3.2.4 Miscellaneous functions and settings
Additional functions are available within a second menu level. These can be accessed by
simultaneously pressing the "SET" key and arrow key . Switching between these functions is
accomplished with the "SET" key in the manner already described. The menu level can only be
exited by pressing the "START/STOP" key. In doing so, settings and function statuses are carried
over and executed.

Check the ultrasonic converter [probe check]
This function is used for quick verifi cation of whether the ultrasonic converter is recognised and
can be correctly activated by the ultrasound generator. After a change in probe or in operating
conditions it is possible, for example, that the ultrasound generator cannot synchronise with
the ultrasonic converter and issues an error message, e.g. Error 011. The frequency is reset
to the base value and the function is restored if no device fault or other cause is present.
The default value is "off ". In order to activate the function, set the parameter to "start" using
the arrow keys
additional information.
Search for resonance frequency [scan frequency]
This function is an expansion of the above-mentioned "probe check" function. In addition,
a frequency scan is conducted in order to determine the correct ultrasonic frequency for
the ultrasonic converter. Depending upon the probe used and the operating conditions,
the frequency can fl uctuate signifi cantly at times. When switched off , the ultrasound generator
saves the current frequency value and uses it as the start value when switched on again.
If there are signifi cant deviations in the current frequency, this can lead to malfunctions.
Note:
After a successful scan while in continuous operation (pulsation = off , time > 30 s), start with
an amplitude setting of 50 % and check the operation. Next, set the desired default value.
Setting the monitor contrast [contrast]
With this function, the monitor contrast can be adapted to the local light conditions. The contrast
values range between 1 and 68, and can be set with the arrow keys
in a darker image and larger values result in a lighter image. The default value is 22.
