If the transducer face is lifted from the treatment site or if for any reason there
is insufficient contact between the transducer and the treatment site for more
than two seconds, the power applied to the transducer will be reduced to a
low level. The treatment light on the transducer will start flashing, the
treatment time will cease to count down and the status bar will display
‘CONTACT’, indicating that the required output cannot be delivered.
An audible alarm will sound if this option has been selected in ‘System
settings > Contact alarm’. When good contact is restored, the treatment
indicator on the transducer will relight, the status bar will display
‘TREATMENT’ and the timer will continue to count down.
If the output intensity is returned to zero using the rotary control, before the
treatment time has elapsed, the display will show the treatment time
remaining. When the intensity is increased again the treatment will continue.
When the treatment time reaches 00:00, treatment is terminated. The
intensity and power displays will go to zero, ultrasonic power from the
transducer will be turned off, the treatment indicator will turn off and the unit
will give a two second beep. Remove the transducer from the treatment site,
wipe off any coupling medium and return the transducer to its cradle on the
front of the unit.
Remove the remaining coupling medium from the treatment site.
The transducers are also suitable for treatment using a water bath. This is
especially useful when treating areas which are not uniform such as feet or
hands. When using a water bath it is advisable to use degassed water (water
that has been boiled to remove any air and then allowed to cool). After the
part of the body has been immersed in the water, remove any air bubbles
that may have accumulated on the skin. Set up the treatment parameters
and then immerse the transducer in the water before turning the output on.
Hold the transducer with its face approximately 1 cm away from the treatment
site and using the rotary control set the required intensity remembering to
keep the transducer moving in small circular paths to prevent standing
waves. At the end of the treatment the intensity and power displays will read
zero, and the ultrasound power will turn off. Remove the transducer from the
water and dry both it and the area treated.
