While plugging or unplugging any cable, make sure that
your hands are completely dry.
Do not tread on, pull or over-bend any cable. Otherwise,
the cable may be damaged, leading to malfunction of the
device.
Do not use an old or a damaged power cable.
During lightning weather, stop using the device and
disconnect it from the power supply. Unplug the power
plug and the ADSL twisted pair (the radio frequency
cable), to avoid lightning strike.
If the device is not used for a long time, disconnect it from
the power supply and unplug the power plug.
Do not look directly into the optical interface and the laser-
transmitting interface on the device, or the infrared
transmitting interface on the remote control with your eyes.
Otherwise, your eyes may be injured.
In any of the following cases, stop using the device,
disconnect it from the power supply and unplug the power
plug immediately: there is smoke emitted from the device,
or there is some abnormal noise or smell. Contact the
specified maintenance center for repair.
Avoid any object (such as metal shavings) from entering
the device from the heat dissipation intakes.
Before connecting any other cable, connect the grounding
cable of the device first. Do not disconnect the grounding
cable until you disconnect all other cables.
Make sure that the three-phase power socket is grounded
reliably. The neutral line and the live line shall not be
connected inversely.
