11.5 INDIVIDUAL CALL
This feature allows the GX3500S to contact another vessel with a DSC VHF
radio and automatically switch the receiving radio to a desired communications
channel. 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
stations).

11.5.1 Setting up the Individual / Position Call Directory

The GX3500S has a DSC directory that allows you to store a vessel or person’s
name and the MMSI number associated with vessels you wish to transmit Indi-
vidual calls, Position Requests and Position Send transmissions.
To transmit an Individual call you must program this directory with information
of the persons you wish to call, similar to a cellular phones telephone directory.
1. Press and hold down the [CALL(MENU)] key until
“Radio Setup” menu appears.
2. Turn the CHANNEL selector knob to select “DSC
Setup” menu.
3. Press the [ENT] key, then select “INDIV DIR” with the
CHANNEL selector knob.
4. Press the [ENT] key, then select “Add” with the CHAN-
NEL selector knob.
5. Press the [ENT] key.
6. Press the one of the Keypad keys to enter the first
letter of the name of the vessel or person you want to
reference in the directory.
Example: Press the [2(MEM)] key repeatedly to toggle
among the seven available characters associated
with that key: 2 A B C a b c.
If a mistake was made entering in the name, press-
ing the [CLR] key to delete the wrong character.
7. Press the [ENT] key to store the first letter in the name
and step to the next letter to the right.
8. Repeat step 6 and 7 until the name is complete. The
name can consist of up to eleven characters, if you

space. This method can also be used to enter a blank space in the name.
To clear the previous letter, press the [CLR] key.
9. After the eleventh letter or space has been entered, press the [ENT] key to
advance to the MMSI (Maritime Mobile Service Identity Number) number
