READ ALL INSTRUCTIONS carefully and com-
pletely before using the receiver.
SAVE THIS INSTRUCTION MANUAL— This
instruction manual contains important operating instructions
for the IC-PCR100 COMMUNICATIONS RECEIVER FOR
COMPUTER.
USE antenna(s), such as a well-matched 50 Ω antenna and
feedline. For radio communications, the antenna is of critical
importance, along with sensitivity.

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-PCR100
receives RF energy from 0.5 MHz* to 1300 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 abbrevia-
tion of megahertz or 1,000,000 hertz, where hertz is a unit of fre-
quency.
OPERATING NOTES
The IC-PCR100 may receive its own oscillated frequency, re-
sulting in no reception or only noise reception, on some fre-
quencies.
The IC-PCR100 may receive interference from extremely
strong signals on different frequencies or when using an ex-
ternal high-gain antenna.
Versions of the IC-PCR100 which display “CE” on the serial num-
ber seal, comply with the essential requirements of the
89/336/EEC directive for Electromagnetic Compatibility.
