11.5 INDIVIDUAL CALL
This feature allows the HX890 to contact another vessel with a DSC VHF radio
and automatically switch the receiving radio to a desired communications chan-
nel. This feature is similar to calling a vessel on CH16 and requesting to go to
another channel (switching to the channel is private between the two vessels).
Up to 100 individual contacts may be programmed.
11.5.1 Setting up the Individual Call Directory
The HX890 has a DSC directory that allows you to store a vessel or person’s
name and the associated MMSI number you wish to contact via individual calls,
position report, and test call transmissions.
To transmit an individual call, this directory must be programed with information
of the vessel you wish to call, similar to a cellular phones telephone directory.

11.6 GROUP CALL
The Group Call feature allows the user to contact a specific group of vessels
(e.g. members of a yacht club) using DSC radios and signal all the group to
automatically switch to the designated channel for voice communications.
This function is very useful for yacht clubs and vessels traveling together to
collectively make announcements on a predetermined channel. Up to 20 group
MMSI numbers may be programmed.
11.6.1 Setting up a Group Call
For this function to operate, the same group MMSI (Maritime Mobile Service
Identity Number) must be programmed into all the DSC VHF radios within the
group of vessels that will be using this feature. To understand Group MMSI
programming, first a ship MMSI has to be understood.
Ship MMSI: This number is assigned by the FCC, or other organization licensed
to assign ship MMSI numbers. The first three digits called MID (Mobile Identity
Group) of a vessel’s MMSI denote the country where the MMSI is registered.
The last 6 digits are specific to the ships ID.
Ship MMSI Example: If the MMSI is “366123456”, “366” is the MID which
denotes the country and “123456” is the ships MMSI.
Group MMSI:
 Group MMSI numbers are not assigned by the FCC or other organizations
   licensed to assign ship MMSI numbers.
 The first digit of a group MMSI is always set to “0” by International rules. All
   Standard Horizon radios are preset so when programming a group MMSI
   the first digit is set to “0”.
 The USCG recommends programming the MID of a ship MMSI into the
   Second, Third and Fourth digits of the group MMSI as it denotes the area
   the ship is located in.
 The last 5 digits are decided upon by the members of the group. All radios
