IMPORTANT:
1. The silica gel loses its effectiveness when the dry camera is
opened. To prevent the lens from fogging up, replace the silica gel
bag every time when you open the camera and conceal the gel bag
in the camera within two minutes of exposing to the open air.
2. For each newly replaced silica gel bag, allow it to absorb moisture
for at least 5 hours before operating the camera.
