Safety
12.Use only with the cart, stand, tripod, bracket, or table specified by the manufac-
turer, or sold with the apparatus. When a cart is used, use caution when moving the
cart/apparatus combination to avoid injury 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. Sec-
tion 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 supporting struc-
ture, grounding of the lead-in wire to an antenna-discharge unit, size of grounding conductors, location of
antenna-discharge unit, connection to grounding electrode. See following example.
