4. OPERATION
This chapter describes basic operations of the controller and the data terminal,
radiotelephone communications, telex communications, DSC calling procedures, and
other radio functions.
4.1 Operation overview
4.1.1 Operation of the controller
Basically, the controller is operated for other than the telex communication with the numeric
keypad (10key), the
MENU key, and jog dial. The following is an overview of their operation.
z
When two controllers are connected, only one controller having the access right can operate
the radiotelephone, except for sending a distress call, changing audio volume, and changing
display conditions. (Unless otherwise mentioned, the instructions below are for the controller
with the access rights.)
z
To obtain the access right at a controller without access rights, press ENT to get the access
right unless the other controller is being operated (PTT/KEY ON or menu operations).
z
The DISTRESS key is always available even if the controller does not have the access
right. (The DISTRESS key has the highest priority.)
z
On the status display, the communication frequency or channel can be set by using the
number keys or by rotating the jog dial.
z
Pressing the TEL , DSC , or CW keys changes the communication mode and returns
the menu display to the status display. When this is done, channel input modes changes to
the free frequency mode. Additionally, setting to the AM mode to listen to the radiobroadcast,
or to the DATA mode to communicate with another ship using the intership fax are available.
z
When the communication mode is set to TEL or CW, pressing the same communication mode
key turns the PA on and off. (When the PA is on, TXON appears.)
z
All functions can be accessed using the MENU key, jog dial, and the dedicated
keys/controls. (See the menu tree on the next page.) Additionally, screens indicated by
"Printable" in the menu tree can be printed from a printer connected to the controller or the
data terminal by pressing and holding the F UN C key and then pressing the 7PRN key.
z
Pressing or pressing and holding the FUNC (function) key and a number key allows rapid
access to that function.
z
There are two ways to access main menu items. After pressing the MENU key to display
the main menu, use either the jog dial to move the cursor to the desired item and press ENT
to select it, or select the item by pressing the respective number key. (Ex: For Self diagnosis
(6.1.1 Transceiver), press MENU Î 6SP Î 1CLAR Î 1CLAR )
z
Any menu can be assigned to the USER key to quickly open it with a single touch of a
button.
z
Normally the key is always enabled.
z
The CH key's channel input mode can be changed to a User channel, ITU channel, or to a
free frequency. This key is only enabled when the status display is displayed.
z Pressing the CANCEL key in any menu moves the display up one level in the hierarchy
(or to the status display). The same results can be achieved by selecting "0. Back" when
available on-screen. Further, pressing the CANCEL key on an input line will clear the
entered data.
z
Press ing the ME NU key in any menu opens the main menu. Also, pressing M ENU
while in the main menu returns to the status display.
z
If no operations are done for 10 minutes while a menu is open, the screen automatically
returns to the status display.
z
Dialog boxes (popup screens) are opened when necessary and operations can be done in
the dialog box.
