Are Autocom units waterproof?

Autocom units are water-resistant by design, but they are not waterproof. Why? All electronics create heat, which is why your computer has a cooling fan and your television case is so well vented.

These allow hot air to exit the unit before condensation forms, which is why it is important that the unit be able to breath and is, therefore, not watertight.

Autocom has taken additional steps to protect each unit including coating the circuit boards, utilising tough injection-molded cases that unlike metal casings will not allow moisture to condense, and engineering with tight tolerances to make sure that stop gap assembly techinques (e.g. sealing openings with epoxy/mastic or potting (filling the entire space with mastic)) are not required.
