Login and Logout
Each time the DTE and Communication Unit are turned on, the vessel should be
registered with the Inmarsat C system to enable communications between vessel and
CES. This is called login.
If the vessel is not going to be using the equipment for a prolonged period it should
logout from the Inmarsat C system so the vessel can be registered as inactive.
