Important Notice to users of Nikon Microscopes Digital camera Control Unit DS-L2

Details of those problems

Problem 1:

When you capture images on the DS-L2 during February 1st thru 29th of a leap year (*1) (*2), image files are dated wrong as follows. Image file captured on February 1st: It is not dated, or dated totally different.
Image file captured on February 2nd-29th: The date attached with the file is one day before.
When folders are created on the DS-L2 during February 1st thru 29th of a leap year, the same problem will occur.
The problem is limited to the date and not with image files themselves.

• (Note *1) : The upcoming leap year is year 2008.
• (Note *2) : If the date and time setting of the DS-L2 you have is not correct,
  the same problem will occur during February 1st thru 29th that you set in the unit.

Problem 2:

Calibration in the tool menu can't recognize a correct relay lens magnification as follows.
* When you use the calibration function by inputting object/relay lens magnification data, the calibration does not recognize the correct magnification from the relay lens and the scale data given by calibration turns out to be wrong.
* When our Nikon Microscope Eclipse 80i/90i (*3), Eclipse LV series and Multizoom AZ100M are connected to the DS-L2, the DS-L2's calibration automatically recognizes object lens magnification and you should be able to get the scale data only by inputting the relay lens magnification.
However, for the same reason, the scale data after the calibration turns out to be wrong in this case too.
* The problem does not happen when you use manual calibration mode.

• (Note *3) : When you connect your camera to the back side of the 90i DIGITAL IMAGING HEAD "DIH-E/M",
  the problem doesn't happen since the magnification of relay lens is unchangeable.
