Note: Fields of ITEM 4 shall be filled as it is automatically cleared when the screen is called if
not an error box will be displayed when Updating is selected
Note: Registration marking (aviation) is right justified. When less than 7 characters are used
the software automatically performs the right justification and fill to the left with
“Space” characters as required by Cospas-Sarsat specification
Note: Specific ELT Number is a figure between 1 and 4. It encodes spare bit 82 & 83 as follow
1 00, 2  01, 3  10 & 4  11
Note: In order to keep the follow-up with previous encoded ELT in service, « Simplified Beacon
Id » is displayed with the two solutions, without Specific ELT Number (/EXAMPLE/ as
displayed in previous releases) and with Specific ELT Number (new capability,
/EXAMPLE_2). It gives the same C/S 15 hex when Specific ELT Number is set to “1”
(one) as in that case spare bit 82 & 83 are coded 00.
