3.8 Replacing the desiccant

Your camera includes a high-performance molecular sieve
desiccant tablet which is used to avoid condensation in the
CCD
chamber. Although this desiccant will last a long time it
may eventually need replacement or recharging, in which case
please follow the instructions below:
- To replace the desiccant, open the desiccant port with the supplied plastic tool
and a screwdriver and take out the used tablet.
- To recharge the desiccant, place the tablet in an electric oven at 200ºC for 2 hours.
Take the tablet out the oven (CAUTION: tablet will be very hot) and allow it to cool
down.
- Place the recharged tablet back in the camera, replace the port cover and tighten
(no need to over-tighten). Wait 24 hours before connecting the camera again.
You will notice that there is a filter inside the desiccant chamber. The purpose of this is to
avoid contamination of the chamber when the desiccant is being replaced. The filter is
very fragile and should not be touched.
