The VHF is capable of supporting transmission of All Ships DSC urgency messages with

These settings can be changed only from the service interface. Reception of these calls is
always possible.
If the VHF is configured for using these calls it will work in the following way:
After powering up (normally) the VHF it will not be possible to use these call types
(message: “Call type not enabled in VHF” if selected.)
Each of the call types can be enabled via the menu 4.5.3. (the filled square indicates
the call type that is enabled).
After enabling the call property can be added in an All Ships Urgency call sequence.
4.6.2 Automatic acknowledgement
The VHF can be set to automatic acknowledgement of the following calls:
Safety position requests - Default disabled after power-up
Safety test requests - Default enabled after power-up
Routine polling requests - Default enabled after power-up
After power-up the behavior can be changed from menu 4.5.4.
The automatic acknowledgement (if enabled) will take place without informing the operator.
The calls are stored in the receive/transmit log. The operator might experience a short
interruption in functionality while the automatic acknowledgement takes place (e.g. scanning,
dual watch).
