Section 19. Maintenance

FIGURE 19-4. Front Main Body O-ring
It is recommended that the O-rings be inspected whenever opened or at a
minimum of every two years (with desiccant replacement) to ensure that the
seal integrity is maintained. Contact Campbell Scientific for details on
replacement parts.
It is important to note that the button cap O-ring and the front main body O-
ring are both glued into place to prevent the O-rings from inadvertently falling
out. Do not attempt to remove these O-rings unless they are being replaced.
19.4 CC5MPX Desiccant
The CC5MPX contains three small desiccant packs inside of the camera. If the
camera is frequently opened (i.e. backplate or lens tube removed), then the
desiccant packs of the camera should be replaced yearly. Otherwise the
desiccant packs should be replaced every 2 years as preventative maintenance.
The desiccant that is supplied with the camera is an indicating type of
desiccant. There is a small viewing window on the pack that shows the color
of the desiccant. If the desiccant is blue, then it is still good. If the desiccant is
pink, then it is saturated with moisture.
The desiccant packs are located under the PCB on the bottom of the camera
(see FIGURE 19-5). Needle nose pliers will be useful in helping to remove
and reinsert the three desiccant packs.
