SAVE THIS INSTRUCTION MANUAL— This
instruction manual contains important operating instructions
for the IC-PCR100 COMMUNICATIONS RECEIVER FOR
COMPUTER.
USEantenna(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 display (800 ×600 pixel display rec-
ommended)
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.

CAUTIONS
RWARNING! NEVER connect the receiver to an AC
outlet. This may pose a fire hazard or result in an electric
shock.
NEVER connect other than the specified AC adapter to the
receiver. This connection will ruin the receiver.
NEVER connect the receiver to a power source of more
than 16 V DC such as a 24 V battery. This connection will ruin
the receiver.
NEVER expose the receiver to rain, snow or any liquids.
DO NOT use or place the receiver in areas with tempera-
tures below 0°C (+32°F) or above +50°C (+122°F) or, in areas
subject to direct sunlight.
AVOID placing the receiver in excessively dusty environ-
ments.
AVOID the use of chemical agents such as benzine or al-
cohol when cleaning, as they damage the receiver surfaces.
Place unit in a secure place to avoid inadvertent use by children.
For U.S.A. only (FCC information)
CAUTION: Changes or modifications not expressly ap-
proved by Icom Inc. could void the user’s authority to operate
this receiver.
Class B digital device users
This equipment has been tested and found to comply with the limits
for Class B digital devices, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment gen-
erates, uses and can radiate radio frequency energy and, if not in-
stalled and used in accordance with the instruction manual, may
cause harmful interference to radio communications. However, there
is no guarantee that interference will not occur in a particular installa-
tion. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equip-
ment off and on, the user is encouraged to try to correct the interfer-
ence 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 different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
For Canada only
Operation is subject to the following two conditions: (1) this device
may not cause interference, and (2) this device must accept any in-
terference, including interference that may cause undesired opera-
tion of the device. ii

■Antenna installation
Antennas play a very important role in receiver operation.
Connecting a poor quality antenna to the IC-PCR100 will re-
sult in less than optimum performance.
Select antenna(s), such as a well-matched 50 Ωantenna and
feedline. 1.5:1 ofVoltage Standing Wave Ratio (VSWR) is rec-
ommended for a desired band. Of course, the antenna line
should be a coaxial cable.
CAUTION: Protect your receiver from lightning by
using a lightning arrestor.
NOTE: The supplied antenna is a simple plain antenna which
may not obtain indicated specifications. To obtain maximum
performance from the IC-PCR100, you must purchase an ex-
ternal wide band antenna such as an optional Icom AH-7000
(25–1300 MHz), etc.
Contact your nearest Icom Dealer or Service Center for re-
garding optimum antenna locations.
The antenna connector type is BNC, so an adapter may be
necessary to connect an optional antenna.
■Grounding
RWARNING: NEVER use a gas pipe or electrical
conduit pipe for grounding.
To prevent accidents involving electricity and interference
from computers, ground the receiver through the GROUND
terminal on the rear panel.
For best results, connect a heavy gauge cable to a water pipe
or long, earth-sunk copper rod. Make the distance between
the [GND] terminal and ground as short as possible.
