EMS COMBINATION 850 Manual page 27

Apply sufficient coupling medium to the area to be treated. EMS Therasonic
coupling medium is recommended. Apply the active face of the transducer to
the treatment site via the coupling medium, and press the ultrasound intensity
up key. The treatment indicators on the control panel and on the transducer will
light, the timer will start to count down and the output display will show 0.1
2
W/cm . If the treatment time is zero or a suitable transducer is not connected to
the ultrasound output socket then the Combination 850 will give a short beep.
Move the transducer over the treatment site in small circular paths whilst
increasing the output to the desired intensity using the ultrasound intensity up
key. Each press will increase the intensity by 0.1 W/cm
between the transducer and the treatment area for more than two seconds, then
the timer will cease to count down, the light on the transducer and the
treatment indicator on the control panel will turn off and the intensity on the
LCD will flash indicating poor contact. The power applied to the transducer
will also be reduced to a low level. When good contact is restored, the light on
the transducer and the treatment indicator on the control panel will light, and
output display will cease to flash and the timer will continue to count down.
If the output intensity is returned to zero, using the ultrasound intensity down
key, before the treatment time has elapsed, the timer will display the remaining
treatment time. When the output is turned on again the treatment will continue.
At the end of the treatment the timer will display 00:00, the ultrasonic power
from the transducer will be terminated, the light on the transducer and the
treatment indicator light on the control panel will turn off, the LCD will show
zero intensity and power and a long (approximately 2 seconds) alarm will
sound. The display will return to the ultrasound set-up screen.
Remove the transducer from the treatment area, wipe any coupling medium
from the transducer face and return it to the holder at the rear of the handle.
Remove the remaining coupling medium from the treatment site.
COMBINATION 850
Always keep the face of the
transducer in contact with
the treatment area, and
always keep the transducer
moving to avoid any
standing waves.
If the transducer face is
lifted off the treatment area
or if for any other reason
there is insufficient contact
