With Manual Expose activated, you can adjust the exposure time directly by

changing the number of seconds in the Exposure Time ﬁeld. Type in a number

or use the arrow buttons next to the ﬁeld.

In UV or White image mode, when the speciﬁed exposure time is reached, the

last captured image will be displayed in the Chemi Doc image window. The

camera will continue to integrate the image on the CCD, updating the display

whenever the speciﬁed number of seconds is reached.

Once you are satisﬁed with the quality of the displayed image, click on the

Freeze button to stop the exposure process. The last full exposure will be

displayed in the image window.
