CUT1 button has to be pressed and held
Press "PROG" button shortly and let off CUT 1
button
-The CUT display shows now "
ErA
". By pressing one program button (1-10) the relevant
program will be erased; the LED switched off
-By pressing the "PROG" button the user can return into the normal mode.
ATTENTION:
Adjustments that relay to the switch-off of single function units (i.e. footswitch
allocation or conscious switch-off by pressing an active step button twice) will be taken
from the standard mode into the program mode. If i.e. a monopolar footswitch handpiece
and a bipolar instrument are connected one of them is automatically blocked. The blocked
function will be shown by a black display of the relevant key field. By pressing one button
in this "dark" field it will be activated, the footswitch will be assigned to it and the former
active field will be shut dark.
If the user now switches from standard mode into program mode (by pressing PROG) and
chooses a program this activation/de-activation of the function field will remain unchanged.
This is independent from the conditions during storage and is also relevant if function
fields were turned off by a button.
5.1.1 Description of the Safety Equipment
This RF surgery equipment is provided with different safety devices in order to protect the user
and the patient from possible harm. In the following, safety and warning devices are described
which are indicated on the safety field [10] of this equipment.
1. Patient electrode (PE)
If a patient electrode with double contact area is used, the electrical connection between
equipment and patient electrode is automatically monitored as well as the application of
the patient electrode at the patient.
A good connection of the patient electrode is indicated by the illumination of a green LED.
A yellow LED indicates deterioration of transfer resistance between patient tissue and
patient electrode. The equipment can be activated further; however, the proper fit of the
patient electrode should be checked.
If the patient electrode is not connected or has a bad connection to the patient the red LED
blinks. Additionally a warning signal sounds twice if the connection is broken or if an
attempt has been made to activate the equipment. The equipment switches off and cannot
be reactivated. Only after correction of the patient electrode is reactivation possible. If a
single surface patient electrode is used this is indicated by the illumination of the green
and yellow LED’s.
2. Functional error
This warning device signals that the pre-selected parameters are not met by the equipment
(i.e. a significant exceeding of the selected output power).
When this condition reaches critical values which may endanger the patient additionally
an alarm signal sounds and the equipment switches off.
After switching on during a self-test the micro controller senses an error a warning tone
sounds, the equipment function is disabled and an error code is displayed.
3. Dosage error
If due to overload the equipment respectively the selection of a too low power step in
relation to the surface size of the electrode, an insufficient output voltage is reached, this
red display lights up. To switch LED off either increase the power or decrease the surface
size of the electrode.
All units have short time storage of the adjusted values during power failures. If the power fails for
less than 8 seconds the unit will store the last adjusted working parameters. When the main
power is back on the unit will deliver these values after a short self check.
