must be clean and tight.	Black	Red
LIGHTNING PROTECTION

Consider carefully how to protect your equipment and

5	your home from lightning. Even in areas where
	lightning storms are less common, there are usually a
	limited number of storms each year. Take the time to
6	study the best way to protect your installation from the
	effects of lightning by consulting reference material on
	the subject.
	The installation of a lightning arrestor is a start, but there
7	is more that you can do. For example, terminate your
	antenna system transmission lines at an entry panel
	that you install outside your home. Ground this entry
	panel to a good outside ground, and then connect
8	appropriate feed lines between the entry panel and your
	transceiver. When a lightning storm occurs, you can
	ensure added protection by disconnecting the feed lines
	from your transceiver.
9	CAUTION: DO NOT ATTEMPT TO USE A GAS PIPE (WHICH IS
	CLEARLY DANGEROUS), AN ELECTRICAL CONDUIT (WHICH
	HAS THE WHOLE HOUSE WIRING ATTACHED AND MAY ACT
	LIKE AN ANTENNA), OR A PLASTIC WATER PIPE FOR A
	GROUND.
10	DC POWER SUPPLY CONNECTION
	In order to use this transceiver, you will need a separate
11
	13.8 V DC power supply that must be purchased
	separately. DO NOT directly connect the transceiver to
	an AC outlet! Use the supplied DC power cable to
	connect the transceiver to a regulated power supply. Do
12	not substitute a cable with smaller gauge wires. The
	current capacity of your power supply must be 20.5 A
	peak or more.
	CAUTION:
13	◆ BEFORE CONNECTING THE DC POWER SUPPLY TO THE
	TRANSCEIVER, BE SURE TO SWITCH THE TRANSCEIVER

AND THE DC POWER SUPPLY OFF.

◆DO NOT PLUG THE DC POWER SUPPLY INTO AN AC OUTLET UNTIL YOU MAKE ALL CONNECTIONS.
