SAVE THIS INSTR UCTION MANU AL— This
instruction manual contains important operating instructions
for the IC-PCR100 COMMUNICATIONS RECEIVER FOR
COMPUTER.
USE antenna(s), such as a well-matched 50 Ωantenna and
feedline. For radio communications, the antenna is of critical
importance, along with sensitivity.
SYSTEM REQUIREMENTS
•IBM PC/AT compatible computer
•An RS-232C serial port (38400 bps or faster)
•Microsoft®Windows®95 or Microsoft®Windows®98
•Intel i486DX4 processor or faster (Pentium®100 MHz or
faster recommended)
•At least 16 MB RAM
•At least 10 MB of hard disk space
•At least 640 ×480 pixel displa y (800 ×600 pixel display rec-
ommended)
OPERATING THEOR Y
Electromagnetic radiation which has frequencies of 20,000
Hz (20 kHz*) and abov e 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 w a ves. AF energy is in the range
of 20 to 20,000 Hz.
*kHz is an abbreviation of kiloher tz or 1000 her tz, MHz is abbrevia-
tion of megaher tz or 1,000,000 hertz, where her tz is a unit of fre-
quency.
OPERATING NOTES
The IC-PCR100 ma y 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.
