Kestrel Instruments Support & FAQs

Why is my screen dark or pixelated on start-up?

This condition can happen when the memory becomes full in the Kestrel.  Clearing the memory log should fix this condition.  Please try doing the following:

  • Take the batteries out of the Kestrel.
  • Hold down the power button for 30 seconds
  • Put the batteries back into the Kestrel.
  • Turn on the Kestrel.  Wait several minutes (could take a little while so be patient) until the pixilation clears and you can press buttons.
  • Go to Main Menu->Memory Options and clear the data log.
  • After data log is cleared, turn Kestrel off and then back on.  It should startup quicker now.
