To view the current firmware version, complete the following steps:

  2. Switch to the tool kit page by touching the tool symbol on the buttom row.
  3. Touch "Settings".
  4. Touch "System".
  5. Touch "About"
  6. The system will display the firmware version at the top ("Software Version"), the unit ID on the second line, followed by various copyright information.
