4.18 Alarm Signals Menu
(Default = On)
In this menu, the status of different alarm signals can be viewed and enabled or
disabled. The alarm signals will give validity information to the operator in case a
fault occurs. Therefore it is recommended to keep all the alarm signals set to ‘On’
which is the default setting.
The transponder contains a Built-In-Integrity-Test (BIIT) that continuously monitors
the standard functions of the equipment. This relay facility should be connected to
the ship’s main alarm panel. If any failure or malfunction is detected that will
significantly reduce the integrity or stop operation of the UAIS, a single alarm
message is displayed on the VDU touch-screen and the BIIT alarm relay activated.
If the alarm status continues the appropriate alarm message is repeated every 30
seconds on both the MAIN and AUX ports for display on other connected
equipment.

4.21 DGNSS Set-up Menu
UAIS can transfer differential data corrections via the AIS channels (message 17).
Data received via the RTCM input port may be sent to 2 reference stations whose
geographical co-ordinates are known and which have been manually set up. If the
reference station is transmitting RTCM message 3, it is showing its own coordinates that UAIS can store. No more than 4 reference stations can be stored at
any one time.
4.22 Engineering Mode
Engineering mode option in the Main setup menu is designed for testing and
setting up an UAIS at the factory, it is protected by a password known only by
authorised personnel. Users must not activate Engineering mode.
