INSTALLATION AND CONNECTIONS

■ Unpacking

After unpacking, immediately report any damage to
the delivering carrier or dealer. Keep the shipping
cartons.
For a description and a diagram of accessor y
equipment included with the IC-7000, see 'Supplied
accessories' on p. i-1 of this manual.

■ Selecting a location

Select a location for the transceiver that allows
adequate air circulation, free from extreme heat, cold,
or vibrations, and away from TV sets, TV antenna
elements, radios and other electromagnetic sources.
The base of the transceiver has an adjustable
stand for desktop use. Set the stand to one of two
angles depending on your operating conditions. (see
description on right hand page)

■ Grounding

To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other
problems, ground the transceiver through the
GROUND terminal on the rear panel.
For best results, connect a heavy gauge wire or
strap to a long, buried copper rod. Make the distance
between the [GND] terminal and ground as short as
possible.
R WARNING! NEVER
terminal to a gas pipe or electric conduit, since the
connection could cause an explosion or electric
shock.

■ Antenna connection

For radio communications the antenna is of critical
importance for output power and sensitivity. Use well-
matched 50-ohm antennas and coaxial feedline.
An SWR (standing wave radio) of 1.5:1 or lower is
recommended when transmitting.
CAUTION:
Protect your transceiver from
lightning by using a lightning arrestor.

ANTENNA SWR
Each antenna is tuned for a specified frequency
range and SWR increases outside that range.
When the SWR is higher than approx. 2.0 : 1,
the transceiver's power drops to protect the final
transistors. In this case, an antenna tuner is used
to match the transceiver and antenna. Low SWR
allows full power for transmitting even when using
the antenna tuner. The IC-7000 has an SWR meter
to monitor the antenna SWR continuously.
