■ 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 equip-

ment included with the IC-7600, 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 adjustable feet

for desktop use. Set the feet to one of two angles

depending on your operating preference.

■ 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 heavy gauge wire or strap

to a long ground rod. Make the distance between the

[GND] terminal and ground as short as possible.

R WARNING: NEVER connect the [GND]

terminal to a gas or electric pipe, since the connec-

tion could cause an explosion or electric shock.

■ Antenna connection

For radio communications, the antenna is of criti-

cal 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] con-

nector.

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 tran-

sistors. In this case, an antenna tuner is useful

to match the transceiver and antenna. Low SWR

allows full power for transmitting. The IC-7600 has

an SWR meter to monitor the antenna SWR contin-

uously.
