Error log file
The TNC stores errors and important events (e.g. system startup) in
en error log file. The capacity of the error log file is limited. If the log
file is full, the TNC uses a second log file. If this is also full, the first log
file is deleted and written to again, and so on. To view the error history,
switch between CURRENT FILE and PREVIOUS FILE.

8 To open the error log file, 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

The oldest entry is at the beginning of the error log file, and the most
recent entry is at the end.
Keystroke log file
The TNC stores keystrokes and important events (e.g. system startup)
in the keystroke log file. The capacity of the keystroke log file is
limited. If the log file is full, a second log file is created. If this second
file becomes full, the first 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 FILE 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 the keystroke log
file. The oldest entry is at the beginning of the log file, and the most
recent entry is at the end.
