1.3.5 Fitting the head holder As standard, a head holder is supplied with each treatment head. Before you use the Phyaction 190 for the first time, we advise you to fix the head holder(s) to the appliance. The ultrasound treatment head can be connected to the appliance easily and in a user-friendly manner into the head holder. - Page 5 The display indicates which format of treatment head has been selected at that moment. As soon as the Phyaction 190 is switched on using the mains switch or from the stand-by position, or as soon as a treatment 1. GENERAL INFORMATION...

As soon as you hear the buzzer you should release the keys. If you did it right, you will see at the bottom of the start-up screen that the Phyaction 190 is in service mode. You can now enter the service menu by holding down the yellow key for about 3 seconds. - Page 13 (see section 1.3.6 Checking the ultrasound heads or Appendix 2 TUNING THE ULTRASOUND TREATMENT HEADS). If all of these things are checked and meet the specifications, then the treatment head is probably defective and should be exchanged. 3.

Introduction If a Phyaction 190 is defective, in most cases the unit will detect an error in the automatic self test. A full description of this test will therefore help the service technician in finding the error. In the next paragraph you will find this description. - Page 15 The serial (RS-232) interface is initialized and tested. ERROR 27 is generated if a time out occurs. Timer 2 is initialized and tested. ERROR 09 with Value 02 is generated on a time out. 5. TROUBLE SHOOTING Service information Phyaction 190 / 190i - Page 13...
