2 INSTALLATION
GROUND CONNECTION
At the minimum, a good DC ground is required to prevent such dangers as electric shock. For superior communications results, a good RF ground is required, against which the antenna system can operate. Both of these conditions can be met by providing a good earth ground for your station. Bury one or more ground rods, or a large copper plate under the ground, and connect this to the transceiver GND terminal. Use heavy gauge wire or a copper strap, cut as short as possible, for this connection. Just as for antenna work, all connections must be clean and tight.
LIGHTNING PROTECTION
Consider carefully how to protect your equipment and your home from lightning. Even in areas where lightning storms are less common, there is usually a limited number of storms each year. Take the time to 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 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 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.
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.
DC POWER SUPPLY CONNECTION
In order to use this transceiver, you will need a separate
13.8V 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 not substitute a cable with smaller gauge wires. The current capacity of your power supply must be 20.5 A or more.
CAUTION:
◆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.
◆This transceiver has not been tested for use in mobile applications.
First connect the DC power cable to the regulated DC power supply and check that polarities are correct (Red: positive, Black: negative). Then connect the connectorized end of the DC power cable to the
DC 13.8 V power connector on the transceiver Rear Panel. Press the DC power cable connector firmly into the connector on the transceiver until the locking tab clicks.

REPLACING FUSES
If the fuse blows, determine the cause then correct the problem. After the problem is resolved, only then replace the fuse. If newly installed fuses continue to blow, disconnect the power plug and contact your dealer or nearest Service Center for assistance.
