IMPORTANT SAFETY INFORMATION
1. Components inside your appliance are subject to high Voltage. Do not
ever open it, even after having removed the power cable. Generally
speaking, audio &video appliances are not connected to the earth, you
may then feel electric shocks (not dangerous) when touching both
appliances simultaneously (or one appliance and the antenna cable). We
advise to plug the appliances on the mains after having connected
everything.
2. Do not use solvent or detergent to clean up your terminal or remote
control. A dry cloth will perfectly remove dust.
3. Do not put the receiver close to other appliances. Choose a
well-ventilated place and do not put anything on the ventilation grid. Do
not ever put the receiver on another appliance; the overheating would
prematurely damage the components.
4. When there is storm, unplug all your audio-video appliances from the
mains: they could suffer damages not covered by manufacturer’s
warranty.
5. According to the obligations pursuant to EN 60065 standard, we draw
your attention onto the safety elements below. Do not block the
ventilation holes with paper, tablecloths, curtains, etc. A minimum
distance of 5cm is required around the appliance to ensure enough
ventilation.
6. Do not put naked fire sources on or close to the appliance, such as lit
candles. The appliance shall not be exposed to water dripping or splash.
Do not put things filled with water such as vases onto the appliance.
7. The remote control requires two AAA 1.5V batteries. Please follow the
polarity instructions written inside it. To respect environment and law,
please never throw out used batteries with household refuse.
8. In order to work properly, the appliance needs to be used according to
the instructions.
