4.2 Startup Process
All LEDs in the terminal are initially lit when the power is applied. A system-test is
then performed that includes testing and initialization of the modules in the oper-
ating terminal. Various system and error messages may be output during this sys-
tem-test. If the application memory contains a valid user description, the first mask,
the Start-Mask, or the mask specified in the language parameters as the mask to
be used as the Start-Mask will appear on the display.
This mask is displayed for 5 seconds (fixed time setting). This time can be used by
the operator to visually inspect the LEDs and the screen for proper functioning.
After this time period, the Main Mask or the mask specified in the language para-
meters as the Main Mask is displayed. This mask is the first mask of the operator
guidance.
If the Enter key is pressed while the Startup Mask is displayed, the Setup Mask will
appear on the display. This Setup Mask can be used to set the parameters for the
interface and the operating terminal.
If the Enter key is pressed before the Startup Mask is displayed, an error message
will be generated during the keyboard test.
. . . . . . .The self-test performed on the keyboard during
the terminal start-up has detected that a key is
pressed. Comply with the request and release
the key. If this message is generated when no
key is pressed, this indicates a defective key-
board. Generally, the message will disappear
after releasing the key/keys.
A longer delay may occur before the Startup Mask is displayed if the statistics
memory contains a large number of messages from the serial message system.
This time period (initialization period) is required to set up the structures for mes-
sage management, which will then enable faster sorting of messages later. During
the initialization phase, the following message is displayed:
. . . . . . .When the terminal is switched on, the mes-
sages that are present in the terminal are sort-
ed. This process requires a certain length of
time (initialization time).
