INSTALLATION AND CONNECTIONS

■ Unpacking

After unpacking, immediately report any damage to
the delivering carrier or dealer. Keep the shipping car-
tons.
For a description and a diagram of accessory equip-
ment included with the IC-7200, see 'Supplied acces-
sories' on page i of the printed manual.

■ Selecting a location

Select a location for the transceiver that allows ade-
quate air circulation is free from extreme heat, cold,
or vibrations, and away from TV sets, TV antenna ele-
ments, 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, de-
pending on your operating conditions.

■ Grounding

To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the transceiver through the GROUND
terminal on the rear panel.
For best results, connect a copper or copper-plated
ground rod driven into the earth. Make the distance
between the [GND] terminal and ground as short and
straight as possible.
R WARNING! NEVER
terminal to a gas or electric conduit, since the con-
nection could cause an explosion or electric shock.

■ Connecting an antenna

For radio communications, the antenna is of critical
importance for output power and sensitivity. Use well-
matched 50 ø antennas and coaxial feedline. An SWR
(standing wave ratio) of 1.5:1 or lower is recommend-
ed 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 the SWR may increase out-of-range. When the
SWR is higher than approximately 2.0:1, the trans-
ceiver's power drops to protect the final transistors.
In this case, an optional antenna tuner is useful to
match the transceiver and antenna. Low SWR allows
full power for transmitting, even when using the an-
tenna tuner. The IC-7200 has an SWR meter to con-
tinuously monitor the antenna SWR.
