Figure 2-1. TCP Screen
NOTE: The SAT PHONE 1/2 menu shown in Figure 2-1 is an example where classic (SAT-1) and
SBB (SAT-2) cockpit calls are supported. Depending on the secure ORT parameter
settings, the prompts “SAT-1” and “SAT-2” can be replaced to display any message limited
to five characters.
The top of the screen displays the title of the menu on the screen. The bottom of the screen
(Line 14) is the scratchpad that displays information that you enter on the keyboard.
The TCP has four buttons on each side of the screen that activate TCP functions. Figure 2-1
displays these buttons on the left and right sides of the screen. When the functions
corresponding to a button are available, the function is displayed beside the button.
Other lines on the TCP screen display information relevant to the function or status of the
A781-500 system.
When a button has an action associated, there will be either a < or > symbol beside it.
(2) Keyboard
The TCP’s keyboard includes a set of numeric keys and a set of alphabetic keys, both of
which you can use to enter data into the TCP.
The keyboard may include preset keys, such as the following:
•The IDX or MAIN MENU key: this key returns you to the TCP’s main menu.
•The CLR key: this key clears any text you type into the scratchpad.
•The NEXT PAGE key: this key brings up the next page of a menu if one is available.
•The PREV PAGE key: this key brings up the previous page of a menu if one is available.
