15. DSC SETUP
15.1 INDIVIDUAL DIRECTORY
The HX890 has a DSC directory where the names of vessels or persons, and the
associated MMSI that you wish to contact via Individual Calls, Position Requests
and Position Report transmissions, may be stored in memory.
To transmit an Individual Call, this directory must be programed with information
of the vessel you wish to contact, similar to a cellular phone’s telephone directory.
Refer to section “ 10.4.1 Setting up the Individual Call Directory ” for details.
15.2 INDIVIDUAL REPLY
The radio can be setup to automatically (default setting) or manually respond
to a DSC Individual call that requests you to switch to a working channel for
voice communications. When “ MANUAL ” is selected the MMSI of the calling
vessel is shown on the display allowing you to see who is calling and decide if
you want to switch to the working channel and reply. This function is similar to
caller id on a cellular phone.
Refer to section “ 10.4.2 Setting up the Individual Call Reply ” for details.
15.3 INDIVIDUAL ACKNOWLEDGMENT
The radio DSC operation can be setup to automatically (default) transmit a
reply, or set so the radio will not automatically reply to an individual call.
Refer to section “ 10.4.3 Enabling the Individual Call Acknowledgment ” for details.
15.4 INDIVIDUAL RINGER
A telephone like ring may be set to alert you that the radio has received a DSC
individual call. The default setting is 2 minutes, however this can be changed
to 5, 10 or 15 seconds with the procedure below.
Refer to section “
10.4.6 Setting up the Individual Call Ringer
” for details.
15.5 GROUP DIRECTORY
For this function to operate, the same group MMSI must be programmed into all
the DSC VHF radios within the group of vessels that will be using this feature.
Refer to section “ 10.5.1 Setting up a Group Call ” for details.
15.6 POSITION REPLY
The HX890 can be set up to automatically (default setting) or manually send
your position when requested by another vessel. This selection is important if
you are concerned about someone polling the position of your vessel that you
may not want to. In the manual mode you will see the MMSI (Maritime Mobile
Service Identity Number) or persons name shown on the display allowing you
to choose to send your position to the requesting vessel.
Refer to section “ 10.6.3 Setting up Position Reply ” for details.
