2 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 accessory 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 connect the [GND] 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 wellmatched 50-ohm antennas and coaxial feedline. An SWR (standing wave radio) of 1.5:1 or lower is recommended when transmitting.

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. 15

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 accessory
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.

WARNING! NEVER
connect the
[GND]
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.
