4.3.1 Sound Indicator
▪ Periodic beeping signal is emitted when RF energy is delivered.
▪ Warning sound tone indicates Bad Coupling.
▪ When the measured temperature approaches the Cut-off temperature, the tone
beeps double in speed. It becomes faster when the Cut-off temperature is reached.
4.3.2 External Cut-Off Temperature Control
The selected Cut-Off temperature in the range of 35-42
o
C is constantly maintained and
when reached, RF delivery is adjusted automatically to maintain required temperature.
Temperature is monitored by temperature sensors in the Handpiece (in the external
electrodes).
4.3.3 Internal Cut-Off Temperature Control
The selected Cut-Off temperature in the range of 50-70
o
C is constantly maintained and
when reached, RF delivery is adjusted automatically to maintain required temperature.
Temperature is monitored by temperature sensors in the Handpiece (in the internal
electrodes).
4.3.4 Treatment Time Control
The treatment time is selected in the range of 15-120sec and indicates time that Cut-Off
temperature is maintained.
4.4 Handpieces
Handpiece comprises internal active electrode, external return electrode, both with
temperature sensor, handle, cable and connector.
There are three types of handpieces, both with external and internal electrodes.
4. Handpiece HP101306A has an external electrode diameter of 13.5mm and internal
electrode of 1.2mm diameter and 10cm long. Maximal RF power 20W
5. Handpiece HP172206A has an external electrode diameter of 13.5mm and internal
electrode of 2.2mm diameter and 17cm long. Maximal RF power 20W
6. Handpiece HP172246A has an external electrode diameter of 22mm and internal
electrode of 2.2mm diameter and 17cm long. Maximal RF power 40W
