Appendix B – Maintenance
This Appendix describes the periodic maintenance items you need to
perform on your camera to keep it in optimal condition.
Cleaning the Window and Filters
1) Get a can of compressed air from a photo store, as well as a small
camera hair brush
2) Thoroughly clean and dry the brush using isopropyl alcohol
3) Remove the front cover of the camera. If you want to clean the
Window remove the Filter Wheel. While the camera is open be very
careful to avoid activities that could spark the inside of the camera with
static, just sit in your chair. If you have to get up and get something,
discharge your body to a metal surface (not the camera) after sitting
back down.
4) Tilt the camera up to face horizontally and blow out the entire chamber
with the compressed air. Finish with a blast right on the Window from
a half inch away. Be VERY careful not to tip the can of compressed air
past 45 degrees as often an oily liquid will come out that is hard to
clean off.
5) If you have a dust particle that will not blow off, poke it loose with the
brush. They cling to the surface due to static, so you may end up just
pushing them out of the way. The static forces are quite strong!
6) The outside of the window is easily cleaned with a cotton swab or Q-tip
and a little isopropyl alcohol. Use one end of the Q-tip to swab it with
alcohol and the other to dry it. Never re-use a Q-tip and do not scrub –
use gentle pressure
7) Replace the front lid.
8) If you have a few small dust specs, don't worry. it is almost impossible
to get them all and a flat field will take care of them well.
9) Filters are cleaned the same way.
Replacing the Desiccant
The ST-8300 contains a small packet of
desiccant
that keeps the CCD from
frosting when it’s cooled. This desiccant should last for several years but it
won’t last forever. If you start seeing things appear in your images that
look like shadowed tendrils you should suspect frost on the CCD and it may
be time to replace the desiccant. You can get the replacement
desiccant from us and it’s easy to replace with the following
procedure:
2. Remove the camera’s front cover by loosening the four
socket-head cap screws (SHCS) that hold it in place.
