Replacing the Desiccant
Your camera includes a high-performance molecular sieve desiccant tablet which is used to
avoid condensation inside the CMOS chamber. Although this desiccant will last a long time
it may eventually need replacing 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: the 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.
We recommend leaving the camera in a warm, dry environment with the port open while you are
recharging the tablets to ensure any remaining moisture can dry out.
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.
