Operating Manual

89-042 Issue 5 5
3 Operation
Please read all the warning notices at the front of this manual before turning on the
Transponder.
3.1 Activation
It is recommended that UAIS should not be switched off and should remain in
operation continuously. However, based on the Master’s professional judgement,
either transmission may be inhibited or the UAIS may be switched off entirely if
continuous operation might compromise the ship’s safety or security. Reactivation
must take place as soon as the source of danger has disappeared. This might be
necessary in waters where pirates or armed robbers are known to operate. It might
also be necessary to switch off UAIS during some cargo handling operations.
Actions of this nature should always be recorded in the ship’s logbook.
3.2 Menu Navigation
The “keyboard” is the touch-sensitive screen of the VDU. The keys displayed
change according to the other information on the screen. Touch a key square to use
that key function.
All on-screen menus follow the same basic principles to navigate around them.
Using the up and down arrows allows the operator to move quickly
and easily through the current menu system.
Once the required item is highlighted PRESS either: -
to enter a sub-menu.
or to change the data in the selected field.
or to confirm the change.
or to stop the action and return to the previous command.
or to go to the previous menu.
Some menu options are automatically selected depending upon the input data
available.
The data entry keyboard is divided into three screens as shown overleaf.
