Important Safeguards
12. Use only with the cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid in-
jury from tip-over.
13. Unplug this apparatus during lightning storms or
when unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been damaged in any way, such
as 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.
15. If an outside antenna or cable system is connected to the product, be sure the
antenna or cable system is grounded so as to provide some protection against
voltage surges and built-up static charges. Section 810 of the National Electrical
Code, ANSI/NFPA No. 70-1984 (Section 54 of Canadian Electrical Code, Part 1)
provides information with respect to proper grounding of the mast and support-
ing structure, grounding of the lead-in wire to an antenna-discharge unit, size of
grounding conductors, location of antenna-discharge unit, connection to ground-
ing electrode. See following example.
16. Mains plug is used as the disconnect device. It shall remain readily operable
and should not be obstructed during intended use.
