When using an inductive coil applicator with a fixed connection cable, feed the cable through the
aperture first before attaching the applicator. Remove the applicator by pushing back the slide
(18)
and pulling the applicator out of the hoIder. The central joint of the arm (23) is factory-adjusted to a
basic braking force. After long-term application, it may be necessary to readjust the basic braking
force due to wearing of plastic parts and brake disks. To adjust this joint, remove the blue cover using
a screwdriver and tighten the hexagonal bolt located below the cover by about a half turn.
Adjust the breaking of the horizontal motion of the arm at the joint (25) by tightening the lower slotted
nut.
3.4 Applicators and applicator cables
Inductive coil as well as condenser applicators may be used with the Auto*Therm 395 (see Section 10,
Accessories).
3.4.1 Condenser applicators (spaced applicators)
Three pairs of different diameters are available. The optimum ratio of the fixed electrode-to-skin
distance (measured from the outside of the applicator casing to the inner electrode plate) and the
corresponding electrode area is characteristic for applicators used with the Auto*Therm 395. This
results in low-loss transmission of the high frequency energy from the generator via applicator to the
patient (for further information see 5.4, 5.5 and 5.6).
3.4.2 Flexible condenser applicators
These applicators are available in two different-sized pairs. The permanently attached, highly flexible
cable ensures maximum flexibility at the point of applicator connection and high adaptability to bent or
curved parts of the patient‘s body. The optimum distance between the applicator and the skin is
achieved by using thick felt spacers that have to be placed in a cloth bag together with the applicator.
One to three of the 5 mm thick felt spacers are used for tuning between electrode and skin. The
number of spacers depends on the application and characteristics of the tissue. Velcro fasteners or
rubber bands may be used for fastening these applicators.
3.4.3 Inductive coil applicators
Three different sizes of the inductive coil applicators are available to adjust to the size and volume of
different treatment areas (for further information see 5.4 and 5.5).
This inductive coil applicator uses the high frequency magnetic field generated by the inductive coil of
an electrical resonant circuit for therapy. All inductive coil applicators of the Auto*Therm 395 are
electrically shielded and connected to the unit via removable, shielded cables.
This means, electric interference of nearby devices (neuromuscular stimulators, etc.) is avoided as
much as possible. Additionally, the removable shielded cables are fitted with a special EMC filter to
suppress harmonic interferences.
3.4.4 Applicator connection cables for condenser applicators
Highly flexible, low-loss special cables (29) are used to connect the condenser applicators to the unit.
A hooked connector is provided to prevent damage or kinking of the cable in the applicator connection
area. Electrically superior, flame-resistant silicone insulating materials have been used to avoid cable
defects and help prevent probems when used incorrectly (e.g. in case the cables touch each other).
Patients should not touch the cables during treatment to avoid undesired heat application. Therefore,
any extra cable should be fed through the lower arm
(24) to secure it. If necessary, insulate the
patient from the cables by placing several layers of towelling between the patient and the cables.
