Caution: Electrostatic charges can destroy sensitive components.
• Divert electrostatic charges from yourself before touching the circuit boards with
your hands or any tools. To do this, touch a metal object, preferably earthed, such as the
PBX's earthing terminal, the 19" casing, or a computer casing.
Important: Mechanical loads and electro-magnetic fields can impair the PBX operation.
• Avoid mechanical loads (e. g. vibrations).
• Avoid the proximity of devices that generate electro-magnetic fields (e.g. radio sets,
professional radio equipment, amateur radio equipment, mobile phones, DECT systems,
etc.).
• Do not expose the device to direct sunlight.
• Protect the PBX from dirt, excessive dust, condensation caustic liquids and steam.
• Note the values for ambient temperature and humidity indicated in the technical data.
Important: A power failure, damaged connection lines and power sockets, or short-circuits
in other devices in the building services can put the PBX out of operation.
• If you have an uninterruptible power supply, you can continue operating the majority of the
system during a power failure.
• If possible, provide a separate electric circuit for the connection that supplies the PBX.
Important: Take suitable measures for protecting your data and the PBX against misuse.
• Prevent unauthorised access to the PBX and its programming.
• Never tell anyone the user names, passwords, PINs, or the public IP address of the PBX.
This applies to postings in forums and communities, router service logs and Wireshark
traces.
• Consistently use all available options for assigning passwords. Do not use passwords that
are easy to guess, such as birthdays or anniversaries.
• Use the available permissions (programming authorisation, exchange line authorisations,
restricted numbers, etc.).
• Check your PBX's call data management and your NAT router's LOGs regularly for
inconsistencies.
• You will find more information about protecting the system from misuse on the Internet
pages on the pages of the German Federal Office for Information Security (see
www.bsi.bund.de, with search term TK-Anlagen).
Proper Use
Important: The device is not designed, manufactured, or intended for use or resale, in
environments that require fail-safe performance, such as in the operation of life-support
systems and/or nuclear facilities. The device may only be used for these purposes with prior
written permission from the manufacturer in each individual case.
Important: Improper use may cause, for example, functional restrictions or interference, the
destruction of the device or, in a worst-case scenario, personal injury.
