801 Stuck in “CALIBRATION”?

Is your 801 powering up and getting stuck with “Calibrating” on the display (picture 1)? When unit is powered up the 801 Seed counter will perform self tests however the “calibrating” should only appear for 3 seconds. If it stays on longer than that it is a problem that is usually due to a lack of light getting to the solar cell. The problem will cause the seed counter to not count accurately.

The 801 has a light source on the right side (RED LED or WHITE LAMP). On the left side is a solar Cell. There are two glass lens that the light passes through before getting to the solar cell.

There are a few simple things to try:

  1. Clean BOTH Glass LENS one on each side of the chute. To get the glass LENS out push the lens from behind towards you by using a small flat screwdriver see picture 2 and 3.


  2. Pull the lens out with your fingers and clean using glass cleaner or ISOPROPYNOL Alcohol.
  3. Slide LENS back in by holding outside of lens do not touch glass surface.
  4. Now using a Q-Tip clean the inside of the chute where the LIGHT passes through. See picture 4.
