  • Page 5: To Ensure Safety

    CONTENTS TO ENSURE SAFETY This Service Manual has been compiled for the purpose of facilitating repair and maintenance of the WR1000 Series Thermal Arraycorders by Graphtec service personnel and other persons who have undergone equiva- lent technical training. Maintenance or repair by unauthorized service personnel is to be strictly avoided. Because the WR1000 contains numerous internal components with a high electric potential, such work by unauthorized service personnel could cause human injury or serious damage to the recorder.

  • Page 8: Upgrading The Firmware

    2. UPGRADING THE FIRMWARE The version of your WR1000’s firmware can be upgraded by rewriting the flash ROM on the pertinent circuit boards using one of two methods. You can upgrade the firmware by loading the update program from either floppy disks or from a personal computer via the RS-232C interface.
  • Page 9 When the message appears to indicate that the upgrade program has been ENTER normally terminated, turn off the WR1000 and remove the second disk. Note that the upgrade file for the sub CPU and the print pattern file are contained in the second floppy disk.
