3.8. Protecting Messages for Permanent Storage
3.8.1. Introduction
Initially, all stored NAVTEX messages will be automatically erased one by one from
memory on a first–in–first–out basis as the equipment continues receiving new
messages after the message storage capacity limit (200 messages) is reached. If you
wish to protect a specific message for permanent retention in memory, proceed via the
steps given below. Up to 50 messages can be protected, and are saved in a separate
area of the non–volatile memory, allowing an additional 50 new messages to be stored.
