METTLER TOLEDO IND890 Quick Guide
If an infection of the IND890 occurs despite all the protective measures, important data may be
lost. To minimize damage, you should regularly create backup copies of your files on a CD-
ROM/DVD or external hard drives.
If you are using transmission technologies such as Voice over IP (VoIP) or Wireless LAN
(WLAN), it is recommended that you encode your communication so that third parties cannot
read the transmission of your data or listen in to your conversations.
If an infection of the IND890 still occurs despite all the protective measures, important data
may be lost. To keep the damage as low as possible, you should regularly create backup
copies of your files on a CD-ROM/DVD or external hard drives.
Select a stable, vibration-free surface.
Ensure that no extreme temperature fluctuations occur and that the terminal is not exposed to
direct sunlight.
Avoid any draft (e.g. from fans or an air-conditioning system).
Readjust the terminal after all major changes to the geographical position (recalibration).
