point where they exit from the apparatus.
• Only use attachments/accessories specified by the manufacturer.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any
way, such as the power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

• The main plug is the main disconnect device. It shall remain readily accessible and operable.
• The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases, shall be
placed on the apparatus.
• Transport the cable terminal in its shipping box or an equally padded container.
• Do not expose the terminal to rain or moisture.
• Do not place the terminal in an enclosed area where the cooling vents are blocked or impede the flow of air through
the ventilation openings.
•Install the terminal so that its position does not interfere with its proper ventilation. For example, do not place the
terminal on a bed, sofa, rug, or similar surface that could block the ventilation openings.
•Install the terminal away from heat sources such as radiators, heat registers and stoves. Installation of the terminal
near consumer electronics devices, such as stereo receiver/amplifiers and televisions, is permitted as long as the air
surrounding the terminal does not exceed 40º C (104º F).
• Place the terminal on a flat surface not prone to vibration or impact.
• Do not install the terminal in an area where condensation occurs.
• To prevent the temporary loss of guide data and cause a temporarily non-responding terminal, do not plug the AC
power cord into a switched power outlet.
