well.
· You cannot acquire the image of the dark specimen under the reflected fluorescence observation or the darkfield
observation (DP28-CU: Specimen that needs the exposure of 1/2 seconds or more at ISO100 equivalent. DP23-CU:
Specimen that needs the exposure of 1/2 seconds or more at ISO200 equivalent). When acquiring the image of the
particularly dark specimen, the lack of pixels caused by the cosmic ray or the constant bright points may be noticed,
but they are not phenomena caused by the failure of the instrument.
· Specimens with intensity distribution that is not suitable for the metering require the use of spot metering or the
exposure compensation.
· When the electronic zoom is used for enlarging the image during focusing, the roughness of the image may be
noticeable depending on specimens.
· When attaching or detaching USB equipments or when accessing USB equipments, the frame rate may be
decreased or the image may be blurred temporarily.
· The maximum frame rate according to the resolution of the live image is shown in the table below. The maximum
frame rate is given when the exposure time is set lower than values shown in the table below.

· If the scale bar imprinting function or the measuring function is selected, the time to acquire the image is longer than
normal.
· When observing a specimen that contains few white area, the traceability of auto white balance is deteriorated.
· "Format of recording media" usable with DP2-AOU is NTFS, FAT or FAT32. When using the USB recording media in
unsupported format, it is necessary to format it in NTFS, FAT or FAT32 on your PC.
· When using the USB recording media for acquiring movies, it is necessary to format it in NTFS.
· Depending on the recording media's speed to write images, etc., the frame rate when acquiring the movie may be
reduced or frames may be skipped. If frames are skipped, the movie is played as if fast-forwarded. Frames may also
be skipped when the available space of the recording media is small. Therefore, when acquiring the movie, it is
recommended to save the movie on the hard disk (E: Images) in DP2-AOU.
