue necrosis (tissue death).
Do not use over the carotid sinus nerves or arteries, laryngeal or pharyngeal muscles.

PRECAUTIONS

Do not use on patients with hemorrhagic diatheses (excessive bleeding disorders).
Do not use over an area of the spinal cord following a laminectomy, i.e., when major covering tissues have been removed.

Please read this instruction manual carefully before using the US Pro 2000 ™ 2 nd Edition Portable Ultrasound Unit.

Turning on the device and head warming feature:
Turn the device on by sliding the power switch upwards (towards “ON”). The power indicator light will illuminate. The device will automatically enter the preheat mode.
The six indicator lights will flash alternately during this period.
When the preset temperature is reached or the maximum preheat time has ended (3 minutes), all of the indicator lights will ﬂash ﬁve times. Once complete, the device enters standby mode. This head warming feature takes approximately three minutes from a cold/room temperature from start to finish.
If the warming feature is not needed, press both the “MODE” button and the “TIME” button simultaneously. The device will go back to standby mode.
When the device is in standby mode, the modulation duty cycle defaults at 5% and the (L) indicator light will be illuminated.
WARNING: During the head warming period, the following items should be noted:
The device will automatically exit the head warming feature if any load is detected in the preheating process. Therefore, do not apply the ultrasound head to the patient during the warming period.
To restart the warming feature, you will have to power off the device and turn it back on again.
Apply transmission gel:
Wash the area to be treated so that it is free of oil and dirt. Apply a generous layer of ultrasound transmission gel on the treatment area. The gel acts as a coupling
substance and ensures effectiveness. The area treated should be two times the diameter of the sound head.
Set ultrasound intensity:
Press the “MODE” button to select the modulation duty cycle. The mode button has three levels, Low (L) – 5%, Medium (M) – 50% and High (H) – 100%, each level corresponds to a LED light indicator.
Set treatment time:
Press the “TIME” button to cycle through the treatment time (5, 10 and 15 minutes), as shown by the “TIME” indicators. When the time is chosen, the system will start working. During working time, the user can press the “TIME” button to adjust the treatment time.
Place sound head-on the treatment area and begin treatment:
Move the sound head in a slow, flat, circular motion over the skin surface of the treatment area. Apply the sound head evenly (in time) over the treatment area (see page 11 for Load Detection System Caution).
Turn off the device:
After completing the treatment session, the device will automatically shut off and all indicator lights will be off. Power off the device physically by sliding the power switch downwards (towards “OFF”). Unplug the unit from its power source.
Clean the device after every use:
With device turned off, clean the ultrasound head/probe with a wet towel or soft tissue. Do not immerse the device in water. Always store the device in its protective case at room temperature in a dry location.

LOAD DETECTION SYSTEM CAUTION:

The device has a load detection system for safety. When the treatment head does not have good contact with the skin, the device will stop treatment automatically, and the time indicator light will ﬂash one time. The device will not continue the treatment program until good contact is made.
The device has a temperature protection function. When the temperature of the treating head exceeds 107°F (42°C), the treatment will automatically stop and the time indicator light will ﬂash two times. The device will not continue the treatment program until the temperature is below 104°F (40°C).
