the device prior to attempting to adjust the treatment intensity so that the Auto*Therm can properly
tune to the patient’s body.
The intensity control knob (17) can be turned continuously. It has no stops to prevent clockwise or
counterclockwise rotation. Turning to the right increases the intensity in the steps shown below. These
steps apply to both the continuous and pulsed modes of operation.
Up to 30 W In 3-W steps
From 30 W to 90 W In 5-W steps
From 90 W to 200 W In 10-W steps
The Auto*Therm 395 automatically tunes to the patient when the intensity control knob (17) is turned
clockwise. The tuning symbol “A” appears in the time display (14) instead of time while the device is
tuning to the patient. No changes to any settings can be made while the device is tuning. Press the
“RESET” key (2) or turn the intensity knob (17) counterclockwise to make changes to the setup
parameters during this time. The coupling process is indicated in the coupling LED light bar (16) . The
energy transfer to the patient is achieved when all the LEDs are lit (16) . You can change the position
of the treatment applicator(s) during the tuning process while the device is tuning to optimize energy
transfer. You can move the applicators when the intensity is low (3 W – 9 W).
When tuning is completed, the treatment time is again shown in the time display (14) and, the actual
output power (intensity) is shown in the intensity display (15) . The tuning process can be repeated by
turning intensity knob (17) counterclockwise until the intensity display reads “0“ and then turn the
intensity control knob clockwise to start the tuning process over. Once the device is tuned to the
patient, you can increase the intensity to the desired level by turning intensity control knob
(17)
clockwise until the desired intensity level is shown in the intensity display (15) .
The Auto*Therm 395 continuously monitors the intensity level. If the patient moves, the intensity is
automatically readjusted. When patient coupling to the applicators is not sufficient, the coupling
indicator
(16) is only partially lit or off. If there is insufficient coupling, the intensity cannot be adjusted
to the maximum level. The desired intensity (set point) is never exceeded even when coupling
improves. Thus, the patient is protected from any unintended higher power levels as long as the
power adjustment is not changed.
5.8 Emergency shut off
The output of the Auto*Therm 395 can be turned off as follows:
a) Turn off power switch (1) . (Entire device).
b) Press “RESET” key (2) . (The unit is returned to the stand-by mode.)
c) Simultaneously, press the time keys (12) and (13) . (The mode of operation and applicator type
remain stored.)
d) Turn intensity knob (17) counterclockwise until “0” appears in the intensity display (15) . (The
mode of operation, applicator type and remaining treatment time are kept stored.)
e) End of the adjusted treatment time. (The mode of operation and applicator type remain stored.
Stop the beeper by turning the intensity knob counterclockwise.)
f) The patient can turn the unit off by pulling the ripcord (34) . If the patient pulls the ripcord
the unit produces a series of beeps and the code “FEC” appears in the intensity display (15) .
Press the “RESET” key (2) in order to return to the standby mode.
