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-R10 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 abbreviation
of megahertz or 1,000,000 hertz, where hertz is a unit of frequency.
OPERATING NOTES
The IC-R10 may receives its own oscillated frequency, resulting in no reception or only noise reception, on some frequencies.
The IC-R10 may receive interference from extremely strong
signals on different frequencies or when using an external
high-gain antenna.

Ni-Cd BATTERIES AND ACCESSORIES
■ Charging Ni-Cd batteries
The supplied Ni-Cd batteries are rechargeable and can be
charged approx. 300 times. Charge the batteries before first
operating the receiver or when the batteries become exhausted.
If you want to be able to charge the batteries more than 300
times, the following points should be observed:
1. Avoid overcharging. The charging period should be less
than 48 hours.
2. Use the batteries until they become almost completely exhausted under normal conditions. We recommend battery
charging just after receiving becomes impossible.
■ Charging precautions
NEVER attempt to charge dry cell batteries. This will cause
internal liquid leakage and damage the receiver.
NEVER connect two or more chargers at the same time.
Charging may not occur under temperatures of 10°C (50°F)
or over temperatures of 40°C (104°F).
■ About Ni-Cd batteries
Ni-Cd battery life
If your Ni-Cd batteries seems to have no capacity even after
being fully charged, completely discharge them by leaving the
power ON overnight. Then, fully charge the Ni-Cd batteries
again. If the Ni-Cd batteries still do not retain a charge (or
very little), new batteries must be purchased.
Recycling information (U.S.A. only)
The product that you purchased contains
rechargeable batteries. The batteries are recyclable. At the end of their useful life, under vari-
ous state and local laws, it may be illegal to
dispose of these batteries into the municipal waste stream.

■ General
Operating the IC-R10 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 chapter.
What is VFO?
The IC-R10 has several operating
modes, each of which has its own distinct functions. VFO (Variable
Frequency Operation) is one of these
modes.
VFO mode is used to change the operating frequency, receive mode, tuning
step, etc. Therefore, for most every day
operations of the receiver, you will be
using VFO mode.
■ Selecting VFO mode
1. Turn power ON
Push [POWER] for 1 sec. to turn
power ON.
•Opening message is displayed for 1
sec.
2. Adjust the volume
Adjust the audio to a suitable level
using [VOL].
Check the squelch position (see next
page) or VSC function setting (p. 38)
if no audio is emitted.
10
3
BASIC OPERATION
3. Adjust the squelch
Rotate [SQL] maximum counterclockwise, then rotate it clockwise
until audio is just muted when receiving no signal for FM, WFM or AM
mode. (see right page)
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 changes the
squelch setting. This is useful for
weak signal reception (p. 64).
3-1. Adjust the RF gain
Rotate [SQL] maximum counterclockwise, to adjust RF gain to optimum level.
What is RF gain?
RF gain controls receive sensitivity
gain—reduce the gain when you
don’t want to receive very weak signals or when excessively strong interfering signals are being received,
etc.
4. Select VFO mode
When MEMORY mode is selected,
push [V/M] to select VFO mode.
When SET or TS set mode is selected, push [CLR] to select VFO
mode.
• The VFO indicator appears.

■ Selecting a receive mode
What are receive modes?
Radio signals can be propagated in a variety of ways (or
modes). Each mode has its own physical properties that determine to some degree its uses.
The IC-R10 receives the 6 most common modes: AM, FM,
WFM, USB, LSB and CW. When you want to tune a station,
you MUST set the receive mode first. The table below shows
common uses for each mode.

BASIC OPERATION
■ Selecting a tuning step
What are tuning steps?
Tuning steps are the frequency change
increments when you rotate the tuning
control or operate a scan. The following
steps are available: 0.1, 0.5, 1, 5, 6.25,
8, 9, 10, 12.5, 15, 20, 25, 30, 50, 100
kHz and user programmable tuning
steps (p. 66).
It is important to set the proper tuning
step for the type of station you want to
listen to. Some tuning steps are determined 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 a station you want
(or scan it), however, tuning (or scanning) will not be 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.
Consult local listings.
1. Call up the tuning step
set mode
Once you have selected VFO mode
and the desired receive mode, while
pushing [FUNC], push [
(MODE)TS].
2. Select the tuning step
q Rotate [DIAL] to select the desired
tuning step.
w Push [CLR] to return to VFO
mode after the selection.

BASIC OPERATION
■ Tuning a frequency (via the dial)
When you want to listen to frequencies
near the displayed frequency, the easiest way to tune them is with the tuning
dial.
All signals have what is called an “occupied bandwidth.” They will be received as long as the receiver is tuned
anywhere within this bandwidth. Even
though the frequency received may not
be 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 signal
strength indicator deflection.
To change frequencies faster than the
tuning step, use the dial select function
(p. 16).
1. Select VFO mode and
a receive mode
q Push [CLR] or [V/M] to select VFO
mode.
w Push [MODE] to select a receive

■ Dial select steps
What are dial select steps?
When tuning with the dial, if you want to change the frequency faster than the selected tuning step can, 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:

BASIC OPERATION
■ Band scope function
What is the band scope function?
The band scope detects signal availability in the range of ±5
channels (up to ±100 kHz) from the displayed frequency, and
displays the result on the multi function dot-matrix display.
This gives you a visual reference of current band conditions.
In this case, channel refers to sweep step or channel space
according to the set tuning step. For example, when the tuning step is set to 5 kHz, the band scope detects 25 kHz above
and below the displayed frequency, then displays the result
on the LCD.
When the tuning step is set above 20 kHz, the band scope
function automatically changes its sweep step to 20 kHz.
However, when the sweep step is changed to 20 kHz, the
tuning step remains the same.
Also, when a user-programmable tuning step is selected, the
band scope function automatically selects the 20 kHz sweep
step.
Preparation
The band scope function is activated only when FM receive
mode is selected in VFO mode.
