Notes:
•
The default source of speed is the speed log, and it is the one selected after every start-up;
after a switch from standby to TX-On the last selection is reloaded.
•
An SDME speed over the ground based on acoustic sensors has limited depth range and
may in specific cases be affected by poor acoustic conditions due to e.g. air or ice below the
sensor.
•
The speed through water measured close to the hull is affected by the tide and by the cur-
rent, so from time to time it will differ significantly from speed over the ground. An SDME
measuring speed through water may in specific cases be affected by poor conditions due to
e.g. air or ice below the sensor. If the sensor measures only the longitudinal component of the
speed, the transversal ship component is unknown to the radar.
Course
It indicates the ship’s course according to the speed source selected. Obviously, in case of
single axis speed log, the course field shows the gyro value.
Own ship geographic position
It indicates the ship’s Latitude and Longitude, data incoming from an EPFS (i.e. GPS).
Invalid data is displayed in red, low integrity data in black on a yellow background.
When the EPFS is not available or in timeout, the geographic position value is replaced with a
red --.—
UTC or local time
The date and time indicated can be switched between UTC and local time, manually en-
tered or received from the EPFS; this selection can be performed using the shortcut sugges-
tion from the Help line, when placing the trackball cursor on the label, which says “UTC” or
“Local Time”. Pressing the left SK when the correspondent suggestion says “Time Setup”, the
“Date and Time Settings Menu” will be displayed and the operator will have the possibility to
change the following:
•
Choose to display UTC or local time; the local time zone offset is normally sent by the ZDA
sentence.
•
Set a manual local zone if for any reason the local time zone offset is not available (it can be
applied to the Manual Time also).
The changes are applied immediately, but to store them in the memory and reload them after
a restart, the “Accept” button must be pressed.

Note:
The manual date and time are not stored in the memory even if pressing the “Accept”
button, due to the fact that the system is not able to run the clock while it is turned off.
