The operation of a communications system can be impaired by interference in the
power supply caused by other equipment, especially photocopiers, laser printers,
electric typewriters, air conditioning, fan heaters, vacuum cleaners and refrigerators.
For this reason, please:
• Connect the Eumex 704PC LAN to a socket as far away as possible from sockets
used for the above-mentioned equipment. The best solution is to use a separate
circuit for the Eumex 704PC LAN.
• Ensure that the AC adapter is always seated securely in its socket. Adapters or
sockets not firmly secured can lead to faulty operation and possibly fires!
Have such sources of danger repaired by qualified personnel without delay.
• Only use multiple sockets that are adequately safe. This can be assumed only if the
multiple socket displays the proof of its compliance with safety standards (e.g. the
CE symbol). Failure to observe this can lead to faulty operation of the Eumex
704PC LAN, and even fires.
Connect the Eumex 704PC LAN to the mains supply. The connector socket for the AC
adapter is on the lower side of the Eumex 704PC LAN. Insert the corresponding power
cable plug into the socket marked
, then insert the AC adapter into the mains power
socket.
When the T-ISDN LED lights up, it means that the NTBA is operational. If the LED
flashes, it means that external calls are not possible.
Now you can make and accept internal and external calls. In this setting, incoming
calls are signalled simultaneously on all terminals. External calls can only be made to
specific terminals when you have assigned them MSNs. Please refer to the chapter
entitled "Configuring the System" for information on this procedure.
In the case of faulty operation, please also refer to the notes in the Appendix (p. 110).
