Audio-Visual Cables
Periodically (once a week is recommended) check whether the cables connecting the terminal
to the peripheral equipment and the power supply are securely connected.
If the cables are connected properly, power on the terminal to test the connectivity. If any of
the cables are loose, connect them securely.
Communication Cables
Periodically (once a week is recommended) power on the terminal, and then check whether
the communication cables connected to the terminal work properly using the following
method:
Place calls to other terminals using different communication methods, such as accessing a
broadband network.
If a call is set up successfully, it indicates that the communication cable works properly
in the corresponding access mode.
If a call cannot be set up properly, check whether the cables are connected correctly and
securely and whether the communication parameters are set properly. If the problem
persists, contact the network administrator to check the network.
