The desiccant cartridge is located in the LADAR sensor. The cartridge contains the desiccant that dries the internal components of the LADAR sensor.

The moisture indicator is located on the cartridge. The indicator should be checked at the end of each shift. If the color is blue, the system is dry. If the color is gray, the system contains moisture. The cartridge must be changed.

The state of the desiccant should be checked regularly and the cartridge replaced if necessary.

Note: The cartridge should be changed once per year even though the indicator remains blue.
