CAUTIONS
RWARNING! NEVER connect the receiver to an AC
outlet. This may pose a fire hazard or result in an electric
shock.
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.
NEVER connect other than the specified AC adapter to the
receiver. This connection will ruin the 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:
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.
- 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.
AVOID the use of chemical agents such as benzine or al-
cohol when cleaning, as they damage the receiver surfaces.
- Consult the dealer or an experienced radio/TV technician for help.
Place unit in a secure place to avoid inadvertent use by children.

■ Antenna installation
■ Grounding
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.
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.
Select antenna(s), such as a well-matched 50 Ω antenna and
feedline. 1.5:1 of Voltage Standing Wave Ratio (VSWR) is rec-
ommended for a desired band. Of course, the antenna line
should be a coaxial cable.
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.
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.

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

■ Setting squelch level
■ IF filter selection
The squelch function sets a minimum receive signal level
below which no audio is emitted from the speaker. This con-
veniently prevents noise and static from being emitted when
receiving weak signals or no signals at all.
Increasing or decreasing the width of incoming signals can
help eliminate interference. Available filters vary according to
the receive mode. See the table below.
