My ST-5C/ST-237 is frosting. What can I do?

1. Remove the front cover and then remove the CCD Chamber cover.

2. Take out the small white package of desiccant and gently cut the end off the packet, being careful to not let the desiccant beads inside spill out.

3. Bake the desiccant beads (don't bake the white packet or else it will melt) at 400 F for 4 hours.

4. Pour the beads back into the packet and seal it with a small piece of scotch tape.  Use a small piece of tape so you don't block the pores in the white tyvex package.

5. Replace the desiccant packet in the head and put the head back together.

6. Let the camera head sit for 4 hours before cooling again to let the desiccant equilibrate.
