READ ALL INSTRUCTIONS carefully and com-

pletely before using the receiver.

SA VE THIS INSTRUCTION MANUAL— This

instruction manual contains important operating instructions
for the IC-PCR100 COMMUNICATIONS RECEIVER FOR

COMPUTER.

USEantenna(s), such as a w ell-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 rec­ommended)

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

* kHz is an abbreviation of kilohertz or 1000 her tz, MHz is abbrevia-

tion of megahertz or 1,000,000 her tz, where hertz is a unit of fre ­quency.

OPERATING NOTES

The IC-PCR100 may receive its o wn oscillated frequency, re­sulting in no reception or only noise reception, on some fre­quencies.

The IC-PCR100 may receive interference from extremely
strong signals on different frequencies or when using an ex­ternal high-gain antenna.

Versions of the IC-PCR100 which display “CE” on the serial num­ber 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 NOTuse 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 gen­erates, uses and can radiate radio frequency energy and, if not in­stalled 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 installa­tion. 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 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 in­terference, including interference that may cause undesired opera­tion of the device.

INSTALLATION

■ Antenna installation

Antennas play a very important role in receiver operation.
Connecting a poor quality antenna to the IC-PCR100 will re­sult in less than optimum performance.

Select antenna(s), such as a well-matched 50 Ω antenna and
feedline. 1.5:1 of Voltage Standing Wave Ratio (VSWR) is rec­ommended 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 ex­ternal wide band antenna such as an optional Icom AH-7000
(25–1300 MHz), etc.

Contact your nearest Icom Dealer or Service Center for re­garding optimum antenna locations.

The antenna connector type is BNC, so an adapter ma y be
necessary to connect an optional antenna.

■ Grounding

R WARNING: 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 w ater pipe
or long, earth-sunk copper rod. Make the distance between
the [GND] terminal and ground as short as possible.

■ Setting a tuning step

When using the tuning dial or [FREQJ]/[FREQK] buttons to
change the frequency, or when a scan function is activated,
the frequency changes in increments determined by the set
tuning step.This can be changed if desired.

The following tuning step are available.

•1 kHz •5 kHz •6.25 kHz•9 kHz •10 kHz •12.5 kHz

•15 kHz •20 kHz •25 kHz •30 kHz •50 kHz •100 kHz

•500 kHz •1 MHz •10 MHz

■ Receive mode selection

Receive modes are determined by the physical properties of
the radio signals.The receiver has 3 receive modes:FM, AM
and WFM modes.

Typically, AM mode is used for the AM broadcast stations
(0.495–1.620 MHz) and air band (118–135.995 MHz), and
WFM is used for FM broadcast stations (76–107.9 MHz).

When using the automatic mode function, a receive mode,
tuning step and filter selection are automatically selected after
inputting a frequency.

D Using the multi-function receiver screen

➥Click [FM], [WFM], [AM] or [A UT-M] to select the desired re-

BASIC OPERATION

■ Setting squelch level

The squelch function sets a minimum receive signal level
below which no audio is emitted from the speaker. This con­veniently prevents noise and static from being emitted when
receiving weak signals or no signals at all.

Further setting of squelch removes weak signals.The remove
level is displayed on the S-meter (S-meter squelch). The
squelch does not open if a signal below the set S-meter level
is received.

TONE SQUELCH OPERATION

The tone squelch opens only when receiving a signal con­taining a matching subaudible tone in FM mode. For exam­ple, you can silently wait for calls from group members using
the same tone in an amateur band.

D Using the multi-function receiver screen

q Click the [FM] button to select FM mode.
w Click the [T-SQL] button to bring up the [TONE SQUELCH]

dialog box.

•“T-SQL” appears in the function display.

e Click the [$] button, then select the desired tone squelch

frequency.

•Fifty-one tone frequencies from 67.0 to 254.1 Hz are available.

r Click the close (["]) button to close the [TONE SQUELCH]

dialog box.

t When the received signal includes a matching tone,

squelch opens and the signal can be heard.

•When the received signal’s tone does not match, tone squelch
does not open, however, the S-indicator shows signal strength.

y Click the [T-SQL] button to cancel the tone squelch.

•“T-SQL” disappears.

D Using the simple function receiver screen

q Click [MENU] and select the ‘Function Controller’ when it

is not displayed.
