Important Information
Caution: Unauthorised changes to the device can damage the PBX or breach
security and EMC regulations. If security-relevant radio services are disrupted, the
Federal Network Agency can order the decommissioning of the device in accordance
with §14, section 6, Electromagnetic Compatibility Act.
• Always have a professional carry out repairs. Please contact your qualified electrician or
the manufacturer directly.
Caution: Exceeding (even temporarily) the threshold values indicated in the technical
data can damage or even destroy the PBX.
• Note the threshold values indicated in the technical data for voltage, electricity,
performance, ambient temperature, and moisture.
• COMmander 6000: Never cover the vent slots of the casing.
• COMmander 6000R/RX: Make sure not to cover the fan on the rear side of the casing.
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.
