  • Page 9: Precautions For Use

    1 PRIOR TO USE Precautions for use Make sure that this Instrument must be installed in a place without any intensive electromagnetic wave or the wave generating devices. An intensive electromagnetic field causes noises to interrupt the Instrument from func- tioning proper diagnosis and measurement.
  • Page 10 In case of a malfunction, do not attempt to repair the instrument yourself. Place a sign on the instrument indicating that it is malfunctioning and contact your Tomey representative. Do not technically modify this instrument. Please be informed that the instrument should be inspected regularly.
  • Page 11: Unpacking And Receiving Inspection

    When unpacking the instrument, make sure that all of the compo- nents are present and that none of them are visibly damaged. If any items are missing or damaged, contact your Tomey represen- tative. Be sure to keep the box and the packing material for use if the instrument is moved to another location.

  • Page 13: Outline Of Operation

    Outline of operation The AL-100 is an ultrasound instrument designed for measuring the axial length of the eye for medical ophthalmic use. Acoustic output is switched off after measurement. Ultrasound energy is emitted from the probe tip. The probe acts as both the transmitter and receiver of ultrasound en- ergy.

    3 OPERATION PROCEDURES Safety precautions ALWAYS cleans the probe tip before taking a measurement on a human eye. NEVER use the probe if there is any visible damage to its tip. Such use may cause an incorrect maeasurement and/or damage to the cornea. This instrument is designed exclusively for ophthalmic use.
  • Page 20: Preparation Before Use

    Connecting the power cord Power cord should be plugged into the terminal with a proper direction. Plug the power cord connector (1) into the terminal (2) on the back of the AL-100. All of 3-Pin in the plug must be connected.
