Operation Manual

14 Issue 1 M-2 AIS Operation
Password access control
The M-2 AIS unit has three levels of access control - each of which is protected
by its own password. The three levels are:
User level protects voyage-related data such as that displayed on the
Voyag e m ode : Own voy ag e page.
Operator level protects operational data such as the channel regions shown
on the Setup m ode : Channe l re g ions page.
Service level this level of access is available only to authorised service
agents and protects ship's static data (such as the MMSI and
IMO numbers) which must be programmed into the unit.
The user and operator passwords are optional. If either of them is not required
(permitting any user to change the voyage or operating data) then they may be
set to the special password "NONE" (which is the default setting). It is
recommended that the operator password is set, and that the user password is
not used.
If a user password is configured, but the operator password is left as "NONE"
then the user password will not be effective since the system will grant operator-
level access without requiring a password.
Each page protected by a password has an Edit softkey - for instance the Own
Voyag e page displays the Edit VOYAGE DATA softkey whilst the Channe l
Re g ions page displays the Edit CHANNEL REGIONS softkey. When the Edit
softkey is activated, the user is prompted to enter the corresponding password.
Press the 'Enter' button to bring up the on-screen keyboard, and then enter
the appropriate password into the top field. Then activate the Verify
PASSWORD softkey in order to check the password. If the password is correct,
you will be granted access to the preceding page.
When the password is set to "NONE" then the user is permitted to edit the
corresponding page immediately without being prompted to enter the password.
