Miscellaneous functions and settings
Additional functions are available within a second menu level. These can be accessed by
simultaneously pressing and holding 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 transducer [probe check]
This function is used for quick veri
fi
cation of whether the ultrasonic transducer is recognised
by and can be correctly activated by the HF generator. After a change in probe or in operating
conditions it is possible, for example, that the HF generator cannot synchronise with the ultrasonic
transducer and issues an error message, e.g. Error 011. The HF frequency is reset to the base
value and the function is restored if no device fault or other cause is present.
The set value is "off". In order to activate the function, set the parameter to "start" using the arrow
keys
, and then press the "START/STOP" key. See chapter 6.2.1 for 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 HF or ultrasound frequency for the
ultrasonic transducer. Depending upon the probe used and the operating conditions, the frequency
can
fl
uctuate signi
fi
cantly in some instances. When switched off, the HF generator saves the
current frequency value and uses it as the start value when switched on again. If there are
signi
fi
cant deviations in the current HF frequency, this can lead to malfunctions.
Important:
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 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
. Smaller values result
in a darker image and larger values result in a lighter image. The default value is 22.
