CHAPTER 1 - INTRODUCTION

1.1. General

The Sonopuls 492 is equipped with two completely
identical multi functional electrotherapy channels and
a multifrequency ultrasound channel. The electro-
therapy channels can be used in combination or
totally independent. Combination of an electro-
therapy channel with ultrasound is also possible pro-
viding the possibility of combination therapy. The
remaining electrotherapy channel can meanwhile be
used independently. These combination opportuni-
ties along with the largest possible quantity of avail-
able current waveforms make this apparatus the ulti-
mate solution for your professional activities.
The apparatus is only meant to be used by compe-
tent personnel in physiotherapy, rehabilitation or
adjacent areas.

1.2. Therapy possibilities

Ultrasound treatments with 1 & 3 MHz continuous and
pulsed. Electrotherapy with low frequency, medium fre-
quency, TENS, High Voltage and Microcurrent currents.
Through the application of these currents it is amongst
others possible to diminish muscle tone, manage pain
and increase the circulation and regeneration of tis-
sue. Combination therapy of ultrasound and electro-
therapy is for instance ideal to localise trigger points
and or pain points.

1.3. Multi-frequency treatment head

The ultrasound treatment heads for the Sonopuls 492
are so-called multi-frequency heads. Each treatment
head can now supply both 1 and 3 MHz ultrasound.
The heads are available with a large and small treat-
ment surface and are also suitable for subaqual treat-
ments.
The excellent beam characteristics, ergonomic de-
sign and effective contact control of the multi-fre-
quency treatment heads make an optimal treatment
possible.

1.4. Finally

You have made a wise choice in selecting the
Sonopuls 492. We are confident that your unit will
continue to give satisfaction over many years of use.
Nevertheless, if you have any queries or suggestions,
please contact your authorised distributor.

Preliminary notes

It is important that you read these operating instruc-
tions carefully before using the Sonopuls 492. Please
make sure that these instructions are available to all
personnel who operates the equipment.
Pay attention to the following before using the
Sonopuls 492:
1. Keep yourself informed of the contra-indications
(see chapter 3).
2. Never leave the patient unattended during treatment.
3. The apparatus may not be used in close proximity
(i.e. less than 2 metres) to shortwave equipment.
4. The apparatus may not be used in so-called "wet
rooms" (hydrotherapy rooms).
The manufacturer cannot be held responsible for the
results of using this apparatus for any purposes other
than described in these operating instructions.
2.2. General
When the apparatus is switched on all vital functions
are checked by the internal microprocessor. During
operation of the apparatus the actual output of the
current is measured continuously and compared to
the requested output. Whenever a faulty situation is
detected the apparatus will switch off the current
immediately.

2.3. Contact control at incomplete contact

When the treatment head only contacts partially with
the body, the treatment is interrupted.
When not enough surface of the treatment head
makes contact with the patient the treatment is in-
terrupted (= contact control). The intensity display
starts flashing and the treatment time is interrupted.

2.4. Exclusions

Electrotherapy is not intended for the following spe-
cific applications:
• Intercranial treatment, like sleep therapy;
• Transcordial treatments (applying electrodes at the
thorax may increase the risk of heart fibrillation);
• Cervical occipital treatments.

2.5. Current density

The particular standard for Therapeutic Electrical
Stimulation Equipment is IEC 60601-2-10 (BS 5724
part 2.10). The maximum permissible Current Den-
sity is 2 mA R.M.S. per cm². To verify that this value
is not exceeded in electrotherapy, divide the current
output in mA by the effective electrode area in cm²;
a value of less than two should result.
