HEXADECIMAL FORMAT IN
HISTORY MODE
You can use the hexadecimal
format of History mode to see
more detailed message
information than is displayed in
the normal format.
The selected Directory Number
value, call status code, and
information element codes are
displayed, as well as the
abbreviated message and call
reference number.
In the hexadecimal format, you
can view only one message at a
time. To see another message,
you must press the NORMAL
softkey to return to normal format,
use ROLL-UP and ROLL-DOWN
to display another message on
the screen, and then press the
HEX softkey to return to
hexadecimal format.
The screens that follow are an
example of a message in the
hexadecimal format of History
mode. Line 4 of the displays
shows the names of softkey
functions specific to History
mode. Use the softkeys ROLL-UP
and ROLL-DOWN to scroll
through the lines of the message.
The softkey NORMAL switches
the display back to normal format,
and EXIT leaves History mode.
