  • Portable non-invasive middle ear analysis testing instrument
  • Thermal Printer
  • Older discontinued model
  • ON/OFF SWITCH DOES NOT WORK - IS ON ALL OF THE TIME

    The unit appears complete however, it has not been fully tested since we are not experts with it. When it is turned on the print head moves the paper feeds a bit. The power and IPSI lights turn on the main unit. The bottom yellow light on the proble lights solid, and if the end of the probe is touched the middle green light blinks then goes off and the bottom yellow light turns solid again.
