2 INSTALLATION AND CONNECTIONS ■ Unpacking ■ Antenna connection 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-7600, see 'Supplied accessories' on p. i of this manual. ■ Selecting a location For radio communications, the antenna is of critical importance, along with output power and receiver sensitivity. Select antenna(s), such as a well-matched 50 ø antenna, and feedline. We recommend 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) on your operating bands. The transmission line should be a coaxial cable. When using a single antenna, use the [ANT1] connector. 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. CAUTION: Protect your transceiver from light- ning by using a lightning arrestor. 1 2 The base of the transceiver has adjustable feet for desktop use.

Unpacking
After unpack±ng, ±mmed±ately report any damage to
the del±ver±ng carr±er or dealer. Keep the sh±pp±ng
cartons.
For a descr±pt±on and a d±agram of accessory equ±p-
ment ±ncluded w±th the IC-7600, see ‘Suppl±ed acces-
sor±es’ on p. ± of th±s manual.
Selecting a location
Select a locat±on for the transce±ver that allows ade-
quate a±r c±rculat±on, free from extreme heat, cold, or
v±brat±ons, and away from TV sets, TV antenna ele-
ments, rad±os and other electromagnet±c sources.
The base of the transce±ver has adjustable feet
for desktop use. Set the feet to one of two angles
depend±ng on your operat±ng preference.
Grounding
To prevent electr±cal shock, telev±s±on ±nterference
(TVI), broadcast ±nterference (BCI) and other prob-
lems, ground the transce±ver through the GROUND
term±nal on the rear panel.
For best results, connect a heavy gauge w±re or strap
to a long ground rod. Make the d±stance between the
[GND] term±nal and ground as short as poss±ble.
R
WARNING: NEVER
connect the [GND]
term±nal to a gas or electr±c p±pe, s±nce the connec-
t±on could cause an explos±on or electr±c shock.

Antenna connection
For rad±o commun±cat±ons, the antenna ±s of cr±t±-
cal ±mportance, along w±th output power and rece±ver
sens±t±v±ty. Select antenna(s), such as a well-matched
50
ø
antenna, and feedl±ne. We recommend 1.5:1 or
better of Voltage Stand±ng Wave Rat±o (VSWR) on
your operat±ng bands. The transm±ss±on l±ne should
be a coax±al cable.
When us±ng a s±ngle antenna, use the [ANT1] con-
nector.
CAUTION:
Protect your transce±ver from l±ght-
n±ng by us±ng a l±ghtn±ng arrestor.

Antenna SWR
Each antenna ±s tuned for a spec±f±ed frequency
range and SWR may be ±ncreased out-of-range.
When the SWR ±s h±gher than approx. 2.0:1, the
transce±ver’s power drops to protect the f±nal tran-
s±stors. In th±s case, an antenna tuner ±s useful
to match the transce±ver and antenna. Low SWR
allows full power for transm±tt±ng. The IC-7600 has
an SWR meter to mon±tor the antenna SWR cont±n-
uously.
