Restarting in Safe Mode

If the PanelView Plus terminal is configured to enter Configuration
Mode at startup and does not, then reload the firmware. See page 7-1
for details.
If the application does not start, there may be a problem with the .mer
RSView Machine Edition file. Check for a startup screen and
compatible version.
Safe Mode is a diagnostics mode where the terminal is reduced to a
known state that permits recovery from a configuration or application
problem. Safe Mode ignores all user changes to the system and avoids
any problems that are due to interactions with end-user software or
changes. Once the system is running in Safe Mode, you can repair the
offending applications or changes that caused the problem.
When the PanelView Plus terminal is restarted in Safe Mode, the
following occurs:
• The last configuration or the default configuration is used. The
last configuration is restored at the next reboot unless the
default configuration is saved (flushed), in which case it
becomes the new Persistent Registry.
• Depending on the state of the system, the touch screen may be
calibrated at startup.
To restart in Safe Mode:
The switches that control Safe Mode are located on the right side of
the Logic Module above the Compact Flash card slot.
• Insert a thin probe into the hole marked DEFAULT and press the
switch, then;
• Insert the probe into the hole marked RESET and press the
switch. The system will restart immediately into the Safe Mode
