the manufacturer, or sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus combination to
avoid injury from tip-over.

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 supporting structure, grounding of the lead-in wire to an antenna-discharge
