Installation And Connections; Unpacking; Selecting A Location; Grounding - Icom IC-7200 Instruction Manual

■ 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 p. i of this manual.

■ Selecting a location

Select a location for the transceiver that allows ade-
quate air circulation, 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
depending 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.

INSTALLATION AND CONNECTIONS

■ Antenna connection

For radio communications the antenna is of criti-
cal 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 recom-
mended when transmitting.
CAUTION:
Protect your transceiver from light-
ning by using a lightning arrestor.

Antenna SWR
Each antenna is tuned for a specified frequency
range and SWR may be increased out-of-range.
When the SWR is higher than approx. 2.0:1, the
transceiver's power drops to protect the final transis-
tor. In this case, an optional antenna tuner is useful
to match the transceiver and antenna. Low SWR al-
lows full power for transmitting even when using the
antenna tuner. The IC-7200 has an SWR meter to
monitor the antenna SWR continuously.
