CHAPTER 1
GENERAL INFORMATION
1.1 Introduction
The Phyaction 190 is an appliance for ultrasound therapy and it can be used for combination therapy with an
external electrotherapy appliance.
In this chapter the important features from the users manual for service personnel are listed. In the next chapter
the theory of operation will be explained. In chapter 3 is described how service personnel can check the
operation of the Phyaction 190 and what maintenance operations should be carried out. The next chapter
contains information which could be very useful for trouble shooting such as a description of the automatic self
test and a list of the error numbers. The operations that have to be carried out if you want to exchange a printed
circuit board or another module are described in chapter 5.
1.2 Safety aspects
1.2.1 Electrical safety
The equipment can only be used in areas with provisions in accordance with current statutory requirements.
Pay particular attention to the use of protective earth, otherwise the patient leakage current can rise above the
permitted limit for type BF equipment.
1.2.2 Explosion safety
The equipment is not suitable for use in areas where flammable gasses or vapours are present. Therefore,
remove the mains plug from the socket before the area in which the equipment is located is disinfected, since
some disinfection solutions evaporate and subsequently form an explosive mixture.
1.2.3 Operational safety
- Using the equipment in the vicinity of short wave or microwave equipment can influence the correct
operation of the unit. Using this equipment when high frequency surgical equipment is connected to the
patient at the same time can result in burning under the electrodes when using it for combination therapy.
- Patients who have electrical implants (i.e. pacemaker) may only be treated following medical advice.
- The equipment is not suitable for use in damp areas.
- The equipment may not be disinfected or sterilized.
- Whenever the equipment is switched on (using the main switch) the microprocessor checks the entire
system for correct operation.
- The ultrasound heads, including the cable and the connectors should be checked regularly. In particular
attention should be paid to damage to the ultrasound heads through which liquids can enter the ultrasound
heads.
- The ultrasound heads should be handled carefully, because the properties of the ultrasound heads can alter
due to rough handling.
1.2.4 Use of the appliance
The equipment and accessories should only be used by authorized personnel and in accordance with all
instructions included in these operating instructions.
The Phyaction 190 is only to be used for providing ultrasound therapy. When connected to an electrotherapy
appliance the Phyaction 190 can be used to provide combination therapy.
1.2.5 Radio interference suppression and electromagnetic compatibility
This equipment meets the guidelines for ISM equipment relating to electromagnetic compatibility and is radio
interference suppressed according to EN55011. Also see section 1.2.3
