Error log
The TNC stores errors and important events (e.g. system startup) in an
error log. The capacity of the error log is limited. If the log is full, the
TNC uses a second file. If this is also full, the first error log is deleted
and written to again, and so on. To view the error history, switch
between CURRENT FILE and PREVIOUS FILE.
8 Open the error window.
8 Press the LOG FILES soft key.
8 To open the error log, press the ERROR LOG FILE soft
key.
8 If you need the previous log file, press the PREVIOUS
FILE soft key.
8 If you need the current log file, press the CURRENT
FILE soft key.
The oldest entry is at the beginning of the error log file, and the most
recent entry is at the end.
Keystroke log
The TNC stores keystrokes and important events (e.g. system startup)
in a keystroke log. The capacity of the keystroke log is limited. If the
keystroke log is full, the control switches to a second keystroke log. If
this second file becomes full, the first keystroke log is cleared and
written to again, and so on. To view the keystroke history, switch
between CURRENT FILE and PREVIOUS FILE.
8 Press the LOG FILES soft key.
8 To open the keystroke log file, press the KEYSTROKE
LOG FILE soft key.
8 If you need the previous log file, press the PREVIOUS
FILE soft key.
8 If you need the current log file, press the CURRENT
FILE soft key.
The TNC saves each key pressed during operation in a keystroke log.
The oldest entry is at the beginning, and the most recent entry is at
the end of the file.
