M-2 AIS Operation Issue 1 39
Channel Regions
Used to set geographic areas which have specific AIS channels requirements.
When entering a new channel region, the new values may be entered on any
one of the channel region pages (including region 0 - the "High Seas" region).
Once the new information has been saved and confirmed (by using both the
"Save CHANNEL REGION" and "Confirm CHANNEL REGION" softkeys) then
the new region will be allocated to a particular page according to the following
rules:
If the geographic co-ordinates match or overlap with an existing region
then the old region will be replaced by the new one.
Otherwise, the new region is stored in page 1 and the other pages
are moved downwards. If all the pages are used, the oldest region is
deleted.
