FCC INFORMATION

• FOR CLASS B UNINTENTIONAL RADIATORS:

This equipment has been tested and found to comply with

the limits for a Class B digital device, pursuant to part 15 of

the FCC Rules. These limits are designed to provide reason-

able protection against harmful interference in a residential

installation. This equipment generates, uses and can radi-

ate radio frequency energy and, if not installed and used in

accordance with the instructions, may cause harmful inter-

ference to radio communications. However, there is no guar-

antee that interference will not occur in a particular instal-

lation. If this equipment does cause harmful interference to

radio or television reception, which can be determined by

turning the equipment off and on, the user is encouraged to

try to correct the interference by one or more of the following

measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and

receiver.

• Connect the equipment into an outlet on a circuit differ-

ent from that to which the receiver is connected.

• Consult the dealer or an experienced radio/TV techni-

cian for help.

OPERATING THEORY

Electromagnetic radiation, which has frequencies of

20,000 Hz (20 kHz*) and above, is called radio frequency

(RF) energy because, it is useful in radio transmissions. The

IC-R6 receives RF energy from 0.100 MHz* to 1309.995

MHz and converts it into audio frequency (AF) energy which

in turn actuates a loudspeaker to create sound waves.

AF energy is in the range of 20 to 20,000 Hz.

* kHz is an abbreviation of kilohertz or 1000 hertz, MHz is abbrevi-

ation of megahertz or 1,000,000 hertz, where hertz is a unit of fre-

quency.

OPERATING NOTES

The IC-R6 may receive its own oscillated frequency, result-

ing in no reception or only noise reception, on some fre-

quencies.

The IC-R6 may receive interference from extremely strong

signals on different frequencies or when using an external

high-gain antenna.

CAUTION: Changes or modiﬁcations to this device, not

expressly approved by Icom Inc., could void your authority

to operate this device under FCC regulations.
