IC-Rl
WIDEBAND RECEIVER

IMPORTANT
READ ALL INSTRUCTIONS carefully and
completely before using the IC-R1.
SAVE THIS INSTRUCTION MANUAL -
This instruction manual contains important safety and oper-
ating instructions for the IC-R1.
The use of non-lcom battery packs/chargers may impair
transceiver performance and invalidatethe warranty.
OPERATING NOTES
Information overheard through the IC-R1, but not intended
for you, cannot be lawfully used in any way.
The IC-R1 may receive its own oscillated frequency, result-
ing in no reception or only noise reception, on some fre-
quencies.
The IC-R1 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.
CAUTIONS
NEVER connect a non-recommended charger. This
may result in a fire hazard or an electric shock.
NEVER connect more than a 16 V DC power source to
the receiver. This will ruin the receiver.
DO NOT use or place the receiver in areas with temper-
atures below -10°C (+ 14"F) or over +60°C (+140"F).
AVOID the use of strong chemical agents such as
benzine or alcohol when cleaning, as they may damage the
receiver surfaces.

FOREWORD
Thank -you for purchasing the IC-R1 WIDEBAND
RECEIVER, a state-of-the-art handheld receiver made
with Icom's most advanced technology.
The IC-R1 has the following features:
• Incredibly compact size and weight including the inter-
nal NiCd battery .
• Wideband frequency coverage
0.1-1300 MHz"· .• in AM, FM and Wide FM modes .
•, Guaranteed range: 2-905 MHz. Some versions do not have
the full range because of frequency restrictions .
.• MHz is an abbreviation of megahertz or 1.000.000 hertz.
where hertz is a unit of frequency.
INFO
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-R1 receives RF energy and converts it into audio fre-
quency (AF) energy which in turn actuates a loudspeaker to
create sound waves. AF energy is in the range of
20-20,000 Hz.

1 Charge .the battery.
Connect the supplied wall charger
as illustrated in the diagram be-
low.
• The CPU backup battery will also be
fully charged.
• See p. 9 for details on safety and
use of a desktop charger.
• NEVER attempt to charge a
battery case containing dry cell
(i.e. non-rechargeable) batter-
ies.
PRE-OPERATION
2 Reset the receiver.
When first applying power, the internal recharge-
able backup battery may be empty. In this case,
before you can operate the receiver, the following
reset procedure must be performed. While push-
ing [F] and [Cl.] , rotate [PWRNOll to turn power
ON.
_-"-="I-I---[PWRNO L]
• The display returns to its factory-shipped default
settings. (see p. 51)
CAUTION: Resetting the CPU will clear and
initialize all memory channel contents, pro-
grammed scan edge frequency bands, SET mode
settings and clock and timer settings.
3 Connect the
antenna.
Insert the supplied antenna
into the antenna connector
and rotate the antenna as
shown in the diagram below.
Do not remove the attached
rubber cap as it helps pre-
vent dust from entering the
receiver.

BATTERY CHARGING
The IC-R1's internal battery is a re-
chargeable NiCd and can typically be
recharged up to 300 times (approx.)
Charge the internal battery when the
low battery indicator, • (;] , appears.
• When using the receiver without an op-
tional attached battery pack or case the
internal battery provides about 2-3 hrs. of
operation (with a continuous signal. such
as a broadcast. at medium audio output) .
• When using the receiver with an optional
battery pack or case, the operating times
vary with the capacity of the pack or
batteries used with the case. When the
attached battery pack or case becomes
exhausted, remove it and continue opera-
tion using the internal battery.
NOTE: When an optional battery pack
is attached, the internal battery cannot
be Charged.
CAUTION: Never attempt to charge a
battery case containing non-
rechargeable batteries.

BATTERY CHARGING 3
• Using your battery wisely
Overcharging and complete discharging
may shorten the life of a battery.
Recharging can usually be performed
300 times, but battery life can be
lengthened to about 500 recharges as
follows:
1. Avoid overcharging. The charging
period should be less than 48 hours.
2. Use the battery until it is almost com-
pletely discharged under normal con-
ditions. We recommend battery
charging as soon as the low battery
indicator appears.
NEVER connect two or more chargers at
the same time.
Be sure to turn the receiver power OFF
during charging .
.Charging may not occur in extreme cold
(under O°C; +32 OF) or extreme heat
(over +40°C; +104 OF). 10

ACCESSORY ATTACHMENT
Handstrap
The handstrap facilitates carrying the
receiver.
Insert the end of the handstap through
the projecting loop on the receiver
using a pointed instrument, such as a
mechanical pencil.
Then, put one end of the handstrap
through the other end's loop and tight-
en as shown above.
Bottom cap removal
Belt clip
Remove the bottom cap when attach-
ing an optional battery pack or when
rapid charging the internal battery with
the BC-72.
Push the battery pack release button
upwards, then slide the bottom cap to
the right with the receiver facing you.
This enables you to attach an optional
battery pack.
The belt clip allows you to attach the
receiver to your belt.
Remove the 2 plastic screws on the
rear of the receiver, then attach the
belt clip using the supplied metal
screws.

• General
Operating the IC-R1 is easy. However, in
order to get the most out of its operating
potential, please go through the following
procedures, step-by-step. Then, try the
examples contained at the end of this chap-
ter.
What Is VFO?
The IC-R1 has several modes for opera-
tion, each of which has its own distinct
functions. VFO (Variable Frequency Opera-
tion) is one of these modes.
VFO mode is used to change the operating
frequency, receive mode, tuning step, etc.
Therefore, for most everyday operations of
the receiver, you will be using VFO mode.
BASIC OPERATION
Rotate the [PWRNOLj control clock-
wise, until a 'click' is heard.
2 Adjust the volume.
Adust the audio to a suitable level
using the [PWRNOLj control.
• Check the squelch position when no
audio is emitted. (see box at right)
• Selecting VFO mode
r---------------------~
1 Turn power ON. 3 Adjust the squelch.
Rotate the [SQUELCH] control max.
counterclockwise, then rotate it clock-
wise until audio noise is just muted
when receiving no signal.
• The [RX) indicator goes out.
What Is squelch?
A squelch circuit allows you to mute
undesired noise while receiving no
signal and emit audio while receiving
signals. This provides quiet standby.
• The [MONI) switch bypasses the mute
circuit without changing the squelch set-
ting. This is useful for weak signal
reception. (see p. 45)

The IC-R1 receives the 3 most common
modes: AM, FM and W FM. When you

It is important to set the proper tuning
step for the type of station you want to
listen to. Some tuning steps are deter-
mined by frequency band or receive
mode and others are set by tradition.
Generally speaking, if you set a tuning
step smaller than that needed you will
still be able to tune the station you want
(or scan it), however, tuning (or scann-
ing) will not be as efficient. On the other
hand, if you select a tuning step which is
too large, you may not be able to find the
station you are looking for.

All signals have what is called an "occu-
pied bandwidth." They will be received
as long as the receiver is tuned any-
where within this bandwidth, even though
the frequency received may not be the
central frequency. In order to tune to the
central frequency, the tuning step should
be made as small as possible (0.5 or 5
kHz) and the receiver tuned to the point
of greatest S indicator deflection.
To change frequencies faster than the

• Dial select steps
• What are dial select steps?
When tuning with the tuning control
and you want to change the frequency
faster than the selected tuning step,
use the dial select function.
A dial select step is an increment of
frequency change much like a tuning
step is. Unlike a tuning step however, a
dial select step has no relation to the
type of station you want to tune or to
the scan operations.
Dial select steps are available for 100
