Priority of DSC versus VHF
If a situation occur where a conflict between the VHF and the DSC functionality occurs (for
instance voice transmission on a working channel – using PTT, simultaneously with trans-
mission of a DSC call), the DSC transmission will be prioritized. As a consequence the
following VHF functions may need to be re-initiated if DSC activity has occurred while these
were active:
•
Replay
•
Scanning
•
Dual Watch
•
PTT
A normal received DSC call request will appear on the screen as soon it is recognized on
channel 70. This will not affect VHF radiotelephony before OK is pushed, unless automatic
channel shift has been configureded (See chapter: Automatic Channel Shift:)

Radio Configuration and Settings
This section describes the configuration and setting possible to control from the operator
front and that is not described elsewhere in this manual.
If your equipment need configuration beyond these possibilities, you must call you dealer for
special support.
4.8.1
Inactive Display
Whenever the radio is left in a state where the information/message display is not in use
(pure radio communication mode), the information display will return to inactivity or standby
mode. This will also be the case if the unit was left in a simple menu for 10 minutes.
The required and prefered default inactivity display is, that position and time stored for DSC
operation is shown along with the ships identity (MMSI). This mode will always appear after
start-up. The user might change the default display to be blanked (zero illumination to
minimize disturbance at night). To use this mode menu (4.6.3) Idle Display is selected. Press
on OK will toggle the Blank Display to be used.
If blank display is selected for inactivity display, and the radio goes into activity mode,
inactivity mode will just leave the screen blank. To quickly display the position and identity
information in this mode you can push the on/off button for a short time. This will show the
information screen for 15 seconds before it will turn off.
4.12.2
Notations for Date and Time
On the inactivity display and when the UTC radio time needs to be manually updated the
notation for time entry is:
•
yyyy/mm/dd hh:mm
In all logs (DSC logs and system logs)
•
dd/mm hh:mm (in overview list)
•
dd/mm-yy hh:mm:ss (in detail log descriptions)
