4. OPERATION
This chapter describes basic controller operation, radiotelephone communication, DSC
calling procedures, and other radiotelephone functions.
4.1 Controller operation overview
Basically, the controller is operated with the numeric keypad (10key), MENU key, and jog dial.
Following is an overview of their operation.
● When multiple controllers are connected, only one controller having 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 accessible controller.)
● To obtain the access right at an inaccessible (i.e. monitor) controller, press the jog dial or take the
handset off-hook under such condition that the accessible controller is not in use (such as taking
a handset off-hook, pressing the PTT ON, or operating menu). However note that a controller
installed as a high priority can always obtain the access right if only at the PTT OFF condition.
● The DISTRESS key is always available even when pressing at the monitor controller. (The
DISTRESS key is treated as the highest priority.)
● To verify a prepared DSC message just before sending, provides two types of verification screens:
Simple mode (shows editable information only) and Detail mode (shows every information).
● On the status display, the VHF channel number can be set whether by pressing the numeric keys
directly or by rotating the jog dial.
● On the status display, pressing the CANCEL key opens the squelch temporally to listen to the
receiving audio (or noise).
● Placing the handset back on-hook will return the channel to CH16 (factory default value). Also,
the on-hook detection can be disabled at the menu 9.3-5 Hook switch.
● All functions can be accessed using the MENU key, jog dial, and the dedicated keys/controls.
(See the menu tree of the equipment on the next page.)
● Pressing the FUNC (function) key followed by a numeric key can allow rapid access to that
function.
● Each menu can be selected by pressing the MENU key to activate the main menu, rotating the
jog dial to move the cursor to the desired item, and then pressing the jog dial to press ENT.
Alternatively, direct entering of the desired menu number is available. (e.g. To select a menu for
safety call to all ships (2.1.1 All Ships), press MENU 2SCAN 1DW 1DW .）
● If registered a desired menu on the USER key, enables to call up the menu directly.
● Pressing the CANCEL key on a menu will return to the previous menu in the hierarchy (or the
status display), or "0. Back" selection is as well. Further, pressing the CANCEL key on an
input line will clear the entered data.
● Pressing the MENU key on a hierarchical menu will return to the main menu.
Furthermore, pressing the MENU key on the main menu will return to the status display.
● While displaying menus, if the controller is left unused for 10 minutes, the condition will be
canceled and the screen will return to the status display automatically to treat the DSC receiving
message promptly.
● Opens the popup screen accordingly, and operation can be performed via dialogues.
● The screens or contents, noted by "Printable" on the menu tree of next page, can be printed out
by pressing Func & 7PRN simultaneously, if a printer has been connected to the controller.
Additionally, if not connected to the controller but the transceiver, the screen or contents will be
printed out from the printer of the transceiver.
